In a situation either with expanders or with multiple enclosure
devices, hot add doesn't always work. This is because we try to find
a single enclosure device attached to the host. Fix this by looping
over all enclosure devices attached to the host and also by making the
find loop recognise that the enclosure devices may be expander remote
(i.e. not parented by the host).

When bnx2i_adapter_ready() fails, connection handle(cid) = 0 is wrongly freed
because 'cid' is not yet allocated for the endpoint. Fix is to initialize
bnx2i_ep->ep_iscsi_cid to '-1' in bnx2i_alloc_ep() and not in
bnx2i_ep_connect() to avoid releasing invalid 'cid'. There is already a check
in bnx2i_free_iscsi_cid() not to free invalid iscsi connection handle (-1)

Without the fix bnx2i would fail tt->xmit_task() when link is down and
libiscsi would have already incremented session->cmdsn before calling bnx2i's
xmit_task() entry point and will just return the command to SCSI-ML when
xmit_task() fails. libiscsi does not retract the session->cmdsn as the command
was never sent on wire. It is generally good idea for LLD, bnx2i to accept
the scsi cmnd/nopout and let upper layer timeout and go though normal session
recovery process. When link is down, unsolicited nopout will not be accepted
by bnx2i and connection will never enter recovery state. This fix is required
for MPIO to work corectly

The phys_dev was used only to locate common offload EM instance for all
FCoE instances on a eth devices in function fcoe_em_config, so just updated
fcoe_em_config to look for actual real eth device in locating common offload
EM instance and then no need to store phys_dev in fcoe_softc, so removes
phys_dev from fcoe_softc also.
Renames fcoe_softc real_dev to netdev and updates all its uses to use netdev.
So effectively no functional change, use of single netdev instead phys_dev
and real_dev saves one pointer memory in fcoe_softc, also real_dev used here
was confusing with vlan driver terminology since real_dev in vlan driver is
referred to physical eth device.

FC_FRAME_SG_LEN is 4 which is too small when offload is enabled. Actually, the
WARN_ON() in fc_fcp_send_data() should be:
WARN_ON(skb_shinfo(fp_skb(fp))->nr_frags > MAX_SKB_FRAGS);
But since we will not get anything more than 64K anyway, so there is no need
to do this anyway here. Therefore, I am getting rid of FC_FRAME_SG_LEN here
and the WARN_ON here.

range per EM
Updates fcoe_em_config to allocate a single instance of sharable offload
EM for supported lp->lro_xid per eth device, and then share this EM
for subsequently more lports creation on same eth device (e.g when using
VLAN).
Adds tiny fcoe_oem_match function for offload EM to return true for read
types IO to have read IO exchanges allocated from offload shared EM.
Removes fc_em_alloc_xid function completely which was needed to manage
two xid ranges within a EM, this is not needed any more with allocation
of separate sharable offload EM per eth device. Instead this patch adds
simple xid allocation logic to manage single xid range.
Adds fc_exch_em_alloc with mp->next_xid as cursor to allocate new xid
from single xid range of EM, uses mp->next_xid instead removed mp->last_xid
which slightly increase probability of finding empty xid on exch allocation.
Removes restriction of not allowing use of xid zero along with changing
two xid range change to single xid range.
Makes fc_fcp_ddp_setup calling conditional to only xid allocated from
shared offload EM.

Modifies current code to use EM anchor list in EM allocation, EM free,
EM reset, exch allocation and exch lookup code paths.
1. Modifies fc_exch_mgr_alloc to accept EM match function and then
have allocated EM added to the lport using fc_exch_mgr_add API
while also updating EM kref for newly added EM.
2. Updates fc_exch_mgr_free API to accept only lport pointer instead
EM and then have this API free all EMs of the lport from EM anchor
list.
3. Removes single lport pointer link from the EM, which was used in
associating lport pointer in newly allocated exchange. Instead have
lport pointer passed along new exchange allocation call path and
then store passed lport pointer in newly allocated exchange, this
will allow a single EM instance to be used across more than one
lport and used in EM reset to reset only lport specific exchanges.
4. Modifies fc_exch_mgr_reset to reset all EMs from the EM anchor list
of the lport, adds additional exch lport pointer (ep->lp) check for
shared EM case to reset exchange specific to a lport requested reset.
5. Updates exch allocation API fc_exch_alloc to use EM anchor list and
its anchor match func pointer. The fc_exch_alloc will walk the list
of EMs until it finds a match, a match will be either null match
func pointer or call to match function returning true value.
6. Updates fc_exch_recv to accept incoming frame on local port using
only lport pointer and frame pointer without specifying EM instance
of incoming frame. Instead modified fc_exch_recv to locate EM for the
incoming frame by matching xid of incoming frame against a EM xid range.
This change was required to use EM list in libfc Rx path and after this
change the lport fc_exch_mgr pointer emp is not needed anymore, so
removed emp pointer.
7. Updates fnic for removed lport emp pointer and above modified libfc APIs
fc_exch_recv, fc_exch_mgr_alloc and fc_exch_mgr_free.
8. Removes exch_get and exch_put from libfc_function_template as these
are no longer needed with EM anchor list and its match function use.
Also removes its default function fc_exch_get.
A defect this patch introduced regarding the libfc initialization order in
the fnic driver was fixed by Joe Eykholt <jeykholt@cisco.com>.

Currently there is a 1:1 relationship between the lport
and exchange manager. This macro takes an EM as an argument
and determines the lport from it. However, later patches
will use an EM list per lport, so we will no longer have
this 1:1 relationship- this macro must change.
The FC_EM_DBG macro is rarely used. There are four callers,
two can use FC_LPORT_DBG instead and two can be removed
since they're not necessary. This patch makes those changes
and removes the macro.

related APIs
Adds EM list using a anchor struct fc_exch_mgr_anchor, anchor is used
to allow same EM instance sharing across more than one lport on a eth
device, this implementation is per discussed design posted at
http://www.open-fcoe.org/pipermail/devel/2009-June/002566.html.
The shared EM is required for multiple lports on eth device when
using multiple VLANs or NPIV.
Adds fc_exch_mgr_add API to add a EM to the lport and fc_exch_mgr_del
API to delete previously added EM.
Also adds function fc_exch_mgr_destroy() to destroy allocated EM.
The kref is added to the EM to keep track of EM usage count, the EM is
destroyed when no longer in use upon kref reaching to zero.
The caller can specify match function to fc_exch_mgr_add, this
will be used in determining exchange allocation from its EM or not.
Moved calling of fcoe_em_config below fcoe_libfc_config calling,
so that list head lp->ema_list is initialized before configuring
EM.

fc_rport_logoff drops the rport lock in order to cancel work
that may be pending. This is undesirable as the state can
completely change, and the caller may not expect that the
lock could've been dropped.
If there is work pending, it will acquire the rdata mutex and
so we're protected and can change the event from READY to DELETE.
Queue the work only if there is no event already pending.
There were a couple other cases where the state was set to
DELETE and work queued, even though the state may have already
been DELETE. Fix these using a common function fc_rport_enter_delete().

State RPORT_ST_NONE was intented to be an invalid state (0), never used.
This was a misguided attempt to be sure it was always initialized.
Having an extra state meaning nothing requires switch statements to
have a case covering that state.

During an fcoe module unload, we saw a problem where fc_rport_work()
finds the lport has been freed. The rdata points to an area
containing 0x6b6b6b6b... the pool poison value from kmem_free().
In fcoe_if_destroy() we call fc_fabric_logoff() then fc_lport_destroy().
fc_fabric_logoff() flushes the remote port work, but we're still receiving
requests, and an RSCN or PLOGI arrives which creates more rports.
Note that although the LLD also checks link_up, it doesn't do it
under the lport mutex, so it can deliver frames to
fc_lport_recv_req() even after link_up is cleared.
So, re-check link_up there.
We need to flush the rports by calling disc_stop_final()
after we clear link_up.

When removing the fcoe module, several lports were being shut down
through fc_lport_fabric_logoff().
Occasionally, one would enter reset state before fc_lport_destroy()
was called, and since link_up was still true, it would log back in.
If we just clear link_up earlier, then we wouldn't be accepting LOGO
requests from other initiators while we are shutting down.
Fix by changing the LOGO response handler to enter DISABLED instead
of RESET. Add an fc_lport_enter_disabled() function which does
what fc_lport_enter_reset() did, except it doesn't proceed to FLOGI state.
Move the code that was common between fc_lport_enter_reset() and
fc_lport_enter_disabled() into a new fc_lport_reset_locked() function.

libfc debug messages currently show 'lport: <fc-id>:'
wher <fc-id> is the hex assigned port-id. When the lport
is logged off, that will be zero, so its hard to distinguish
which instance is involved. The FC-ID can change
if the port is re-patched or changes VSANs.
Two lports may even have the same FC-ID if connected to isolated SANs.
Change the debug messages to print the SCSI host number "hostN:",
which will not change for the life of the lport.
Still show the FC_ID on lport messages.
Also, add a macro to FC_RPORT_ID_DBG for rport debugging where there's
no rdata structure involved. It takes the lport and port_id as parameters.
Use this in fc_rport_recv_plogi_req() and fc_rport_recv_logo_req().

when the last connection is torn down. Next call to ep_connect() will fail
because the device is not registered. This issue is not seen if shost == NULL
is passed to ep_connect() call because in that case bnx2i will registers all
known devices with cnic before doing a route look-up. When shost != NULL,
bnx2i knows the device on which to offload the connection and has to register
this device before attempting to offload the connection

When a request fails we print the sense data but not the actual command
that failed. Add a printout of the operation + CDB for failed commands.

Problem reported: http://marc.info/?l=dm-devel&m=124585978305866&w=2
scsi_dh does not do a refernce count for attach/detach, and this affects
the way it is supposed to work with multipath when a device is not
in the dev_list of the hardware handler.
This patch adds a reference count that counts each attach.

It has been 3 years since this file was sync-ed with
www.t10.org . Information taken from the last bunch
of drafts released in May 2009. More asc/ascq codes
are coming for thin provisioning; when approved and
allocated another patch could add them prior to this
patch going live.
Changelog:
- add some new command names and rename two commands
- sync asc/ascq table with www.t10.org/lists/asc-num.txt
- correct bug in scsi_extd_sense_format() [second
for loop]
