Previously the driver tweaked txqueuelen to avoid false Tx hang reports
seen at half duplex. This had the effect of overriding user set values
on link change/reset. Testing shows that adjusting only the timeout
factor is sufficient to prevent Tx hang reports at half duplex.
This patch removes all instances of tx_queue_len in the driver.

When cache is unresolved, c->mf[6]c_parent is set to 65535 and
minvif, maxvif are not initialized, hence we must avoid to
parse IIF and OIF.
A second problem can happen when the user dumps a cache entry
where a VIF, that was referenced at creation time, has been
removed.

When running the offline diagnostic tests check to see if any VFs are
online. If so then only run the link test. This is necessary because
the VFs running in guest VMs aren't aware of when the PF is taken
offline for a diagnostic test. Also put a message to the system log
telling the system administrator to take the VFs offline manually if
(s)he wants to run a full diagnostic. Return 1 on each of the tests
not run to alert the user of the condition.

Add new flag MSG_WAITFORONE for the recvmmsg() syscall.
When this flag is specified for a blocking socket, recvmmsg()
will only block until at least 1 packet is available. The
default behavior is to block until all vlen packets are
available. This flag has no effect on non-blocking sockets
or when used in combination with MSG_DONTWAIT.

When a dump is interrupted at the last device in a hash chain and
then continued, "idx" won't get incremented past s_idx, so s_ip_idx
is not reset when moving on to the next device. This means of all
following devices only the last n - s_ip_idx addresses are dumped.

Fix undo of reserve() before RX recycle
gfar_new_skb reserve()s space in the SKB to align it. If an error occurs,
and the skb needs to be returned to the RX recycle queue, the current code
attempts to reset head, but did not reset tail. This patch remembers the
alignment amount, and reverses the reserve() when needed.

During FCF solicitation, the switch is supposed to pad the
solicited advertisement out to the endpoints specified
maximum FCoE frame size. That means that we need to receive
FIP frames that are larger than the standard MTU. To make

If the user buffer count was 256 the shift would place a 1
in the offset region leading to errors. It also overwrites
the uers buffer list. This patch makes sure that at most
256 user buffers are allowed for DDP and the buffer count
is masked properly such that it doesn't overwrite the offset

In the last patch I missed an unecessary min_t comparison.
This patch removes it, the path allocates at most
72 tx queues for 82599 and 24 for 82598 there is no need
for this check.
Additionally this sets MAX_[TX|RX]_QUEUES to 72. Which is
used as the size for the tx/rx_ring arrays. There is no
reason to have more tx_rings/rx_rings then num_tx_queues.

VFs running in guest VMs do not respond in as timely a manner to
PF indication it is going down as they do when running in the host
domain. If the adapter is in SR-IOV mode insert a two second delay
to guarantee that all VFs have had time to respond to the PF reset.
In any case resetting the PF while VFs are active should be
discouraged but if it must be done then there will be a two
second delay to help synchronize resets among the PF and all the
VFs.

The order of the IPv6 raw table is currently reversed, that makes impossible
to use the NOTRACK target in IPv6: for example if someone enters
ip6tables -t raw -A PREROUTING -p tcp --dport 80 -j NOTRACK
and if we receive fragmented packets then the first fragment will be
untracked and thus skip nf_ct_frag6_gather (and conntrack), while all
subsequent fragments enter nf_ct_frag6_gather and reassembly will never
successfully be finished.

The dma map fields in the skb_shared_info structure no longer has any users
and can be dropped since it is making the skb_shared_info unecessarily larger.
Running slabtop show that we were using 4K slabs for the skb->head on x86_64 w/
an allocation size of 1522. It turns out that the dma_head and dma_maps array
made skb_shared large enough that we had crossed over the 2k boundary with
standard frames and as such we were using 4k blocks of memory for all skbs.

This is required to correctly select vlan tx queue for a driver
supporting multi tx queue with ndo_select_queue implemented since
currently selected vlan tx queue is unaligned to selected queue by
real net_devce ndo_select_queue.
Unaligned vlan tx queue selection causes thrash with higher vlan
tx lock contention for least fcoe traffic and wrong socket tx
queue_mapping for ixgbe having ndo_select_queue implemented.
-v2
As per Eric Dumazet<eric.dumazet@gmail.com> comments, mirrored
vlan net_device_ops to have them with and without vlan_dev_select_queue
and then select according to real dev ndo_select_queue present or not
for a vlan net_device. This is to completely skip vlan_dev_select_queue
calling for real net_device not supporting ndo_select_queue.

The bnx2 driver calls netif_napi_add() for all the NAPI structs during
->probe() time but not all of them will be used if we're not in MSI-X
mode. This creates a problem for netpoll since it will poll all the
NAPI structs in the dev_list whether or not they are scheduled, resulting
in a crash when we access structure fields not initialized for that vector.
We fix it by moving the netif_napi_add() call to ->open() after the number
of IRQ vectors has been determined.

Allows the net_cls cgroup subsystem to be compiled as a module
This patch modifies net/sched/cls_cgroup.c to allow the net_cls subsystem
to be optionally compiled as a module instead of builtin. The
cgroup_subsys struct is moved around a bit to allow the subsys_id to be
either declared as a compile-time constant by the cgroup_subsys.h include
in cgroup.h, or, if it's a module, initialized within the struct by
cgroup_load_subsys.
