This patch introduces a new handler get_hw_cmd_size in hcmd_utils,
which should adjust the size of the command sent to the microcode
according to the current nic.
It also changes the RXON flow to make usage of this new handler.
The patch also adds iwl_rxon_cmd structure which is supperset for
5000 HW and 4965.

This patch follows the 11n spec in separation between Tx and Rx MCS
capabilities. Up until now, when configuring the HT possible set of Tx
MCS only Rx MCS were considered, assuming they are the same as the Tx MCS.
This patch fixed this by looking at low level driver Tx capabilities.

[PATCH, take 2] libertas: reduce command retry time
In the normal case, an unsuccessful command would be retried for 10*5 seconds,
or 10*10 seconds in the worst case. This patch reduces this to 3*3 seconds,
or 3*10 seconds in the worst case.
I also reduced the time it takes to start a new command downloaded.

The mesh_path_node_copy() can be called like this:
mesh_path_add
`- write_lock(&pathtbl_resize_lock); /* ! */
`- mesh_table_grow
`- ->copy_node
`- mesh_path_node_copy
thus, the GFP_KERNEL is not suitable here.
The acceptable fix, I suppose, is make this allocation GPF_ATOMIC -
the mpath_node being allocated is 4 pointers, i.e. this allocation
is small enough to survive even under a moderate memory pressure.

The mesh_path_node_copy() performs kmalloc() and thus - may fail
(well, it does not now, but I'm fixing this right now). Its caller -
the mesh_table_grow() - isn't prepared for such a trick yet.
This preparation is just flush the new hash and make copy_node()
return an int value.

(This set applies OK without the previous one of 4 patches,
but with some fuzz in the 7th one)
The mesh_path_node_free() does so under hashwlock.
But, this one is called
1. from mesh_path_add() after an old hash is hidden and
synchronize_rcu() is calld
2. mesh_pathtbl_unregister(), when the module is being
unloaded and no devices exist to mess with this hash.
So, it seems to me, that simply removing the call is OK.

This patch is based on a patch from Shailendra Govardhan and Brian Cavagnolo.
It extends the MESH_CONFIG command to configure non-volatile parameters on
libertas devices that support them (e.g. OLPC Active Antenna).
This patch only implements the driver/firmware interface.
See http://dev.laptop.org/ticket/6823 for minimal testing results and known

We weren't properly handling multicast on the mesh interface. Fix that,
which involves setting up the hardware to use the union of dev->mc_list
for both eth%d and msh%d devices.
This means we can't do it directly from ->set_multicast_list() because
we'd need to lock the other device to read its list, and we can't do
that because it might deadlock. So punt the actual work to keventd.
Also, invoke the same when taking an interface down; for some reason the
core calls ->set_multicast_list while IFF_UP is still set in dev->flags
when we're taking it down, so its addresses don't get removed then.
We also convert MAC_MULTICAST_ADR to a direct command while we're at it,
removing one more entry from the big switch statement in the deprecated
lbs_prepare_and_send_command() function.

Using the deprecated lbs_prepare_and_send_command() function for a
command which it doesn't understand is an error; complain loudly about
it even when we're not debugging.
The mesh stats bug, where we converted MESH_ACCESS to a direct command
but accidentally missed one user which was still trying to do it through
lbs_prepare_and_send_command(), would have been caught a lot quicker if
we'd done this sooner. Such bugs aren't entirely unlikely in future too,
as we convert more code to stop using this function.

the rxdesc structure is properly memsetted before passed to
the driver. This means we don't have to reinitialize the flags
and dev_flags fields in the drivers again.
This will prevent problems when the rxdone handler is adding
flags in a earlier status and will make the code look nicer
when we are adding more read attributes in the rxdone handler
in the driver.

Split rt2x00lib_write_tx_desc() up into a TX descriptor initializor
and TX descriptor writer.
This split is required to properly allow mac80211 to move its
tx_control structure into the skb->cb array.
The rt2x00queue_create_tx_descriptor() function will read all tx control
information and convert it into a rt2x00 TX descriptor information structure.
After that function is complete, we have all information we needed from the
tx control structure and are free to start writing into the skb->cb array
for our own purposes.
rt2x00queue_write_tx_descriptor() will be in charge of really sending
the TX descriptor to the hardware and kicking the TX queue.

Due to usage of memmove() in rt2x00usb the descriptor can become
corrupted because it is being overwritten by the data part.
Overall having the descriptor in front of the frame is a bad idea,
we can however use the skb->cb array for this task, since that
contains more then enough room to hold the entire descriptor and
preserve the information long enough.
After this we can also cleanup the alignment code a bit to make it
work a bit more flexible to allow for all kinds of odd header lengths.

feature.
With the integration of the mac80211 multiqueue patches it has become possible that the
mac80211 layer modifies the number of TX queues that is stored inside the ieee80211_hw
structure, especially when multi-queue is not selected.
The rt2x00 drivers are not well suited to handle that situation, as they allocate the
queue structures before mac80211 has modified the number of queues it is going to use,
and also expect the number of allocated queues to match the hardware implementation.
Hence, ensure that rt2x00 maintains by itself the number of queues that the hardware
supports, and, at the same time, making is not dependent on the preservation of contents
inside a mac80211 structure.

The tx_status enumeration was broken since the introduction
of rt61pci. That driver uses different values to report the
status of the tx action.
This would lead to frames that were reported as success but
actually failed to be send out, or frames that were neither
successfull or failure which were reported as failure.
Fix this by change the TX status reporting and more explicitely
check for failure or success. Note that a third possibility is
added "unknown". Not all hardware (USB) can report the actual
TX status, for rt61pci some frames will receive this status
because the TXdone handler is never called for those frames.
This unknown will now be handled as neither success or failure,
so we no longer increment the failure counter while this conclusion
could not be determined from the real status of the frame.

Remove frame_type from skb_frame_desc and pass it
as argument to rt2x00debug_dump_frame().
Change data_len and desc_len to unsigned short
to save another 4 bytes in skb_frame_desc. Note that
this was the only location where the data_len and
desc_len was not yet treated as unsigned short.
This trim is required to help mac80211 with adding
the TX control and TX status informtation into the
skb->cb structure. When that happens, drivers will
have approximately 40 bytes left to use freely.

This patch modifies TIPC's network topology service so that it
only requires a single reference table entry per subscriber
connection, rather than two. This is achieved by letting the
reference to the server port communicating with the subscriber
act as the reference to the subscriber object itself. (Since
the subscriber cannot exist without its port, and vice versa,
this dual role for the reference is perfectly natural.) This
consolidation reduces the size of the reference table by 50%
in the default configuration.

This patch fixes TIPC's topology server so that it does byte swapping
correctly when endianness conversion is required. (Note: This bug only
impacted an application if it issues a subscription request to a
topology server on another node, rather than the server on it's own
node; since the topology server is normally not accessible by off-node
applications, most TIPC applications were not impacted by the bug.)
