The static function max2820_rf_set_channel is called with conf == NULL
within its compilation unit. Originally this defaulted to b/g channel
1, but "cfg80211 API for channels/bitrates, mac80211 and driver
conversion" (commit 8318d78a44) mistakenly
dropped this check. This patch minimally restores the expected
behavior.

This adds support for firmware markers.
With firmware markers it's easily possible to check whether the
firmware runs some codepath or not. The driver will throw a message
when the firmware executes a MARKER(x).

This patch converts mac80211 and all drivers to have transmit
information and status in skb->cb rather than allocating extra
memory for it and copying all the data around. To make it fit,
a union is used where only data that is necessary for all steps
is kept outside of the union.

This patch modifies struct ieee80211_tx_control to give band
info and the rate index (instead of rate pointers) to drivers.
This mostly serves to reduce the TX control structure size to
make it fit into skb->cb so that the fragmentation code can
put it there and we can think about passing it to drivers that
way in the future.

4) drops a WEP packet which has been garbaged by firmware. This can

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.
