The tx_headroom required for mwl8k driver is 32 bytes and it
can use the space for 802.11 header received from mac80211.
mwl8k considers the smallest 802.11 frame (CTS2self of 10
bytes) that can be received from mac80211 to compute the
extra_tx_headroom as 22 (32 - 10) bytes.
When the wireless interface is part of bridge, this
extra_tx_headroom requirement results in a memcpy in
mac80211 (in function pskb_expand_head) for all the data
frames needing L2 forwarding/bridging, when NET_SKB_PAD is
defined as 32. This patch reduces the extra_tx_headroom by
8 bytes so that memcpy of data frames in mac80211 is
avoided in this case.
The resize will be required in driver for frames with 802.11
header size of less than 18 bytes.

We mark command as huge by using meta->flags from other (non huge) command,
but flags can be possibly overridden, when non huge command is enqueued,
what can lead to:
WARNING: at lib/dma-debug.c:696 dma_debug_device_change+0x1a3/0x1f0()
DMA-API: device driver has pending DMA allocations while released from device [count=1]
To fix introduce additional CMD_MAPPED to mark command as mapped and
serialize iwl_enqueue_hcmd() with iwl_tx_cmd_complete() using
hcmd_lock. Serialization will also fix possible race conditions,
because q->read_ptr, q->write_ptr are modified/used in parallel.

iwlwifi: do not set tx power when channel is changing
we set device tx power during initialization to priv->tx_power_next,
which itself is initialized to minimum power. That changed
default behaviour of driver. Previously we initialized device to
transmit at maximum available power by default. Patch change again
to previous behaviour and cleanup tx power initialization.
Fortunately this is not critical fix, as mac80211 layer setup
tx power lately to 14dB, hence device does not operate at minimal
transmit power all the time.

It occured during some stress testing, in which the reporter was repeatedly
removing and modprobing the bnx2 module while doing various other random
operations on the bnx2 registered net device. Noting that this error occured on
a serdes based device, we noted that there were a few ethtool operations (most
notably self_test and set_phys_id) that have execution paths that lead into
bnx2_setup_serdes_phy. This function is notable because it executes a mod_timer
call, which starts the bp->timer running. Currently bnx2 is setup to assume
that this timer only nees to be stopped when bnx2_close or bnx2_suspend is
called. Since the above ethtool operations are not gated on the net device
having been opened however, that assumption is incorrect, and can lead to the
timer still running after the module has been removed, leading to the oops above
(as well as other simmilar oopses).
Fix the problem by ensuring that the timer is stopped when pci_device_unregister
is called.
