Retrying commands seldomly works, most often the firmware is in a
weird state anyway and needs the device to reset. So it's better
to report the broken state back to user-space.
Also rename command_timer_fn() into lbs_cmd_timeout_handler(),
which better reflect it's usage.

mac80211 uses unit units of 32 usec with txop but wl1251_acx_ac_cfg()
expects it to be usecs. This fortunately didn't cause any severe problems,
only that firmware was using incorrect WMM settings.

If b43 or b43legacy are deauthenticated or disconnected, there is a
possibility that a reconnection is tried with the queues stopped in
mac80211. To prevent this, start the queues before setting
STAT_INITIALIZED.
In b43, a similar change has been in place (twice) in the
wireless_core_init() routine. Remove the duplicate and add similar
code to b43legacy.

For debugging hardware scan trigger/complete
functionality, it was useful to have code in
hwsim that pretends to do a hardware scan.
This code could be extended to actually do the
scan, but for now it was sufficient for me to
only pretend. Since hwsim was written to ease
debugging, it only makes sense to add it to it
permanently.

This change corrects an issue that will cause false hangs when using either
82575 or 82580 in legacy interrupt mode. The issue is caused when there is
a slow traffic flow and an "ethtool -r" is executed while using legacy or
MSI interrupts. MSI-X is not affected by this issue due to the fact that
we were already reconfiguring the vectors after reset.
If possible it would be best to push this for net-2.6 since it is resolving
a bug but if that is not possible then net-next-2.6 will be fine.

If receive buffer mapping failed, then it was possible to get
stuck with unmapped receive buffer in DMA ring.
This would be an extremely rare condition because the driver had just
released the map for the last receive so it should be able to get
another map again (in soft-irq).

This patch addresses concerns about efficiency of handling incoming
packets. Handling of interrupts is done in a threaded interrupt handler
which has a smaller latency than workqueues. This change needed a rework
of the locking scheme that was much simplified. Some other (more or less
longstanding) bugs are fixed: utilization of just half of the RX
buffers, useless wait for interrupt on open, more reliable reset
sequence. The MERR interrupt is not used anymore: it overloads the CPU
in error-passive state without any additional information. One shot mode
is disabled because it's not clear if it can be handled efficiently on
this CAN controller.

In order to use macvlan with qemu and other tools that require
a tap file descriptor, the macvtap driver adds a small backend
with a character device with the same interface as the tun
driver, with a minimum set of features.
Macvtap interfaces are created in the same way as macvlan
interfaces using ip link, but the netif is just used as a
handle for configuration and accounting, while the data
goes through the chardev. Each macvtap interface has its
own character device, simplifying permission management
significantly over the generic tun/tap driver.
