Improve the firmware selection by adding 2 cases where we should use the
optimized firmware:
* when the actual PCIe link width is lower than 8x.
* when the board is plugged to one of the new Intel PCIe chipsets that
are known to provide aligned PCIe completions.
The patch actually raises two concerns:
* We might want to add a generic PCI function to get the PCIe link width since
some other drivers (at least ipath) do the same. But we probably do not want
to add a new function for every PCIe capability. I will probably look at it
and discuss it on linux-pci in the future.
* As requested during the submission, the PCI ids of chipsets that are known to
provided aligned completion are defined in the myri10ge code. If we keep adding
new ones, it might become better to move them to pciids.h.
But, this sort of quirk to detect these chipsets are very specific to our NIC,
I don't think it is worth moving it to the PCI core until somebody else really
needs it.

The airo driver is currently caching a pid for later use, but with the
implementation of containers, pids themselves do not uniquely identify a
task. The driver is also using kernel_thread() which is deprecated in
drivers.
This patch essentially replaces the kernel_thread() with kthread_create().
It also stores the task_struct of the airo_thread rather than its pid.
Since this introduces a second task_struct in struct airo_info, the patch
renames airo_info.task to airo_info.list_bss_task.
As an extension of these changes, the patch further:
- replaces kill_proc() with kthread_stop()
- replaces signal_pending() with kthread_should_stop()
- removes thread completion synchronisation which is handled by
kthread_stop().

The UCC(Unified Communications Controller) module of QE can work as gigabit
Ethernet device. This patch provides driver for the device.

Fix a subtle race condition between bnx2_start_xmit() and bnx2_tx_int()
similar to the one in tg3 discovered by Herbert Xu:
CPU0 CPU1
bnx2_start_xmit()
if (tx_ring_full) {
tx_lock
bnx2_tx()
if (!netif_queue_stopped)
netif_stop_queue()
if (!tx_ring_full)
update_tx_ring
netif_wake_queue()
tx_unlock
}
Even though tx_ring is updated before the if statement in bnx2_tx_int() in
program order, it can be re-ordered by the CPU as shown above. This
scenario can cause the tx queue to be stopped forever if bnx2_tx_int() has
just freed up the entire tx_ring. The possibility of this happening
should be very rare though.
The following changes are made, very much identical to the tg3 fix:
1. Add memory barrier to fix the above race condition.
2. Eliminate the private tx_lock altogether and rely solely on
netif_tx_lock. This eliminates one spinlock in bnx2_start_xmit()
when the ring is full.
3. Because of 2, use netif_tx_lock in bnx2_tx_int() before calling
netif_wake_queue().
4. Add memory barrier to bnx2_tx_avail().
5. Add bp->tx_wake_thresh which is set to half the tx ring size.
6. Check for the full wake queue condition before getting
netif_tx_lock in tg3_tx(). This reduces the number of unnecessary
spinlocks when the tx ring is full in a steady-state condition.

Also made some modifications to the clear functions:
After a discussion on the mailing list, I implemented this code to
have on the one hand sufficient test in debug mode, but on the
other hand reduce the overhead for structure clearing to a
minimum.
A new macro ZD_MEMCLEAR is introduced, which produces code if
DEBUG is set. Locks are not set anymore for structure clearing,
but in debug mode, there is a verification, that the locks have
not been set.
Finally, removed a misleading comment regarding locking in the disconnect
