The new FW improves the packets per second rate. It required a lot of change in
the FW which implies many changes in the driver to support it. It is now also
possible for the driver to use a separate MSI-X vector for Rx and Tx - this also
add some to the complicity of this change.
All things said - after this patch, practically all performance matrixes show
improvement.
Though Vladislav Zolotarov is not signed on this patch, he did most of the job
and deserves credit for that.

As it is, parts of the ioctl runs under the RTNL and parts of
it do not. The unlocked section is still protected by the BKL,
but there can be subtle races. For example, Eric Biederman and
Paul Moore observed that if two threads tried to create two tun
devices on the same file descriptor, then unexpected results
may occur.
As there isn't anything in the ioctl that is expected to sleep
indefinitely, we can prevent this from occurring by extending
the RTNL lock coverage.
This also allows to get rid of the BKL.
Finally, I changed tun_get_iff to take a tun device in order to
avoid calling tun_put which would dead-lock as it also tries to
take the RTNL lock.

Commit f0b3fbeae1 ("FEC Buffer rework")
breaks transmission of packets where the skb data buffer is not memory
aligned according to FEC_ALIGNMENT. It incorrectly passes to
dma_sync_single() the buffer address directly from the skb, instead of
the address calculated for use (which may be the skb address or one of
the bounce buffers).
It seems there is no use converting the cpu address of the buffer to
a physical either, since dma_map_single() expects the cpu address and
will return the dma address to use in the descriptor. So remove the use
of __pa() on the buffer address as well.
This patch is against 2.6.30-rc5. This breakage is a regression over
2.6.30, which does not have this problem.

This patch fixes a case in the transmit completion code which was resulting
in pktgen hanging at the end of a run. The cause is due to the fact that
the ->cb[] area of an skb cannot be used in a network driver's transmit
path, as that area belongs to the network protocol. Pktgen hangs, as it
sends out the same packet multiple times, and vxge's use of this area of
the skb for a temporary list can only add the packet to the temporary list
once (while it may be on the queue many times). The fix is to remove this
abuse of skb->cb[]. Instead, skb pointers are placed into a temporary
stack array, and then free outside of the tx lock. This retains the smp
optimization of doing dev_kfree_skb() outside of the tx lock.

The skb priority to vlan-qos egress mapping that can be configured using
set_egress_map with vconfig is overriden by the DCB code in the driver.
This patch allows this existing mechanism to work and will increase the
configuration flexibility of DCB mode on Linux.
A hierarchy of configuration is:
1. Modifies the ixgbe_select_queue() routine for DCB mode to return the
priority value from the VLAN tag. It will normally be zero, unless the egress
priority map has modified it. This will get packets into the correct queue and
result in the queue_mapping field being set correctly.
2. Any tc filter which modifies queue_mapping will be honored, as the filters
are handled after the vlan egress map is handled.

This patch adds support for fixed PHY connected in MII mode
to cpmac. We allow external and dumb_switch module parameters
to override the PHY detection process since they are always connected
with MDIO bus identifier 0. This lets fixed PHYs to be detected
correctly and be connected to the their corresponding MDIO
bus identifier.

This patch fixes the wrong MDIO bus identifier which was
set to 0 unconditionaly, suitable for external switches while
it is actually 1 for PHYs different than external switches
which are autodetected.

If hw initialization fails (ath9k_hw_init()) on ath_init_softc()
we bail out and call ath9k_hw_detach(). The call ath9k_hw_detach()
is conditional though as ath9k_hw_init() could itself have called
ath9k_hw_detach(). Just describing this is itself a brain twister.
Avoid this nonsense by removing ath9k_hw_detach() from ath9k_hw_init().
Upon hw initialization failure we expect the callers to take care of
the cleanup.

During initialization ath9k tends to use "attach" to when we
initialize hardware due to the fact we used to attach a "HAL".
The notion of a HAL is long gone, so lets just be clear on what
we are doing.

This makes reading the hardware initialization process
easier to understand. The new helpers added are:

ath9k_hw_init_mode_gain_regs()
ath9k_hw_init_11a_eeprom_fix()
