This patch makes it so that igb now uses the DMA API functions instead of
the PCI API functions. To do this the pci_dev pointer that was in the
rings has been replaced with a device pointer, and as a result all
references to [tr]x_ring->pdev have been replaced with [tr]x_ring->dev.
This patch is based of of work originally done by Nicholas Nunley.

The bonding driver calls ndo_vlan_rx_register() while holding bond->lock.
The bnx2 driver calls bnx2_netif_stop() to stop the rx handling while
changing the vlgrp. The call also stops the cnic driver which sleeps
while the bond->lock is held and cause the warning.
This code path only needs to stop the NAPI rx handling while we are
changing the vlgrp. Since no reset is going to occur, there is no need
to stop cnic in this case. By adding a parameter to bnx2_netif_stop()
to skip stopping cnic, we can avoid the warning.

It has been reported that under certain heavy traffic conditions in MSI-X
mode, the driver can lose an MSI-X vector causing all packets in the
associated rx/tx ring pair to be dropped. The problem is caused by
the chip dropping the write to unmask the MSI-X vector by the kernel
(when migrating the IRQ for example).
This can be prevented by increasing the GRC timeout value for these
register read and write operations.

Quote from comment #17:
"The problem is the innocent looking moving of the tx processing to
after the rx processing in the tasklet. Quoting from the changelog:
This patch does it the same way, except that it also prioritize
rx data processing, simply because tx routines *can* wait.
This is causing an issue with us referencing already freed memory,
because some skb's we transmit, we immediately receive back, such
as those for reading the eeprom (*) and getting stats.
What can happen because of the moving of the tx processing to after
the rx processing is that when the tasklet first runs after doing a
special skb tx (such as eeprom) we've already received the answer
to it.
Then the rx processing ends up calling p54_find_and_unlink_skb to
find the matching tx skb for the just received special rx skb and
frees the tx skb.
Then after the processing of the rx skb answer, and thus freeing
the tx skb, we go process the completed tx ring entires, and then
dereference the free-ed skb, to see if it should free free-ed by
p54p_check_tx_ring()."

When I set up multiple VAPs with ath9k, I encountered an issue that
the traffic may be lost after a while.
The detailed phenomenon is
1. After a while the clients connected to one of these VAPs will get
into a state that no broadcast/multicast packets can be transfered
successfully while the unicast packets can be transfered normally.
2. Minutes latter the unitcast packets transfer will fail as well,
because the ARP entry is expired and it can't be freshed due to the
broadcast trouble.
It's caused by the group key overwritten and someone discussed this
issue in ath9k-devel maillist before, but haven't work out a fix yet.
I referred the method in madwifi, and made a patch for ath9k.
The method is to set the high bit of the sender(AP)'s address, and
associated that mac and the group key. It requires the hardware
supports multicast frame key search. It seems true for AR9160.
Not sure whether it's the correct way to fix this issue. But it seems
to work in my test. The patch is attached, feel free to revise it.

This patch introduces the parity errors handling code for 57710 and 57711 chips.
HW is configured to stop all DMA transactions to the host and sending packets to the network
once parity error is detected, which is meant to prevent silent data corruption.
At the same time HW generates the attention interrupt to every function of the device where parity
has been detected so that driver can start the recovery flow.
The recovery is actually resetting the chip and restarting the driver on all active functions
of the chip where the parity error has been reported.

This patch adds support for writing multiple registers
in a single USB command.
Specific calls from the HW code that performs multiple
register writes would be modified to make use of this
in subsequent patches.

According to tests, both TSF lower and upper registers kept counting, so
the higher part could have been updated after the lower part has been
read, as shown in the following log where the upper part is read first
and the lower part next.
tsf = {00000003-fffffffd}
tsf = {00000003-00000001}
tsf = {00000004-0000000b}
This patch corrects this by checking that the upper part has not been
changed while the lower part was read. It has been tested in an IBSS
network where artifical IBSS merges have been done in order to trigger
hundreds of rollover for the TSF lower part.
It follows the logic mentionned by Derek, with only 2 register reads
needed at each additional steps instead of 3 (the minimum number of
register reads is still 3).

LDPC is enabled by the rate control if the its determined
that the target peer supports LDPC. We would have already
intersected the HT capabilities so if our peer supports
LDPC so do we.

The AR9002 hardware code enables aggregation for WEP but
mac80211 doesn't enable aggregation with WEP, and the AR9003
code family does not need this so skip it for now for AR9003
but leave the code and annotate we should eventually consider
how to remove this in consideration for the HAL unification
goals.
