b43: Changes to enable BCM4311 rev 02 with wireless core revision 13

The BCM94311MCG rev 02 chip has an 802.11 core with revision 13 and
has not been supported until now. The changes include the following:

(1) Add the 802.11 rev 13 device to the ssb_device_id table to load b43.
(2) Add PHY revision 9 to the supported list.
(3) Change the 2-bit routing code for address extensions to 0b10 rather
    than the 0b01 used for the 32-bit case.
(4) Remove some magic numbers in the DMA setup.

The DMA implementation for this chip supports full 64-bit addressing with
one exception. Whenever the Descriptor Ring Buffer is in high memory, a
fatal DMA error occurs. This problem was not present in 2.6.24-rc2 due
to code to "Bias the placement of kernel pages at lower PFNs". When
commit 44048d70 reverted that code, the DMA error appeared. As a "fix",
use the GFP_DMA flag when allocating the buffer for 64-bit DMA. At present,
this problem is thought to arise from a hardware error.

work to be done on 802.11a support. Note that A PHY initialization involves
G PHYs as well.

pasemi_mac: Improve RX interrupt mitigation

pasemi_mac: Improve RX interrupt mitigation

Currently the receive side interrupts will go off on the reception of
a packet, NAPI will poll the ring and keep polling as long as there's
a decent amount of packets to receive.

This is less than optimal, especially for LRO where it's better if we
have a more substantial amount of packets to process at once, to get
the real LRO benefits.

So, set the count threshold to a higher value and use the timeout feature
that will give us an interrupt even if not enough packets have come in
to set off the count threshold.

FIXME: It'd be real nice to have ethtool support for users to tune this
at runtime.

This is a bit awkward. We don't have a timer-delayed interrupt on TX
complete, but we have a count threshold. So set that reasonably high
(32 packets), and schedule the NAPI poll when it goes off. Also bump a
regular timer that will take care of rotting packets for the last 1..31
ones in case we don't trigger a TX interrupt (and there's no RX activity
that would otherwise trigger the poll).

The longer-term fix is to separate TX from RX NAPI and do two separate
poll loops.
