      [TG3]: Refine DMA boundary setting. · 59e6b434
      由 David S. Miller 提交于 
      Extract DMA boundary bit selection into a seperate
function, tg3_calc_dma_bndry().  Call this from
tg3_test_dma().

Make DMA test more reliable by using no DMA boundry
setting during the test.  If the test passes, then
use the setting we selected before the test.

      [TG3]: Set minimal hw interrupt mitigation. · 15f9850d
      由 David S. Miller 提交于 
      Even though we do software interrupt mitigation
via NAPI, it still helps to have some minimal
hw assisted mitigation.

This helps, particularly, on systems where register
I/O overhead is much greater than the CPU horsepower.

For example, it helps on NUMA systems.  In such cases
the PIO overhead to disable interrupts for NAPI accounts
for the majority of the packet processing cost.  The
CPU is fast enough such that only a single packet is
processed by each NAPI poll call.

Thanks to Michael Chan for reviewing this patch.

      [TG3]: Add tagged status support. · fac9b83e
      由 David S. Miller 提交于 
      When supported, use the TAGGED interrupt processing support
the chip provides.  In this mode, instead of a "on/off" binary
semaphore, an incrementing tag scheme is used to ACK interrupts.

All MSI supporting chips support TAGGED mode, so the tg3_msi()
interrupt handler uses it unconditionally.  This invariant is
verified when MSI support is tested.

Since we can invoke tg3_poll() multiple times per interrupt under
high packet load, we fetch a new copy of the tag value in the
status block right before we actually do the work.

Also, because the tagged status tells the chip exactly which
work we have processed, we can make two optimizations:

1) tg3_restart_ints() need not check tg3_has_work()
2) the tg3_timer() need not poke the chip 10 times per
   second to keep from losing interrupt events

Based upon valuable feedback from Michael Chan <mchan@broadcom.com>

      [PATCH] wireless: 3CRWE154G72 Kconfig help fix · c8920ba0
      由 Daniel Andersen 提交于 
      Version 2 of the 3com OfficeConnect 11g Cardbus Card aka 3CRWE154G72 is not
supported by the prism54 project.  To stop confusion, the kernel
documentation should state so as 3com made a good job hiding the version.

      Fix IBM EMAC driver ioctl bug.

I found IBM EMAC driver bug.
So mii-tool command print wrong status.

  # mii-tool
  eth0: 10 Mbit, half duplex, no link
  eth1: 10 Mbit, half duplex, no link

I can get correct status on fixed kernel.

  # mii-tool
  eth0: negotiated 100baseTx-FD, link okZZ
  eth1: negotiated 100baseTx-FD, link ok

      [PATCH] wireless/airo: WEXT and quality corrections · 41480af2
      由 Dan Williams 提交于 
      This patch brings the airo driver into line with the current
WEXT specification of signal quality.  It also fixes the values
used to determine signal quality and level for MPI & PCMCIA 350
cards.  It turns out that BSSListRid.rssi was actually in dBm
for 350 series cards, and that we can use the normalized
signal strength reported by the card as our "quality" value, on
a scale of 0 - 100.  Since signal level values are in dBm for
this driver, max_qual->level MUST be 0, as specified in the WEXT
spec.  This patch also uses the IW_QUAL constants new in WEXT
version 17.
