tg3: Fix stats for 5704 and later devices

2011-05-19T22:00:00+00:00

Commit 4d95847381228639844c7197deb8b2211274ef22, entitled
"tg3: Workaround rx_discards stat bug" modified the hardware statistics
data structure.  The modification shifted the statistics so that the
labels no longer corresponded to the counter values.  This patch fixes
the problem by utilizing reserved space for the new counters.

tg3: Fix EEE interoperability workaround

2011-05-19T22:00:00+00:00

Commit 21a00ab270f95d32e502d92f166dd75c518d3c5f, entitled
"tg3: Fix EEE interoperability issue", added an EEE interoperability
fix.  We found that the fix doesn't work if applied too early though.
This patch delays the fix until right before allowing LPI assertion.

tg3: Fix 57765 B0 data corruption

2011-05-19T22:00:00+00:00

The PCIe max FTS limit is too aggressive on these chips.  This patch
loosens the limit a little to eliminate data corruption issues.

tg3: Convert u32 flag,flg2,flg3 uses to bitmap

2011-04-28T20:42:24+00:00

Using a bitmap instead of separate u32 flags allows a consistent, simpler
and more extensible mechanism to determine capabilities.

Convert bitmasks to enum.
Add tg3_flag, tg3_flag_clear and tg3_flag_set.
Convert the flag & bitmask tests.

tg3: Fix int generation hw bug for 5719 / 5720

2011-04-26T07:07:01+00:00

On the 5719 and 5720, there is a bug where the hardware will
misinterpret a status tag update and leave interrupts permanently
disabled.  This patch enables a hardware fix that works around the
issue.

tg3: Adjust rx prod ring bd replenish thresholds

2011-04-22T00:05:55+00:00

The oldest tg3 devices had large rx producer ring BD caches.  Back then,
it made sense to make the BD cache replenish threshold only a function
of the number of rx buffers posted by the driver.  Since then, the BD
cache sizes have shrunk to 25% of their original size and, in some
cases, the ring sizes have quadrupled in size.  Under such conditions,
static BD cache replenish thresholds no longer match the hardware
constraints.

This patch attempts to factor in the BD cache size into the bd cache
replenish strategy, taking the existing hardware bugs into account.

tg3: Workaround rx_discards stat bug

2011-04-22T00:05:54+00:00

The 5717, 5718, 5719 A0, and 5720 A0 has a bug where the rx_discards
statistic counter will increment when dropping unwanted multicast
frames.  This patch works around the problem by attempting to
recreate the data using other means.  The resulting value will not be
accurate, but it can still serve as a problem indicator.

tg3: Add support for extended VPD blocks

2011-04-14T00:10:08+00:00

In some devices, the VPD block is relocated to a different area in
NVRAM.  The original location can still contain old, but still valid VPD
data.  This patch changes the code to look for an extended VPD block in
NVRAM.  If one is found, that block is used for all VPD operations
instead.
