e1000e: disable broken PHY wakeup for ICH10 LOMs, use MAC wakeup instead

2011-03-02T11:34:27+00:00

When support for 82577/82578 was added[1] in 2.6.31, PHY wakeup was in-
advertently enabled (even though it does not function properly) on ICH10
LOMs.  This patch makes it so that the ICH10 LOMs use MAC wakeup instead
as was done with the initial support for those devices (i.e. 82567LM-3,
82567LF-3 and 82567V-4).

e1000e: flush all writebacks before unload

2011-02-17T09:11:21+00:00

The driver was not flushing all writebacks before unloading, possibly
causing memory to be written by the hardware after the driver had
reinitialized the rings.

This adds missing functionality to flush any pending writebacks and is
called in all spots where descriptors should be completed before the driver
begins processing.

e1000e: check down flag in tasks

2011-02-17T08:45:06+00:00

This change is part of a fix to avoid any tasks running while the driver is
exiting and deinitializing resources.

e1000e: tx_timeout should not increment for non-hang events

2011-02-08T09:10:17+00:00

Currently the driver increments the tx_timeout counter (an error counter)
when simply resetting the part with outstanding transmit work pending.
This is an unnecessary count of an error, when all we should be doing is
just resetting the part and discarding the transmits.  With this change the
only increment of tx_timeout is when the stack calls the watchdog reset
function due to a true Tx timeout.

e1000e: power off PHY after reset when interface is down

2011-01-10T07:44:09+00:00

Some Phys supported by the driver do not remain powered off across a reset
of the device when the interface is down, e.g. on 82571, but not on 82574.
This patch powers down (only when WoL is disabled) the PHY after a reset if
the interface is down and the ethtool diagnostics are not currently running.

The ethtool diagnostic function required a minor re-factor as a result, and
the e1000_[get|put]_hw_control() functions are renamed since they are no
longer static to netdev.c as they are needed by the ethtool diagnostics.
A couple minor whitespace issues were cleaned up, too.
