ixgbe: fix possible null buffer error

2011-10-03T18:40:37+00:00

commit b811ce9104a7f7663ddae4f7795a194a103b8f90 upstream.

It seems that at least one PPC machine would occasionally give a (valid) 0 as
the return value from dma_map, this caused the ixgbe code to not work
correctly.  A fix is pending in the PPC tree to not return 0 from dma map, but
we can also fix the driver to make sure we don't mess up in other arches as
well.

This patch is applicable to all current stable kernels.

Add appropriate include for prefetch users

2011-05-23T04:41:57+00:00

After discovering that wide use of prefetch on modern CPUs
could be a net loss instead of a win, net drivers which were
relying on the implicit inclusion of prefetch.h via the list
headers showed up in the resulting cleanup fallout.  Give
them an explicit include via the following $0.02 script.

 =========================================
 #!/bin/bash
 MANUAL=""
 for i in `git grep -l 'prefetch(.*)' .` ; do
 	grep -q '' $i
 	if [ $? = 0 ] ; then
 		continue
 	fi

 	(	echo '?^#include '
 		echo .
 		echo w
 		echo q
 	) | ed -s $i > /dev/null 2>&1
 	if [ $? != 0 ]; then
 		echo $i needs manual fixup
 		MANUAL="$i $MANUAL"
 	fi
 done
 echo ------------------- 8\<----------------------
 echo vi $MANUAL
 =========================================

ixgbe: cleanup some minor issues in ixgbe_down()

2011-05-15T01:08:46+00:00

This patch cleans up two minor issues in ixgbe_down.  Specifically it
addresses the fact that the VFs should not be pinged until after interrupts
are disabled otherwise they might still get a response.  It also drops the
use of the txdctl temporary variable since the only bit we should be
writing to the TXDCTL registers during a shutdown is the flush bit.

ixgbe: Merge over-temp task into service task

2011-05-15T01:08:09+00:00

This change merges the over-temp task into the service task.  As a result
all tasklets are finally combined into once single tasklet for easier

ixgbe: Merge ATR reinit into the service task

2011-05-15T01:05:37+00:00

This change merges the ATR table reinitialization into the service task.
This is yet another opportunity to avoid any race conditions as we don't
want to be attempting to reinitialize the table during a possible reset.

In addition this change adds a counter for table reinitialization so that
it can be tracked as part of the regular statistics.

ixgbe: merge reset task into service task

2011-05-15T01:04:28+00:00

This change is meant to further help to reduce possible configuration
collisions between the various tasklets.  This change combines the device
reset with the service task.  As a result it is now not possible to be
updating the link on the device while also resetting the part.

ixgbe: Merge watchdog functionality into service task

2011-05-15T01:03:24+00:00

This patch is meant to merge the functionality of the ixgbe watchdog task
into the service task.  By doing this all link state functionality will be
controlled by a single task.  As a result the reliability of the interface
will be improved as the likelihood of any race conditions is further
reduced.
