pch_gbe: memory corruption calling pch_gbe_validate_option()

2012-05-21T16:40:06+00:00

commit 73f98eab9b9e0bab492ca06add5657d9e702ddb1 upstream.

pch_gbe_validate_option() modifies 32 bits of memory but we pass
&hw->phy.autoneg_advertised which only has 16 bits and &hw->mac.fc
which only has 8 bits.

pch_gbe: Do not abort probe on bad MAC

2012-05-21T16:40:06+00:00

commit 2b53d07891630dead46d65c8f896955fd3ae0302 upstream.

If the MAC is invalid or not implemented, do not abort the probe. Issue
a warning and prevent bringing the interface up until a MAC is set manually
(via ifconfig $IFACE hw ether $MAC).

Tested on two platforms, one with a valid MAC, the other without a MAC. The real
MAC is used if present, the interface fails to come up until the MAC is set on
the other. They successfully get an IP over DHCP and pass a simple ping and
login over ssh test.

This is meant to allow the Inforce SYS940X development board:
http://www.inforcecomputing.com/SYS940X_ECX.html
(and others suffering from a missing MAC) to work with the mainline kernel.
Without this patch, the probe will fail and the interface will not be created,
preventing the user from configuring the MAC manually.

This does not make any attempt to address a missing or invalid MAC for the
pch_phub driver.

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

PCH_GbE : Fixed the issue of collision detection

2011-05-09T18:55:15+00:00

The collision detection setting was invalid.
When collision occurred, because data was not resent,
there was an issue to which a transmitting throughput falls.

This patch enables the collision detection.
