From e3afe7b75ed8f809c1473ea9b39267487c187ccb Mon Sep 17 00:00:00 2001 From: John Dykstra Date: Thu, 16 Jul 2009 05:04:51 +0000 Subject: tcp: Fix MD5 signature checking on IPv4 mapped sockets Fix MD5 signature checking so that an IPv4 active open to an IPv6 socket can succeed. In particular, use the correct address family's signature generation function for the SYN/ACK. Reported-by: Stephen Hemminger Signed-off-by: John Dykstra Signed-off-by: David S.

The "OF MDIO rework" patches removed most of the support. Instead of re-adding fixed-link stuff to the drivers, this patch adds a support function for parsing the fixed-link property and obtaining a dummy phy to match. Note: the dummy phy handling in arch/powerpc is a bit of a hack and needs to be reworked. This function is being added now to solve the regression in the Ethernet drivers, but it should be considered a temporary measure until the fixed link handling can be reworked.
