From 6460d948f3ebf7d5040328a60a0ab7221f69945b Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Sat, 14 Jul 2007 19:07:52 -0700 Subject: [NET]: Add ethtool support for NETIF_F_IPV6_CSUM devices. Add ethtool utility function to set or clear IPV6_CSUM feature flag. Modify tg3.c and bnx2.c to use this function when doing ethtool -K to change tx checksum.
