From 00acda68b587181546d68fb98db1c5c73ee6c16f Mon Sep 17 00:00:00 2001 From: Steve Glendinning Date: Fri, 2 Nov 2012 00:44:20 +0000 Subject: [PATCH] smsc95xx: fix tx checksum offload for big endian f7b2927 introduced tx checksum offload support for smsc95xx, and enabled it by default. This feature doesn't take endianness into account, so causes most tx to fail on those platforms. This patch fixes the problem fully by adding the missing conversion. An alternate workaround is to disable TX checksum offload on those platforms. The cpu impact of this feature is very low. Signed-off-by: Steve Glendinning Signed-off-by: David S.
