From 7e56cac4b68805470849ba373dd313ba0e7cdb81 Mon Sep 17 00:00:00 2001 From: Sucheta Chakraborty Date: Mon, 4 Oct 2010 04:20:13 +0000 Subject: [PATCH] qlcnic: fix vlan TSO on big endian machine o desc->vlan_tci is in __le16 format. Doing htons and cpu_to_le64 again on vlan_tci, result in invalid value on ppc. Signed-off-by: Sucheta Chakraborty Signed-off-by: Amit Kumar Salecha Signed-off-by: David S.
