Subject: [PATCH 3.14 77/94] mlx4_core: Fix incorrect FLAGS1 bitmap test in mlx4_QUERY_FUNC_CAP

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jack Morgenstein <jackm@....mellanox.co.il>

commit bc82878baa10c2a6a4a6affaf52c152935112142 upstream.

Commit eb17711bc1d6 ("net/mlx4_core: Introduce nic_info new flag in
QUERY_FUNC_CAP") did:

	if (func_cap->flags1 & QUERY_FUNC_CAP_FLAGS1_OFFSET) {

which should be:

	if (func_cap->flags1 & QUERY_FUNC_CAP_FLAGS1_FORCE_VLAN) {

Fix that.

Fixes: eb17711bc1d6 ("net/mlx4_core: Introduce nic_info new flag in QUERY_FUNC_CAP")
