The Broadcom driver produces the following compilation warning
drivers/infiniband/hw/bnxt_re/ib_verbs.c:
	In function ‘bnxt_re_create_ah’:
drivers/infiniband/hw/bnxt_re/ib_verbs.c:668:6:
	warning: variable ‘vlan_tag’ set but not used [-Wunused-but-set-variable]

Let's remove it till vlan_tag will be implemented properly.
