Subject: [PATCH] generic: b53: clear SM_SW_FWD_MODE unconditionally when
enabling VLAN
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Setting this bit stops BCM53125 (bgmac actually) from receiving any
packets. This bit is cleared conditionally in b53_switch_reset and it
seems the same is done in bcmrobo.c which never sets that bit again.
