From 20ffb64d6f8f4dc93952f90142107f31d4298161 Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Wed, 12 Mar 2014 11:28:19 +0100 Subject: eth: fec: Fix lost promiscuous mode after reconnecting cable [ Upstream commit 84fe61821e4ebab6322eeae3f3c27f77f0031978 ] If the Freescale fec is in promiscuous mode and network cable is reconnected then the promiscuous mode get lost. The problem is caused by a too soon call of set_multicast_list to re-enable promisc mode. The FEC_R_CNTRL register changes are overwritten by fec_restart. This patch fixes this by moving the call behind the init of FEC_R_CNTRL register in fec_restart. Successful tested on a i.MX28 board. Signed-off-by: Stefan Wahren Signed-off-by: David S.
