[PATCH net-next 1/2] net: dsa: lan9303: Set up trapping of IGMP to CPU port

2017-11-10 Thread Egil Hjelmeland
IGMP packets should be trapped to the CPU port. The SW bridge knows whether to forward to other ports. With "IGMP snooping for local traffic" merged, IGMP trapping is also required for stable IGMPv2 operation. LAN9303 does not trap IGMP packets by default. Enable IGMP trapping in lan9303_setup.
