From 3b140a678834f55602e50e7d6a47663e230434a7 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Thu, 26 Jun 2014 10:06:44 -0700 Subject: [PATCH] net: systemport: do not clear IFF_MULTICAST flag The SYSTEMPORT Ethernet MAC supports multicast just fine, it just lacks any sort of Unicast/Broadcast/Multicasting filtering at the Ethernet MAC level since that is handled by the front end Ethernet switch, but that is properly handled by bcm_sysport_set_rx_mode(). Some user-space applications might be relying on the presence of this flag to prevent using multicast sockets, this also prevents that interface from joining the IPv6 all-router mcast group.
