[ Upstream commit 11ba961c916127651e12af6cad3891f8aeb25aa9 ]
It was noticed that NIC always pass all multicast traffic to the host regardless of IFF_ALLMULTI flag on the interface. The rule in MC Filter Table in NIC, that is configured to accept any multicast packets, is turning on if IFF_MULTICAST flag is set on the interface. It leads to passing all multicast traffic to the host. This fix changes the condition to turn on that rule by checking IFF_ALLMULTI flag as it should.
