4.17-stable review patch. If anyone has any objections, please let me know.


From: Dmitry Bogdanov <dmitry.bogdanov@xxxxxxxxxxxx>

[ 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.
