    Subject[PATCH 4.14 09/29] net: aquantia: Fix IFF_ALLMULTI flag functionality
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Dmitry Bogdanov <dmitry.bogdanov@aquantia.com>

    [ 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.

    Fixes: b21f502f84be ("net:ethernet:aquantia: Fix for multicast filter handling.")
