    Subject[PATCH 4.14 05/62] ixgbe: fix MAC anti-spoofing filter after VFLR
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

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

    [ Upstream commit 6702185c1ffec3421181b5e24491e3fac920cb61 ]

    This change resolves a driver bug where the driver is logging a
    message that says "Spoofed packets detected". This can occur on the PF
    (host) when a VF has VLAN+MACVLAN enabled and is re-started with a
    different MAC address.

    MAC and VLAN anti-spoofing filters are to be enabled together.
