    net: flow: Add l3mdev flow update · 9ee0034b

    Add l3mdev hook to set FLOWI_FLAG_SKIP_NH_OIF flag and update oif/iif
    in flow struct if its oif or iif points to a device enslaved to an L3
    Master device. Only 1 needs to be converted to match the l3mdev FIB
    rule. This moves the flow adjustment for l3mdev to a single point
    catching all lookups. It is redundant for existing hooks (those are
    removed in later patches) but is needed for missed lookups such as
    PMTU updates.
