    skbuff: Rename 'offload_mr_fwd_mark' to 'offload_l3_fwd_mark' · 875e8939

    Commit abf4bb6b ("skbuff: Add the offload_mr_fwd_mark field") added
    the 'offload_mr_fwd_mark' field to indicate that a packet has already
    undergone L3 multicast routing by a capable device. The field is used to
    prevent the kernel from forwarding a packet through a netdev through
    which the device has already forwarded the packet.
    
    Currently, no unicast packet is routed by both the device and the
    kernel, but this is about to change by subsequent patches and we need to
    be able to mark such packets, so that they will no be forwarded twice.
    
    Instead of adding yet another field to 'struct sk_buff', we can just
    rename 'offload_mr_fwd_mark' to 'offload_l3_fwd_mark', as a packet
    either has a multicast or a unicast destination IP.
    
    While at it, add a comment about both 'offload_fwd_mark' and
    'offload_l3_fwd_mark'.
