    sfc: Replace LRO with GRO · da3bc071

    This patch makes sfc invoke the GRO hooks instead of LRO.  As
    GRO has a compatible external interface to LRO this is a very
    straightforward replacement.
    
    Everything should appear identical to the user except that the
    offload is now controlled by the GRO ethtool option instead of
    LRO.  I've kept the lro module parameter as is since that's for
    compatibility only.
    
    I have eliminated efx_rx_mk_skb as the GRO layer can take care
    of all packets regardless of whether GRO is enabled or not.
    
    So the only case where we don't call GRO is if the packet checksum
    is absent.  This is to keep the behaviour changes of the patch to
    a minimum.
