    gve: Make LRO work for jumbo packets
    
    Each Rx descriptor points to a packet buffer of size 2K, which means
    that MTUs greater than 2K see multi-descriptor packets. The TCP-hood of
    such packets was being incorrectly determined by looking for a flag on
    the last descriptor instead of the first descriptor.
    
    Also fixed and progressed the version number.
