    qede: Support XDP adjustment of headers · 059eeb07
    Mintz, Yuval authored
    In case an XDP program is attached, reserve XDP_PACKET_HEADROOM
    bytes at the beginning of the packet for the program to play
    with.
    
    Modify the XDP logic in the driver to fill-in the missing bits
    and re-calculate offsets and length after the program has finished
    running to properly reflect the current status of the packet.
    
    We can then go and remove the limitation of not supporting XDP programs
    where xdp_adjust_head is set.
