gro: give 'hash' variable in dev_gro_receive() a less confusing name
'hash' stores not the flow hash, but the index of the GRO bucket corresponding to it. Change its name to 'bucket' to avoid confusion while reading lines like '__set_bit(hash, &napi->gro_bitmask)'. Signed-off-by: Alexander Lobakin <alobakin@pm.me> Signed-off-by: David S. Miller <davem@davemloft.net>
