sky2: propogate rx hash when packet is copied
When a small packet is received, the driver copies it to a new skb to allow reusing the full size Rx buffer. The copy was propogating the checksum offload but not the receive hash information. The bug is impact was mostly harmless and therefore not observed until reviewing this area of code. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.
