   4 Subject: [PATCH 14/56] sky2: propogate rx hash when packet is copied
   5
   6 [ Upstream commit 3f42941b5d1d13542b1a755a9e4f633aa72e4d3e ]
   7
   8 When a small packet is received, the driver copies it to a new skb to allow
   9 reusing the full size Rx buffer. The copy was propogating the checksum offload
  10 but not the receive hash information. The bug is impact was mostly harmless
  11 and therefore not observed until reviewing this area of code.
