[dpdk-dev] [PATCH] net/e1000: fix checksum valid flags error

[Wei Zhao]

This problem is caused by a missing set of E1000_RXCSUM_CRCOFL
in eth_igb_rx_init(), it should be set to enable SCTP packet
L4 checksum.If it is not set, the printf message in cksum fwd
about L4 SCTP cksum flag is error.

Fixes: d15fcf76c8b7 ("net/e1000: move to drivers/net/")
