Subject: [PATCH] net/igb: fix checksum valid flags

[ upstream commit 760110abd68d84014b48bb84945276016d3e7616 ]

To enable L4 checksum offload for SCTP packets, E1000_RXCSUM_CRCOFL
should be set.

Otherwise, for SCTP packets even L4 checksum not calculated, it will
return PKT_RX_L4_CKSUM_GOOD.

Fixes: af75078fece3 ("first public release")
