[dpdk-dev] [PATCH] net/enic: set L4 checksum flags for IPv6 packets

[John Daley]

From: Hyong Youb Kim <hyonkim at cisco.com>

enic_cq_rx_to_pkt_flags() currently sets checksum good/bad flags only
for IPv4.  The hardware actually validates the TCP/UDP checksum of
IPv6 packets too. Set PKT_RX_L4_CKSUM_{GOOD,BAD} accordingly.
