dpdk: correct the printing of Rx offloading flags
DPDK added new Rx checksum flags[1] to handle cases like the virtual
drivers. Current check of flags is not strict enough for flags like
RTE_MBUF_F_RX_IP_CKSUM_NONE and will always be true no matter the
checksum in packet is good or bad.
Fix this issue by comparing the result of AND operation with the
correspinding Rx checksum flags.
Before this patch, packet trace prints the offload flags as below:
Packet Offload Flags
PKT_RX_IP_CKSUM_GOOD (0x0080) IP cksum of RX pkt. is valid
PKT_RX_IP_CKSUM_NONE (0x0090) no IP cksum of RX pkt.
PKT_RX_L4_CKSUM_GOOD (0x0100) L4 cksum of RX pkt. is valid
PKT_RX_L4_CKSUM_NONE (0x0108) no L4 cksum of RX pkt.
After this patch, packet offload flags would be like:
Packet Offload Flags
PKT_RX_IP_CKSUM_GOOD (0x0080) IP cksum of RX pkt. is valid
PKT_RX_L4_CKSUM_GOOD (0x0100) L4 cksum of RX pkt. is valid
Type: fix
