[dpdk-dev,v2,2/4] mbuf:change PKT_TX_IPV4 and PKT_TX_IPV6 definition
Commit Message
It will avoid to send a packet with a bad info:
- we receive a Ether/IP6/IP4/L4/data packet
- the driver sets PKT_RX_IPV6_HDR
- the stack decapsulates IP6
- the stack sends the packet, it has the PKT_TX_IPV6 flag but it's an IPv4 packet.
