The fields of L2TPv2 common header were reversed in big endian and
little endian.
This patch fixes this error to ensure L2TPv2 can be parsed correctly.
Fixes: 3a929df1f286 ("ethdev: support L2TPv2 and PPP procotol")

This patch adds L2TPv2 control message and 5 types of data message
support for testpmd.
The added L2TPv2 message types are listed below:
1. L2TPv2 control
2. L2TPv2
3. L2TPv2 + length option
4. L2TPv2 + sequence option
5. L2TPv2 + offset option
6. L2TPv2 + length option + sequence option

Add support for PPP over L2TPv2 over UDP protocol and L2TPv2
protocol RSS hash based on outer MAC src address and L2TPv2
session ID.
Patterns are listed below:
eth/ipv4/udp/l2tpv2
eth/ipv4/udp/l2tpv2/ppp
eth/ipv6/udp/l2tpv2
eth/ipv6/udp/l2tpv2/ppp
