src: add ecn support
This supports both IPv4:
# nft --debug=netlink add rule ip filter forward ip ecn ce counter
ip filter forward
[ payload load 1b @ network header + 1 => reg 1 ]
[ bitwise reg 1 = (reg=1 & 0x00000003 ) ^ 0x00000000 ]
[ cmp eq reg 1 0x00000003 ]
[ counter pkts 0 bytes 0 ]
For IPv6:
# nft --debug=netlink add rule ip6 filter forward ip6 ecn ce counter
ip6 filter forward
[ payload load 1b @ network header + 1 => reg 1 ]
[ bitwise reg 1 = (reg=1 & 0x00000030 ) ^ 0x00000000 ]
[ cmp eq reg 1 0x00000030 ]
[ counter pkts 0 bytes 0 ]
