selftests/net: packetdrill: add tcp_syncookies_ip[46]_9k
These tests check syncookie mode is able to reconstruct some
client options when TCP TS are used:
- wscale option.
- sackOK.
- MSS (in a limited way, especially for IPv4).
- ECN : not enabled.
Note that IPv4 and IPv6 have different msstab[] values:
IPv4 msstab[4] = { 536, 1300, 1440, 1460 }
IPv6 msstab[4] = { 1280 - 60, 1480 - 60, 1500 - 60, 9000 - 60 }
IPv4 is currently capping SND_MSS to 1460, even on a 9K MTU network.
