I guess the TCP options being under "ipv4"

if you use IPv6.
My understading was that the IPv4 & IPv6 stacks are completely separate
-- code & function.
Given the long list of separate, IPv6-specific, other-than-tcp sysctls,
shared tcp tuning parameters seems odd.
Digging in as close to authoritative Docs for it as I've been able to
yet find, it seems that your point *is*, in fact, posed ... but as what
appears to be a question
Variables:IPv6 has no global variables such as tcp_*. tcp_* settings
under ipv4/ alsoapply to IPv6 [XXX?].
There's also this very recent proposal
from Jiri Bohac @ SUSE Labs, Suse CZ, which proposes to introduce
separate sysctls for tcp_syncookies_mss_table in *separate* net.ipv4 &
net.ipv6 namespaces. He's a contributor to this list & a kernel dev as
well ... perhaps he might shed some additional light.
Perhaps that's "coming", rather than "is" ...
