ipv6: stop sending PTB packets for MTU < 1280
Reduce the attack vector and stop generating IPv6 Fragment Header for
paths with an MTU smaller than the minimum required IPv6 MTU
size (1280 byte) - called atomic fragments.
See IETF I-D "Deprecating the Generation of IPv6 Atomic Fragments" [1]
for more information and how this "feature" can be misused.

I will try.
I confirmed that v4.1.20 revert above patch is passed Section 4 No. 9 and 10
testcases
in IPv6 Ready Logo Conformance Test.
I can't immediately revert above patch from v4.6-rc1 by implementation has
changed.
is it to please a conforming test tool or fix "revert 9d289715eb5c2" a real
problem? If so: which problem do you have with 9d289715eb5c2 or
draft-ietf-6man-deprecate-atomfrag-generation-06?
Thank you for your reply.
I was wrong.
That real problem may not be 9d289715eb5c2,
Because Roy said "TAHI should be updated".
But I don't understand that real problem is in Test Tool or
draft-ietf-6man-deprecate-atomfrag-generation-06.
I am conforming it.
