Patch has been applied to the master branch, backported to release/2.5
(leaving out the mss.c hunks, and the syshead.h one still has HAVE_IPVEC
to remove...) and to release/2.4 (sys/poll.h in configure.ac).
Verified that 2.5 and 2.4 show the right socket error message
("write UDPv4 [EMSGSIZE Path-MTU=800]"), which is what this bugfix
is fixing - have not verified that the old frame/MTU code actually
works, but I suspect we never managed to break it.
Note: this fixes --mtu-disc over IPv4 transport. IPv6 transport returns
"extended error messages" now as well, but now the handler seems to expect
something else, and does not recognize this as "mtu". Will address this
in the next patch.
