The code says that the maximum packet size is 131024, but in reality
it's 65527. Values greater than 65527 will cause ping6 to fail:
$ ping6 -s 100000 ::1
PING6 ::1 (::1): 100000 data bytes
ping6: sendmsg: Invalid argument
ping6: wrote ::1 100008 chars, ret=-1
Document the maximum as 65527, discussed with florian@.
Also re-break lines so that the formatting of the identical text matches
ping.8.
