- The TCP connection stays alive. This should not be the case since r303626 (D7272). Fixed in r307726 (D7904).
- The reception is handled by FreeBSD as a hard error, allthough neither specified as a soft or hard error RFC1122.
- The reception is handled by FreeBSD as a hard error, allthough specified in RFC1122 as a soft error.
- An incoming PTB packet results in an adapted MSS for IPv6, but not for IPv4.
