--- Comment #1 from Michael Tuexen <tuexen@freebsd.org> ---
I would be interested why an application wants to use a SOCK_SEQPACKET packet
and also expects message loss when providing a too small receive buffer?
From my understanding SOCK_SEQPACKET and SOCK_STREAM are both reliable.
For me it looks like the description of recvmsg() is missing a differentiation
between SOCK_DGRAM and SOCK_SEQPACKET.
