FreeBSD NFS server not responding to TCP SYN packets from Linux/SunOS clients

[Jim Rees]

There was a bug in the FreeBSD v3 client that it didn't retransmit at all,
even after a reconnect.  I fixed that in rev 1.125 of nfs_socket.c.  It
should now retransmit exactly once.  That could of course result in a replay
at the server, depending on what caused the reconnect.  In the case where
the server drops the connection due to inactivity, I think there is no
replay.
