Subject: fix for TCP "protocol not supported" problem
Date: 28 Nov 1992 14:54:00 GMT

Yesterday I mentioned the bug in net/tcp/sock.c which prevents
programs which supply a protocol argument of PF_INET to the socket(2)
call from working.

Here is the patch to sock.c which I promised; it should enable you to
port TCP programs more easily.

Ian.
