freebsd-ports/sysutils/socket/files/patch-af
Edwin Groothuis d66b1112ff update to sysutils/socket: NetBSD IPv6 patches imported 
I have created a patch that can be applied to provide IPv6
	support for sysutils/socket utility. The patch imported
	from NetBSD and cleaned up to be cleanly work on FreeBSD.

PR:		ports/36202
