Subject: Mark IP protocol GRE as MP safe from socket layer.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=093b188bc00a9b5cda68a9479c7b8d38c0c9d621;p=openbsd

Mark IP protocol GRE as MP safe from socket layer.

The pipex code in gre_send() matches more or less what udp_send()
does.  This has been MP safe for a long time.  rip_send() is already
called with PR_MPSOCKET.

OK mvs@
