Subject: [PATCH v3 19/20] tcp: Add HOSTSIDE(x), HOSTFLOW(x) macros
Date: Fri, 31 Jan 2025 20:39:52 +0100 [thread overview]
Message-ID: <20250131193953.3034031-20-sbrivio@redhat.com> (raw)
In-Reply-To: <20250131193953.3034031-1-sbrivio@redhat.com>
Those are symmetric to TAPSIDE(x)/TAPFLOW(x) and I'll use them in
the next patch to extract 'oport' in order to re-bind sockets to
the original socket-side local port.
