Subject: [PATCH v4 09/10] tcp: remove tap_hdr parameter
Date: Fri, 31 May 2024 16:23:43 +0200 [thread overview]
Message-ID: <20240531142344.1420034-10-lvivier@redhat.com> (raw)
In-Reply-To: <20240531142344.1420034-1-lvivier@redhat.com>
As tap_hdr is not used with vhost-user, remove it from tcp_fill_headers4()
and tcp_fill_headers6()
Signed-off-by: Laurent Vivier <lvivier@redhat.com>
