Subject: [PATCH net-next 0/2] net: sched: act_tunnel_key: UDP checksums
Date: Wed, 14 Jun 2017 21:19:29 +0200	[thread overview]
Message-ID: <cover.1497467840.git.jbenc@redhat.com> (raw)

Currently, the tunnel_key tc action does not set TUNNEL_CSUM, thus
transmitting packets with zero UDP checksum. This is inconsistent with how
we treat non-lwt UDP tunnels where the default is to fill in the UDP
checksum. Non-zero UDP checksum is the better default anyway for various
reasons previously discussed.

Make this configurable for the tunnel_key tc action with the default being
non-zero checksum. Saves a lot of surprises especially with IPv6.
