This traffic should not be subjected to Suricata inspection, as am using inline, so what would be the best way to suppress that ?

In general, check
https://redmine.openinfosecfoundation.org/projects/suricata/wiki/Ignoring_Traffic
 Note that BPF won't work in inline mode.

I'd imagine a rule like "pass ip any any -> any any (ip_proto:47; ...)

If you run the iptables/nfq based inline method you can also use
iptables to control which part of the traffic is inspected by Suri.
