Subject: [nftables 0.9.2 | flow table] check whether it works?
Date: Sun, 22 Mar 2020 14:18:52 +0000	[thread overview]
Message-ID: <41317d5f-a0b4-da4e-356b-45cf7677cf15@gmx.net> (raw)

How it is possible to check whether flowtable offloading actually works?

Can the populated flowtables somehow be dumped / observed / monitored?

If not mistaken the conntrack table would exhibit the [OFFLOAD] label
but observing the conntack table it does not show such label.

Reading https://lwn.net/Articles/738214/:

This node running OpenWrt with Marvell Armada 385 88F6820 (that
supposedly features Accelerated Data Path) with integrated NIC plus an
onboard Marvell 88E6176 switch, latter driven by DSA, I am wondering
whether flowtables offloading is even expected to work in such setup?
