Flowtable HW offload crash on supported hardware?

Hi,

It seems trying to use hardware offload with flowtables in 1.5x has some issues. I’m testing with an intel e810, which supports hw-tc-offload. On the latest nightly:

set interfaces ethernet eth0 offload hw-tc-offload
set interfaces ethernet eth1 offload hw-tc-offload
set firewall flowtable FT1 offload hardware
commit

Unknown firewall error detected: /run/nftables.conf:21:15-32: Error:
Could not process rule: Operation not supported     flowtable
VYOS_FLOWTABLE_FT1 {               ^^^^^^^^^^^^^^^^^^
/run/nftables.conf:106:15-32: Error: Could not process rule: Operation
not supported     flowtable VYOS_FLOWTABLE_FT1 {
^^^^^^^^^^^^^^^^^^

[[firewall]] failed

We have a bug report T6526
Try the same on the Debian and open a bug report to the Netfilter https://bugzilla.netfilter.org/
I guess hardware offload is not implemented correctly for most NICs, it is a question for the netfilter guys.
