Solved. The error was due to that NIC not having UCTX_EN enabled in the
firmware.
Maybe a less cryptic message/warning would be helpful though? DV was
enabled so I did not thought the problem could be below. A warning when
the user explicitly asks for dv_flow_en=1 but UCTX_EN is not enabled maybe?
Thanks,
Tom

Hi all,
I'm struggling to use the group feature with MLX5.
I'm using 19.08.2 for now (while
https://bugs.dpdk.org/show_bug.cgi?id=371 gets fixed).
I use the latest OFED (no inbox driver this time).
I have dv_flow_en=1, but I still get "cannot create jump action.:
Operation not supported". when I want to use the jump action or "cannot
create table: Cannot allocate memory" when trying to add a rule to table
1, all of this with testpmd but my own app does not work better.
