[dpdk-dev] Cannot use MLX5 groups : cannot create jump action.: Operation not supported

[Tom Barbette <barbette@kth.se>]

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.

sudo ~/dpdk-skylake/x86_64-native-linuxapp-gcc/app/testpmd –l 0-3 -w 
0000:17:00.0,dv_flow_en=1 –n 6 -- -i
