DNS filter failed on Bluefield-2

Running dns filter application with two SF ports failed with “Cannot create HWS action since HWS is not suported”.

The command to run is “/opt/mellanox/doca/applications/dns_filter/bin/doca_dns_filter -a auxiliary:mlx5_core.sf.2,dv_flow_en=2 -a auxiliary:mlx5_core.sf.3,dv_flow_en=2 – -l 60 -p 03:00.0 --rules /tmp/regex_rules.rof2.binary --type allow”


You can try the below:

  1. make sure that the SF are trusted.
  2. try to : systemctl restart mlx-regex
