SFT init failed

When I was trying to run the doca url filter on host through vf.

The Trouble shooting give suggestion this error below may be relevant to too many cores.
sudo ./doca_url_filter -a 01:00.0 -a 0000:01:00.3 -a 0000:01:00.4 -l 0,1 – -p

But when I do this -l 0

It suggests this way. Can anyone help?

After trying, I set the running command as :
./doca_url_filter -a 0000:01:00.3,class=regex:eth,representor=[196609],sft_en=0 -a 0000:01:00.4,class=regex:eth,representor=[196610],sft_en=0 -l 0-7 – -p

And now the new error is :

Help please!
