Hi Stephen:
Thanks for your comments.
I just follow the definition of other variables like pipe_mode_support,
safe_mode_support.
And when I run the testpmd , I could write the command like this:
./dpdk-testpmd -l 16-32 -a ca:00.0,mac-filter-disable=1 -a ca:00.1 -- -i
The value could 1 or 0.
Would you please give me some guidance about the definition of the variable?
BR
