[PATCH] net/ice: add devargs for disabling mac filter

[Zhang, Ke1X]

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
