Uhh.. I wanted to say "just use tc -json ... | jq ..." to avoid all this
parsing, but the action police doesn't support it yet. :-(

This ties back to my previous email. Is 1280b really what is expected
here? (for both flavors)
If 100K was kept as 100K, seems 'K' is what is wanted.
Then, the burst would be 1250b.
While reading the code on this, now noticed that in
netdev_dpdk_policer_construct() it uses 1000 for both.
Anyhow, good that this is now getting asserted.
Other than this and comments already made by Tonghao Zhang, I have no
further comments.
Thanks,
Marcelo
