Great.

My minor suggestions (you can ignore them :-))

from
"Number of filters addition events that do not change the number of free"
to
"Number of failed filter addition events"

(I believe, "do not change the number of free" part is given when addition
is failing)

from
 "Number of packets that missed matched any flow director filter"
to
"Number of packets that didn't match any flow director filter"

As we talked on another thread, yes, problem is just the counter not
getting updated. The functionality is fine.


 Appreciate your awesome work.
