I am running this with the ixgbetool patch you have and only 1 issue I've
seen so far: fdirustat_add increments on adding a filter but
fdirustat_remove does not on deleting one (if thats how its supposed to
work)

Can you please populate "description" for all the sysctls you are adding?
:-)

Cheers,
