Some NICs share resources like packet filters across
multiple interfaces they support. From HW point of view
it is possible to use all filters for a single interface.
Currently ethtool doesn't support modifying filter count so
that user can allocate more filters to a interface and less
to others. This patch adds ETHTOOL_SRXCLSRLCNT ioctl command
for modifying filter count.

example command:
./ethtool -U eth0 rule-count 256

man devlink-resource ?
