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 ?

Since ntuple rule insert and delete are part of ethtool, I thought having this config also in
ethtool will make user life easy ie all ntuple related stuff within one tool.

Thanks,
Sunil.
