[v2,0/2] Support ethtool ntuple rule count change

Message

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.
This 2 patch series adds support to modify ntuple rule
count for OcteonTx2 netdev.

Changes from v1:
   * No changes in code.
   * Previous discussion didn't conclude, submiting patches again to revive it.
   * Jakub suggested if devlink-resource can be used for this.
   * But since ntuple rule insert and delete are part of ethtool,
     I thought having this config also in ethtool makes sense ie
     all ntuple related stuff within one tool.
   * Also number of MCAM entries can be changed at runtime
     without a driver reload.
