Subject: [PATCH v2 0/2] Support ethtool ntuple rule count change
Date: Fri, 23 Jul 2021 23:46:44 +0530	[thread overview]
Message-ID: <1627064206-16032-1-git-send-email-sgoutham@marvell.com> (raw)

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.
