Commit Message

Satheesh Paul Antonysamy June 22, 2022, 1:22 a.m. UTC
From: Satheesh Paul <psatheesh@marvell.com>

Added support to create flow rules with count, mark and
security actions and mark pattern.

Signed-off-by: Satheesh Paul <psatheesh@marvell.com>
---
v5:
* Rebased the patch.
v4:
* Added more description in documenation for flow rule options.
v3:
