[dpdk-dev] [PATCH v4 10/28] common/cnxk: support RoC API to connect bandwidth profiles

[skori]

From: Sunil Kumar Kori <sk...@marvell.com>

To maintain chain of bandwidth profiles, they needs to be
connected. Implement RoC API to connect two bandwidth profiles
at different levels.

v4:
 - Rebase support on dpdk-next-net-mrvl branch
 - Handled meter action during flow destroy
 - Handled meter cleanup during port shutdown
 
v3:
 - Rebase support on latest DPDK
 - Handled multilevel chaining for tree hierarchy
 - Fix naming convention
v2:
 - Rebase support on latest DPDK
 - Handled multilevel chaining for linear hierarchy
 - Review comments incorporated
