From: Sunil Kumar Kori <redacted> Implement API to enable or disable meter instance for CNXK platform. Signed-off-by: Sunil Kumar Kori <redacted> Signed-off-by: Rakesh Kudurumalla <redacted> --- 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 drivers/net/cnxk/cnxk_ethdev_mtr.c | 60 ++++++++++++++++++++++++++++++ 1 file changed, 60 insertions(+)
