| Subject: mlxsw: spectrum: Fix IP2ME CPU policer configuration |
| |
| From: Shalom Toledo <shalomt@mellanox.com> |
| |
| [ Upstream commit 96801552f846460fe9ac10f1b189602992f004e1 ] |
| |
| The CPU policer used to police packets being trapped via a local route |
| (IP2ME) was incorrectly configured to police based on bytes per second |
| instead of packets per second. |
| |
| Change the policer to police based on packets per second and avoid |
| packet loss under certain circumstances. |
| |
| Fixes: 9148e7cf73ce ("mlxsw: spectrum: Add policers for trap groups") |
