[PATCH 4.19 38/42] mlxsw: spectrum: Fix IP2ME CPU policer configuration

[Greg Kroah-Hartman]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Shalom Toledo <shalomt@xxxxxxxxxxxx>

[ 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.
