====================
mlxsw: Various fixes

Patch #1 fixes wrong invocation of mausezahn in a couple of selftests.
The tests started failing after Fedora updated their libnet package from
version 1.1.6 to 1.2.1. With the fix the tests pass regardless of libnet
version.

Patch #2 fixes an issue in the mirroring to CPU code that results in
policer configuration being overwritten.
