Subject: mlxsw: spectrum: Use dedicated trap group for sampled packets
Patch-mainline: v5.8-rc1
Git-commit: ce3c3bf0bfad4bb8652f3c3f5770d38a10ce2894
References: bsc#1176774
The rate with which packets are sampled is determined by user space, so
there is no need to associate such packets with a policer.
