From 34a277212c67a395b47b715aa89c4b4e2c957d42 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Thu, 11 Mar 2021 14:24:15 +0200 Subject: [PATCH] mlxsw: spectrum_trap: Split sampling traps between ASICs Sampling of ingress packets is supported using a dedicated sampling mechanism on all Spectrum ASICs. However, Spectrum-2 and later ASICs support more sophisticated sampling by mirroring packets to the CPU. As a preparation for more advanced sampling configurations, split the trap configuration used for sampled packets between Spectrum-1 and later ASICs. This is needed since packets that are mirrored to the CPU are trapped via a different trap identifier compared to packets that are sampled using the dedicated sampling mechanism.
