From: Ido Schimmel <[email protected]> Push some sampling checks to the per-ASIC operations, as they are no longer relevant for all ASICs.
The sampling rate validation against the MPSC maximum rate is only relevant for Spectrum-1, as Spectrum-2 and later ASICs no longer use MPSC register for sampling. The ingress / egress validation is pushed down to the per-ASIC operations since subsequent patches are going to remove it for Spectrum-2 and later ASICs.
