From: Ido Schimmel Date: Mon, 22 Mar 2021 15:58:53 +0000 (+0200) Subject: mlxsw: spectrum_router: Create per-ASIC router operations X-Git-Tag: accepted/tizen/unified/20230118.172025~7335^2~439^2~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d354fdd923e7a3dc2f5c34cfcfb0401bd8c56ea8;p=platform%2Fkernel%2Flinux-rpi.git mlxsw: spectrum_router: Create per-ASIC router operations There are several differences in the router module between Spectrum-1 and Spectrum-{2,3}. Currently, this is only apparent in the router interface (RIF) operations that are split between these ASICs. A subsequent patch is going to introduce another difference between these ASICs. Create per-ASIC router operations that will encapsulate all these differences. For now, these operations are only used to set the per-ASIC RIF operations in 'mlxsw_sp->router->rif_ops_arr'. Note that this fields was unused since commit 1f5b23033937 ("mlxsw: spectrum: Set RIF ops per ASIC type"). Signed-off-by: Ido Schimmel Reviewed-by: Petr Machata Signed-off-by: David S.
