From: Ido Schimmel Date: Mon, 4 Jul 2016 06:23:15 +0000 (+0200) Subject: mlxsw: spectrum: Unsplit the vFID range X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3ba2ebf4a2cbcf42fe471146d9d668865caa9f21;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git mlxsw: spectrum: Unsplit the vFID range Previous commit deprecated the vFIDs used to get traffic to the CPU ('port_vfids'). Thus, we now use the vFIDs as god intended and the artificial split is no longer needed. Rename functions and variables to reflect that.
