From: Nogah Frankel Date: Fri, 25 Nov 2016 09:33:32 +0000 (+0100) Subject: mlxsw: spectrum: Use generic listener struct for rx traps X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=14eeda99c4a6b6bf92261f980bcd95f345c76b64;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git mlxsw: spectrum: Use generic listener struct for rx traps Replace the old rx listener struct definitions by the generic ones. Use the new generic registering / unregistering functions for them. Add some macros to organize the trap list. Signed-off-by: Nogah Frankel Signed-off-by: Jiri Pirko Signed-off-by: David S.
