Subject: [patch net-next 05/19] mlxsw: switchx2: Use generic listener struct for rx traps
Date: Fri, 25 Nov 2016 10:33:33 +0100	[thread overview]
Message-ID: <1480066427-3961-6-git-send-email-jiri@resnulli.us> (raw)
In-Reply-To: <1480066427-3961-1-git-send-email-jiri@resnulli.us>

From: Nogah Frankel <nogahf@mellanox.com>

Reorganize the traps to use the new generic listener struct and
functions. Use macros to shorten the traps list.
