From e4ac43200fd6b8b8de3b487e74e74d3742f70d79 Mon Sep 17 00:00:00 2001 From: Holger Eitzenberger Date: Fri, 26 Dec 2008 13:40:48 -0800 Subject: [PATCH] 802.3ad: generalize out mac address initializer Generalize out mac address initializer for the LACPDU multicast address and use in two places. Remove the now unused AD_MULTICAST_LACPDU_ADDR. Signed-off-by: Holger Eitzenberger Signed-off-by: David S.
