From 65565884fba67d9254f32d239b0fb6c38fae88aa Mon Sep 17 00:00:00 2001 From: Merav Sicron Date: Tue, 19 Jun 2012 07:48:26 +0000 Subject: [PATCH] bnx2x: Make the transmission queues adjacent In the current scheme the transmission queues of traffic-class 0 were 0-15, the transmission queues of traffic-class 1 were 16-31 and so on. If the number of RSS queues was smaller than 16, there were gaps in transmission queues numbering, as well as in CIDs numbering. This is both a waste (especially when 16 is increased to 64), and may causes problems with flushing queues when reducing the number of RSS queues (using ethtool -L). The new scheme eliminates the gaps. Signed-off-by: Merav Sicron Signed-off-by: Eilon Greenstein Signed-off-by: David S.
