From c5d67bd78c5dc540e3461c36fb3d389fbe0de4c3 Mon Sep 17 00:00:00 2001 From: Tom Herbert Date: Mon, 28 Nov 2011 16:32:52 +0000 Subject: [PATCH] net: Add netdev interfaces for recording sends/comp Add interfaces for drivers to call for recording number of packets and bytes at send time and transmit completion. Also, added a function to "reset" a queue. These will be used by Byte Queue Limits. Signed-off-by: Tom Herbert Acked-by: Eric Dumazet Signed-off-by: David S.
