From df8944cf5cd3794c46e95e0404038376ee7f8dda Mon Sep 17 00:00:00 2001 From: Matt Carlson Date: Wed, 27 Jul 2011 14:20:46 +0000 Subject: [PATCH] tg3: Reintroduce tg3_tx_ring_info The following patches will require the use of an additional flag in the ring_info structure. The use of this flag is tx path specific, so this patch defines a specialized ring_info structure. Signed-off-by: Matt Carlson Reviewed-by: Michael Chan Signed-off-by: David S.
