From 6a5311982e423ddacc2e39e1e32f4371756752d6 Mon Sep 17 00:00:00 2001 From: Yuval Mintz Date: Thu, 19 Nov 2015 17:04:35 +0200 Subject: [PATCH] bnx2x: Add new SW stat 'tx_exhaustion_events' Driver already has an internal counter for number of times a given queue had to be stopped due to Tx ring exhaustion. This add the counter to the statistics presented by driver, e.g., by using `ethtool -S'. Signed-off-by: Yuval Mintz Signed-off-by: David S.
