From b635e06993076c3c8f8cc766b183be7da3baafdb Mon Sep 17 00:00:00 2001 From: David Daney Date: Wed, 5 May 2010 13:03:11 +0000 Subject: [PATCH] netdev: octeon_mgmt: Free TX skbufs in a timely manner. We also reduce the high water mark to 1 so skbufs are not stranded for long periods of time. Since we are cleaning after each packet, no need to do it in the transmit path.
