Date: Mon, 6 Dec 2010 10:28:49 -0800 From: "Matt Carlson" <mcarlson@...adcom.com> To: davem@...emloft.net cc: netdev@...r.kernel.org, andy@...yhouse.net, mcarlson@...adcom.com Subject: [PATCH net-next 1/6] tg3: Raise the jumbo frame BD flag threshold The current transmit routines set the jumbo frame BD flag too aggressively. This can reduce performance for common cases. This patch raises the jumbo flag threshold to 1518, up from 1500.
