Date: Fri, 26 Feb 2010 03:54:20 -0800 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: netdev@...r.kernel.org, gospo@...hat.com, Peter P Waskiewicz Jr <peter.p.waskiewicz.jr@...el.com>, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [net-next-2.6 PATCH] ethtool: Add n-tuple string length to drvinfo and return it From: Peter Waskiewicz <peter.p.waskiewicz.jr@...el.com> The drvinfo struct should include the number of strings that get_rx_ntuple will return. It will be variable if an underlying driver implements its own get_rx_ntuple routine, so userspace needs to know how much data is coming.
