Message-Id: <1233261028-27584-1-git-send-email-dhananjay@netxen.com> Date: Thu, 29 Jan 2009 12:30:28 -0800 From: Dhananjay Phadke <dhananjay@...xen.com> To: netdev@...r.kernel.org Cc: davem@...emloft.net Subject: [PATCH] netxen: revert jumbo ringsize Reducing jumbo ring size below 1024 reduces throughput for old firmwares (3.4.216 and older) running on older (NX2031) chip, so restore it back to 1024. This was reduced in commit 32ec803348b4d5f1353e1d7feae30880b8b3e342. Raising jumbo ring size from 512 to 1024, adds ~4MB per port, but there's still big saving because of original patch (~20MB per port).
