From fd333962065ffc99d7c3779da08a2066179694eb Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Fri, 26 Sep 2014 06:33:49 +0000 Subject: [PATCH] fm10k: Reduce buffer size when pages are larger than 4K This change reduces the buffer size to 2K for all page sizes. The basic idea is that since most frames only have a 1500 MTU supporting a buffer size larger than this is somewhat wasteful. As such I have reduced the size to 2K for all page sizes which will allow for more uses per page.
