From: Matt Carlson Date: Mon, 21 Nov 2011 15:01:18 +0000 (+0000) Subject: tg3: Adjust BD replenish thresholds X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=513aa6ea39adfc9daf5b4bc33b49008733c3eb51;p=linux-beck.git tg3: Adjust BD replenish thresholds The BD replenish thresholds for the 57765 and newer ASIC revs are a little strict. They were tuned for a mode that is currently unused. This patch relaxes the thresholds so that they are set to values more inline with the resources available.
