From 787b2dc44aa1ae2524f022659c6c6b2d3c979e04 Mon Sep 17 00:00:00 2001 From: Ido Yariv Date: Fri, 24 Jun 2011 13:03:36 +0300 Subject: [PATCH] wl12xx: Increase low & high TX watermarks The current TX watermark settings cause the driver to stop queues too frequently. Among other things, this can have a negative impact on WMM prioritization, since mac80211 sorts pending packets by their ACs. Fix this by increasing the high watermark to 256 packets. Increase the low watermark to 32 to minimize periods with queues being stopped.
