From 98323895c021ff010685ba77773af876eff503a5 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Wed, 28 Nov 2012 11:42:41 +0200 Subject: [PATCH] wl18xx: limit Tx for the AP single-STA-in-PSM case Treat a single connected STA in PSM as a slow link and regulate Tx speed according to slow link priority/stop thresholds. This allows us to avoid flooding the FW, while delivering decent throughput to a peer in forced-PSM.
