From 3e8d69352bd9ac7287ab735d45582d79c1f9f2d9 Mon Sep 17 00:00:00 2001 From: Eyal Shapira Date: Thu, 7 Jun 2012 23:39:21 +0300 Subject: [PATCH] wlcore: add debugfs control over rx interrupt pacing Add control over several conf fields which combined control the rx interrupt pacing mechanism, that is avoiding getting an interrupt following a single frame rx but instead have the FW trigger the interrupt only after a certain amount of frames received or a timeout.
