From 17e8cec87586c26b953c6541c8a045e906ea046c Mon Sep 17 00:00:00 2001 From: Marc Yang Date: Mon, 16 May 2011 19:17:52 -0700 Subject: [PATCH] mwifiex: CPU mips optimization with NO_PKT_PRIO_TID If we go through the entire for loop in mwifiex_wmm_get_highest_priolist_ptr() and don't find any packets, set highest_queued_prio to NO_PKT_PRIO_TID (< LOW_PRIO_TID).
