From 16051b0e245219563ac8d145f29217ac7a6ce5ec Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Mon, 10 Sep 2012 18:30:44 -0700 Subject: [PATCH] mwifiex: update adapter->bss_prio_tbl[j].bss_prio_cur correctly "adapter->bss_prio_tbl[j].bss_prio_head" points to linked list of interfaces with priority 'j'. "bss_prio_tbl[j].bss_prio_cur" is supposed to point to next interface every time the routine for dequeuing the packet is called. This ensures that each interface gets fair chance. Currently we have AP and station interfaces with priority '0'. Therefore "adapter->bss_prio_tbl[0].bss_prio_cur" should alternately point to AP and station nodes. Since "bss_prio_cur" is not correctly updated, for each packet picked for AP, two packets are picked for station interface. This patch fixes the problem by correctly updating "bss_prio_cur".
