From 0e490657c7214cce33fbca3d88227298c5c968ae Mon Sep 17 00:00:00 2001 From: Aditya Shankar Date: Fri, 7 Apr 2017 17:24:58 +0530 Subject: [PATCH] staging: wilc1000: Fix problem with wrong vif index The vif->idx value is always 0 for two interfaces. wl->vif_num = 0; loop { ... vif->idx = wl->vif_num; ... wl->vif_num = i; .... i++; ... } At present, vif->idx is assigned the value of wl->vif_num at the beginning of this block and device is initialized based on this index value. In the next iteration, wl->vif_num is still 0 as it is only updated later but gets assigned to vif->idx in the beginning. This causes problems later when we try to reference a particular interface and also while configuring the firmware. This patch moves the assignment to vif->idx from the beginning of the block to after wl->vif_num is updated with latest value of i.
