From be86cbea1e9c3a4dd8faedcfa327495d09fe3531 Mon Sep 17 00:00:00 2001 From: Juuso Oikarinen Date: Thu, 27 May 2010 12:53:01 +0300 Subject: [PATCH] wl1271: Implement CMD_SET_STA_STATE to indicate connection completion to FW Implement the command function to send CMD_SET_STA_STATE to the firmware. This is used to indicate that association (and the related EAP negotiation) are complete. This is used to tune WLAN-BT coexistense priority towards BT, improving BT A2DP and SCO performance.
