Subject: [PATCH 5/9] brcm80211: fmac: postpone dongle RF enabling.
Date: Wed, 11 Apr 2012 11:52:47 +0200 [thread overview]
Message-ID: <1334137971-3972-6-git-send-email-arend@broadcom.com> (raw)
In-Reply-To: <1334137971-3972-1-git-send-email-arend@broadcom.com>
From: Franky Lin <frankyl@broadcom.com>
BRCMF_C_UP is the command that asks the firmware to enable RF of
dongle. Some firmware initialization steps must be performed during
RF is down. Postpone BRCMF_C_UP firing until brcmf_netdev_open get
called to ensure firmware have enough time to finish
initialization.
