Subject: [PATCH 5/5] ath9k_hw: add an extra delay when reseting AR_RTC_RESET
Date: Mon, 21 Jun 2010 18:38:51 -0400 [thread overview]
Message-ID: <1277159931-7797-6-git-send-email-lrodriguez@atheros.com> (raw)
In-Reply-To: <1277159931-7797-1-git-send-email-lrodriguez@atheros.com>
Without this we could start trying to work with the device without
it being fully functional yet and loose some packets upon resume.
