Subject: [PATCH v2] cs89x0 : packet reception not working
Date: Mon, 27 Aug 2012 23:53:51 +0200 [thread overview]
Message-ID: <1346104431-3784-1-git-send-email-jaccon.bastiaansen@gmail.com> (raw)
The RxCFG register of the CS89x0 could be configured incorrectly
(because of misplaced parentheses), resulting in the disabling
of packet reception.
