From ab79be3eebf28be5315e43d0002ebcc05858af0b Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Wed, 29 Oct 2014 21:34:30 +0100 Subject: [PATCH] mac802154: add IEEE802154_HW_ARET hw flag This patch adds a new IEEE802154_HW_ARET hardware flag for indicating that the transceiver supports ARET handling. Also remove the IEEE802154_HW_FRAME_RETRIES from IEEE802154_HW_CSMA flag. Frame retries handling is part of ARET.
