From 5d82288b93db3bc7e943464f89079f1360ac3c50 Mon Sep 17 00:00:00 2001 From: Stefan Schmidt Date: Mon, 5 Dec 2016 14:47:20 +0100 Subject: [PATCH] ieee802154: atusb: implement .set_frame_retries ops callback From firmware version 0.3 onwards we use the TX_ARET mode allowing for automatic frame retransmissions. To actually make use of this feature we need to implement the callback for setting the frame retries. If the firmware version is to old print a warning and return with invalid value.
