From 1486774d69f6e58da16cdae8f17c77ec6569f711 Mon Sep 17 00:00:00 2001 From: "stefan@datenfreihafen.org" Date: Tue, 26 Mar 2013 12:41:30 +0000 Subject: [PATCH] ieee802154/at86rf230: Implement hardware address filter callback. Implement the filter function to update short address, pan id and ieee address on change. Allowing for hardware address filtering needed for auto ACK.
