From 1829c13c8afb05306889b03ba9582ccb5071d29b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C5=81ukasz=20Duda?= Date: Sun, 15 Jun 2025 22:26:20 +0200 Subject: [PATCH] net: openthread: Make Radio workqueue priority configurable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit makes the Radio workqueue priority configurable by the application. Additionally, the default priority has been adjusted to allow transmit operations to occur before the entire RX queue is processed.
