This is a note to let you know that I've just added the patch titled net: dsa: qca8k: reduce mgmt ethernet timeout to the 5.18-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: net-dsa-qca8k-reduce-mgmt-ethernet-timeout.patch and it can be found in the queue-5.18 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit b41e060fb0824fb0d86d6abb42bf2f40db894fc9 Author: Christian Marangi <ansuelsmth@xxxxxxxxx> Date: Tue Jun 21 17:16:33 2022 +0200 net: dsa: qca8k: reduce mgmt ethernet timeout [ Upstream commit 85467f7da18992311deafdbf32a8d163cb1e98d7 ] The current mgmt ethernet timeout is set to 100ms. This value is too big and would slow down any mdio command in case the mgmt ethernet packet have some problems on the receiving part. Reduce it to just 5ms to handle case when some operation are done on the master port that would cause the mgmt ethernet to not work temporarily.
