Hi,

This series depends on a previous series currently sitting in net.git
starting with
	commit 562c5a70400c ("net: mediatek: only wake the queue if it is stopped")
up to
	commit 82c6544dddc6 ("net: mediatek: remove superfluous queue wake up
call")

i just double checked and with the series applied this compile error is gone

	John
