If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit fbeaed384acc580a09bb68de923c0dcadf96380e Author: Aaro Koskinen <aaro.koskinen@xxxxxx> Date: Fri Sep 24 01:00:16 2021 +0300 smsc95xx: fix stalled rx after link change [ Upstream commit 5ab8a447bcfee1ded709e7ff5dc7608ca9f66ae2 ] After commit 05b35e7eb9a1 ("smsc95xx: add phylib support"), link changes are no longer propagated to usbnet. As a result, rx URB allocation won't happen until there is a packet sent out first (this might never happen, e.g. running just ssh server with a static IP). Fix by triggering usbnet EVENT_LINK_CHANGE. Fixes: 05b35e7eb9a1 ("smsc95xx: add phylib support") Signed-off-by: Aaro Koskinen <aaro.koskinen@xxxxxx> Signed-off-by: David S.
