From efafb28ff39f7989ee27e485721025e8ed86182c Mon Sep 17 00:00:00 2001 From: Oleksij Rempel Date: Fri, 24 Jun 2022 09:51:38 +0200 Subject: [PATCH] net: asix: fix "can't send until first packet is send" issue commit 805206e66fab4ba1e0ebd19402006d62cd1d4902 upstream. If cable is attached after probe sequence, the usbnet framework would not automatically start processing RX packets except at least one packet was transmitted. On systems with any kind of address auto configuration this issue was not detected, because some packets are send immediately after link state is changed to "running". With this patch we will notify usbnet about link status change provided by the PHYlib.
