    Subject[PATCH 5.15 43/98] net: asix: fix "cant send until first packet is send" issue
    Date
    From: Oleksij Rempel <o.rempel@pengutronix.de>

    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.
