    Subject[PATCH AUTOSEL 4.14 35/61] ax88179_178a: Check for supported Wake-on-LAN modes
    Date
    From: Florian Fainelli <f.fainelli@gmail.com>

    [ Upstream commit 5ba6b4aa9a410c5e2c6417df52b5e2118ea9b467 ]

    The driver currently silently accepts unsupported Wake-on-LAN modes
    (other than WAKE_PHY or WAKE_MAGIC) without reporting that to the user,
    which is confusing.

    Fixes: e2ca90c276e1 ("ax88179_178a: ASIX AX88179_178A USB 3.0/2.0 to gigabit ethernet adapter driver")
