6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Florian Fainelli <florian.fainelli@xxxxxxxxxxxx>
[ Upstream commit 46ded709232344b5750a852747a8881763c721ab ]
Some Wake-on-LAN modes such as WAKE_FILTER may only be supported by the MAC,
while others might be only supported by the PHY. Make sure that the .get_wol()
returns the union of both rather than only that of the PHY if the PHY supports
Wake-on-LAN.
When disabling Wake-on-LAN, make sure that this is done at both the PHY
and MAC level, rather than doing an early return from the PHY driver.
Fixes: 7e400ff35cbe ("net: bcmgenet: Add support for PHY-based Wake-on-LAN")
Fixes: 9ee09edc05f2 ("net: bcmgenet: Properly overlay PHY and MAC Wake-on-LAN capabilities")
