Backport of the latest upstream Realtek PHY patches. WoL uses devm_pm_set_wake_irq(), so the patch that adds this function has also been backported.

Subject: [PATCH] net: phy: realtek: disable MDIO broadcast
|
|
|
|
RealTek's PHYs by default also listen on MDIO address 0 which is defined
|
|
as broadcast address. This can lead to problems if there is an actual PHY
|
|
(such as MT7981 built-in PHY) present at this address, as accessing that
|
|
PHY may then confuse the RealTek PHY.
|
|
|
|
Disabled listening on the MDIO broadcast address to avoid such problems.
