Subject: [PATCH net-next 1/1] stmmac: intel: change all EHL/TGL to auto detect phy addr

From: Voon Weifeng <[email protected]>

Set all EHL/TGL phy_addr to -1 so that the driver will automatically
detect it at run-time by probing all the possible 32 addresses.

This fixes PHY detection on one of our EHL-based boards. Can this also
be applied to stable 5.10?

Sure.

Greg, we'd like to request a backport of the following commit to 5.10.

It's relatively small, and Jan reports it makes his boards detect the
PHY. The change went in via -next and into Linus's tree during the 5.11
merge window.
