Subject: [PATCH] net: phy: realtek: detect early version of RTL8221B
|
|
|
|
Early versions (?) of the RTL8221B PHY cannot be identified in a regular
|
|
Clause-45 bus scan as the PHY doesn't report the implemented MMDs
|
|
correctly but returns 0 instead.
|
|
Implement custom identify function using the PKGID instead of iterating
|
|
over the implemented MMDs.
