Hi Andrew,

     Use default mdio configure, After module compilation, mdio alias configure
is following and it doesn't match

     the match phy dev(mdio dev)  uevent, because the mdio alias configure
"0000000101000001000011111001????"  include "?" and

A PHY ID generally break up into 3 parts.

The OUI of the manufacture.
The device.
The revision

The ? means these bits don't matter. Those correspond to the
revision. Generally, a driver can driver any revision of the PHY,
which is why those bits don't matter.

So when a driver probes with the id 00000001010000010000111110010110
we expect user space to find the best match, performing wildcard
expansion. So the ? will match anything.

Since this is worked for a long time, do you have an example where it
is broken? If so, which PHY driver? If it is broken, no driver is
loaded, or the wrong driver is loaded, i expect it is a bug in a
specific driver. And we should fix that bug in the specific driver.

Hi Andrew,

The string like "0000000101000001000011111001????" dont't match any mdio driver, and i said it include "? that "?" doesn't match any driver, in addition that include Binary digit
like "0000000101000001000011111001", that binary digit doesn't match any driver, that should use Hexadecimal for phy id, and I test on some platform, not only a platform, it isn't some
specifi driver issue, it is gerneral issue. please you note.  that phy driver match phy device must use whole string "MODALIAS=xxxyyzz", not partial match.

Please give a concrete example. Show us udev logs of it not working,
it failing to find a match.
