Subject: [PATCH 3/3] net: bgmac: use PHY subsystem for initializing PHY
|

This adds support for using bgmac with PHYs supported by standalone PHY
|
||
|
|
drivers. Having any PHY initialization in bgmac is hacky and shouldn't
|
||
|
|
be extended but rather removed if anyone has hardware to test it.
