Subject: RE: [PATCH v2 2/2] net: ethernet: Add driver for Sunplus SP7021
Date: Mon, 29 Nov 2021 11:16:27 +0000	[thread overview]
Message-ID: <2c1d6de8d7284a92ae0317dcfc444d79@sphcmbx02.sunplus.com.tw> (raw)

Hi Andrew,


Thanks a lot for explanation!.

I will modify code to set hardware external PHY address to 31.
In mii_read() or mii_write() functions, set hardware external PHY 
address to real PHY address, so that mii read or write command can 
be sent out by hardware. Set hardware external PHY address back to 
31 after mii read or write command done.


Best regards,
Wells Lu
