[PATCH net-next] net: dsa: rtl8365mb: add GMII as user port mode
From: luizluca@gmail.com
Date: 2021-12-14 19:07:16
From: Luiz Angelo Daros de Luca <luizluca@gmail.com> Recent net-next fails to initialize ports with: realtek-smi switch: phy mode gmii is unsupported on port 0 realtek-smi switch lan5 (uninitialized): validation of gmii with support 0000000,00000000,000062ef and advertisement 0000000,00000000,000062ef failed: -22 realtek-smi switch lan5 (uninitialized): failed to connect to PHY: -EINVAL realtek-smi switch lan5 (uninitialized): error -22 setting up PHY for tree 1, switch 0, port 0 Current net branch(3dd7d40b43663f58d11ee7a3d3798813b26a48f1) is not affected. I also noticed the same issue before with older versions but using a MDIO interface driver, not realtek-smi.
