# \[PATCH net-next\] net: dsa: rtl8365mb: add GMII as user port mode - From: luizluca@gmail.com - Date: 2021-12-14 19:07:16 - List: netdev - Page: https://ratatoskr.run/netdev/2021/12/11218858 - Thread: https://ratatoskr.run/netdev/2021/12/11218858/t.md ```text From: Luiz Angelo Daros de Luca 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.
