net: dsa: mv88e6xxx: Request for stable inclusion

Hi,

I would like to request the commit below to be applied to the 6.1-stable tree:

91e87045a5ef ("net: dsa: mv88e6xxx: Add RGMII delay to 88E6320")

Without this commit, there is a failure to retrieve an IP address via DHCP.

Thanks,

Fabio Estevam
