[PATCH net-next v2 2/9] net: ethernet: ti: am65-cpsw: move free desc queue mode selection in pdata

From: Grygorii Strashko
Date: Thu Oct 15 2020 - 19:19:46 EST


In preparation of adding more multi-port K3 CPSW versions move free
descriptor queue mode selection in am65_cpsw_pdata, so it can be selected
basing on DT compatibility property.
