Subject: [PATCH] net: ethernet: mtk_eth_soc: avoid port_mg assignment on
|
|
MT7622 and newer
|
|
|
|
On newer chips, this field is unused and contains some bits related to queue
|
|
assignment. Initialize it to 0 in those cases.
|
|
Fix offload_version on MT7621 and MT7623, which still need the previous value.
