Subject: [PATCH] net: ethernet: mediatek: Allow gaps in MAC allocation
|
|
|
|
Some devices with MediaTek SoCs don't use the first but only the second
|
|
MAC in the chip. Especially with MT7981 which got a built-in 1GE PHY
|
|
connected to the second MAC this is quite common.
|
|
Make sure to reset and enable PSE also in those cases by skipping gaps
|
|
using 'continue' instead of aborting the loop using 'break'.
|
|
|
|
Fixes: dee4dd10c79a ("net: ethernet: mtk_eth_soc: ppe: add support for multiple PPEs")
