I suggest you read my mails with higher > attention so both of our time is spent efficiently. sorry if i misseed this detail, but it was not part of the instructions i got from mtk and did not found it in our mail-conversion. why do i need to add the gmac into the bridge?? the gmac is connected physically to mt7531 p5, and my vlan_aware bridge bridges this port (aux=p5) with wan, so i see no need to add eth1 to this bridge too...traffic on wan is tagged with vlan 99 and leaving untagged on aux which is arriving eth1... > > tested vlan-way with 6.2 and felix' Patches to more comparable with your test...and got same result (~625Mbit/s in tx and 940Mbit/s in rx-mode=-R on r2)...so it seems anything between 5.15 and 6.2 reduced gmac1 tx bandwidth. > > I don't see an incentive to investigate unless the issue is confirmed on > a daily netdev/net-next.git main tree. have same result on net-next/main with your series, no additional patches on top except adding my build-script and defconfig. > > > > to summarize: > > > > i get same result with your patches and my old vlan_bridge way with same codebase...how do i see your problem with the vlan-bridge-way?
