    > have tested this series, basicly it works, but i get only ~620 Mbits/sec (much more i will need on wan) in tx-mode of r2, rx-mode (iperf3 -c IP -R on r2) gets full 939 Mbits/sec. Both no retransmitts.

    tested the vlan_aware way with 5.15.80 and got better result

    ip link add br0 type bridge vlan_filtering 1
    ip l set aux master br0
    ip l set wan master br0
    bridge vlan add vid 99 dev wan
    bridge vlan add vid 99 dev aux
    bridge vlan
    ip l s eth1 up
    ip l s wan up
    ip a a 192.168.0.11/24 dev eth1
    ip l s br0 up
    ip l s aux up

    i see traffic on eth1 increasing and iperf3 shows in both directions ~940Mbit/s, no strange mesages in dmesg while testing...where do you see these?

    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.

    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? Do you test with bpi-r2 or only any other board and change r2 to have same DT?

    regards Frank
