tested the vlan_aware way with 5=2E15=2E80 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=2E168=2E0=2E11/24 dev eth1
ip l s br0 up
ip l s aux up

i see traffic on eth1 increasing and iperf3 shows in both directions ~940M=
bit/s, no strange mesages in dmesg while testing=2E=2E=2Ewhere do you see t=
hese?

tested vlan-way with 6=2E2 and felix' Patches to more comparable with your=
 test=2E=2E=2Eand got same result (~625Mbit/s in tx and 940Mbit/s in rx-mod=
e=3D-R on r2)=2E=2E=2Eso it seems anything between 5=2E15 and 6=2E2 reduced=
 gmac1 tx bandwidth=2E

to summarize:

i get same result with your patches and my old vlan_bridge way with same c=
odebase=2E=2E=2Ehow 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?
