Dear Aleksandr,

> Please update commit message with exact commands for reproduction if possible.
that is sure to be done in v2, for now try

for the side acting as iperf3 server:
```
#!/bin/bash
# tunnel creation
# IPv4 addr         192.168.42.11/24
# IPv6 addr         2011::11/64
# IPv4oIP6GRE addr  192.168.44.11/24
# IPv6oIP6GRE addr  2023::11/64

ip l a gre1 type ip6gre remote 2011::12 local 2011::11 dev enp65s0f0np0
ip l s ip6tnl0 up
ip l s ip6gre0 up
ip l s gre1 up


# gre tunnel addresses
ip a a 2001:db8:1::1/64 dev gre1
ip a a 2023::11/64 dev gre1
ip a a 192.168.44.11/24 dev gre1

# device addresses
ip a a 2011::11/64 dev enp65s0f0np0
ip a a 192.168.42.11/24 dev enp65s0f0np0

iperf3 -s
```

for the side acting as iperf3 client:
```
#!/bin/bash
# tunnel creation
# IPv4 addr         192.168.42.12/24
# IPv6 addr         2011::12/64
# IPv4oIP6GRE addr  192.168.44.12/24
# IPv6oIP6GRE addr  2023::12/64

ip l a gre1 type ip6gre remote 2011::11 local 2011::12 dev enp65s0f0np0
ip l s ip6tnl0 up
ip l s ip6gre0 up
ip l s gre1 up

# gre tunnel addresses
ip a a 2001:db8:1::2/64 dev gre1
ip a a 2023::12/64 dev gre1
ip a a 192.168.44.12/24 dev gre1

# device addresses
ip a a 2011::12/64 dev enp65s0f0np0
ip a a 192.168.42.12/24 dev enp65s0f0np0

# tests with single stream
# test gre throughput
iperf3 -c 192.168.44.11 -t 20 -P 1
iperf3 -c 2023::11 -t 20 -P 1
# test normal throughput
iperf3 -c 192.168.42.11 -t 20 -P 1
iperf3 -c 2011::11 -t 20 -P 1
```
I hope this is expected answer.

Best regards,
