In comparison, for the 6.6 vendor kernel in OrangePiOS:
- Client tests give similar results both on eth0 and eth1
- Server tests are very similar on eth0, but lose
  between 50-60 Mbits/sec on eth1:
  [ 5] 0.00-10.00 sec 1.04 GBytes 889 Mbits/sec 56 sender
  [ 5] 0.00-10.01 sec 1.03 GBytes 882 Mbits/sec receiver
  (as seen from the PC client)

Changes in V2:
- Remove the commit configuring k1_emac driver as a built-in by default,
  as suggested by Emil Renner Berthing
- Improve the message for the commit adding Ethernet and PDMA,
  as suggested by Yixun Lan
- Add DT aliases for eth0 and eth1
  as suggested by Vivian Wang
- Add iperf3 test results to this cover letter
  as suggested by Vivian Wang
