Hi all,
On Odroid XU3/4 board, since 5.6 with 1019fe2c728003f89ee11482cf8ec81dbd8f15ba,
the network is not working properly.
After properly booting, when trying to connect to the board via ssh, the board
hang for a while and this message happen:

After that, the board continue working from serial console only, but the board
doesn't pong anymore.
Reverting some change fix the issue.
