Hi Andrew,
You have advised me to change the compatibility to "marvell,mv88e6190".
The problem is that my linux version is Xilinx 4.4.0 (2016.2) - it contains
mv88e6xxx driver files that do not support 6190 (though they do support 6085)
and the driver has slightly different file tree.

On unsuccesful ip6_datagram_connect(), if the failure is caused by
ip6_datagram_dst_update(), the sk peer information are cleared, but
the sk->sk_state is preserved.
If the socket was already in an established status, the overall sk
status is inconsistent and fouls later checks in datagram code.
The syzbot reported an l2tp oops that uncovered some races in the l2tp xmit
path and a partially related issue in the generic ipv6 code.
We need to address them separately.
v1 -> v2:
- add missing fixes tag in patch 1
- fix several issues in patch 2
Paolo Abeni (2):
net: ipv6: keep sk status
When creating a new socket, l2tp_tunnel_create() ensures that
such socket is connected, but when using a socket provided by
the user space, no check is done on the socket state.
This may foul the later check for ipv6 sockets that are
ipv4-mapped, e.g. in case of unconnected ipv6 socket bound to
