I found more information on the problem using command
@ubuntu:~$ sudo lshw

In the settings shows that autonegotiation=off.
When I try to enable autonegotiation
@ubuntu:~$ sudo ethtool -s p2p1 autoneg on
we have the answer:
Cannot set new settings: Invalid argument
not setting autoneg
And dmesg gives a message
[2939524.031187] i40e 0000:0a:00.0 p2p1: Autoneg not supported on this phy
Is it possible to enable auto-negotiation? and why is he not supported the PHY?
