On windows 10, I see the network icon toggling up and down.

From debian:stable

sudo tail -f /var/log/kern.log
Feb 24 07:02:40 DESKTOP-KO7G4JT kernel: [ 2748.506826] ixgbe 0000:07:00.0 enp7s0: NIC Link is Down
Feb 24 07:02:40 DESKTOP-KO7G4JT kernel: [ 2748.610780] ixgbe 0000:07:00.0 enp7s0: NIC Link is Up 10 Gbps, Flow Control: RX/TX

Why my windows and debian machine toggle deconnection state and have very poor performance speed on samba transfer ?

Does some body have any tips to help me debug my situation?
