hello,drivers-networking engineer£º

    My Development Environment 
      Host: Ubuntu 14.
      Qnx: SDP 7.0
     Target: iMx6q Sabre Auto/AI
    
I face a strange problem when i am debugging  phy(atheros ar8095) driver on imx6q board,  when i have started the io-pkt service and configed ip, the nicinfo changes below:
  --> nicinfo
    fec0: 
  i.MX6 Ethernet Controller

  Link is DOWN

  Physical Node ID ........................... 000012 345678
  Current Physical Node ID ................... 000012 345678
  Current Operation Rate ..................... Unknown
  Active Interface Type ...................... MII
    Active PHY address ....................... 0
  Maximum Transmittable data Unit ............ 1500
  Maximum Receivable data Unit ............... 1500
  Hardware Interrupt ......................... 0x96
  Hardware Interrupt ......................... 0x97
  Memory Aperture ............................ 0x2188000 - 0x2188fff
  Memory Aperture ............................ 0x2098000 - 0x2098fff
  Promiscuous Mode ........................... Off
  Multicast Support .......................... Enabled
  
and the network port status is :
  -->ifconfig
fec0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	address: 00:00:12:34:56:78
	media: Ethernet 10baseT full-duplex (none)
	status: no carrier
	inet 192.168.1.11 netmask 0xffffff00 broadcast 192.168.1.255
	inet6 fe80::200:12ff:fe34:5678%fec0 prefixlen 64 scopeid 0x11

whatever the configuration of the phy has made,the  fec0's status is always no carrier. by the way, cable is connected to my win10 computer.

do you have any suggestions to my problem? thank u!
