Hi NXP,

I am using a custom imx6dl board with android_p9.0.0_2.2.0-ga. From the command line, I did ifconfig eth0 up 192.168.30.240 and I did ip link and I can see the link is up.

130|sabresd_6dq:/ # ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: ip_vti0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ipip 0.0.0.0 brd 0.0.0.0
3: ip6_vti0@NONE: <NOARP> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/tunnel6 :: brd ::
4: sit0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/sit 0.0.0.0 brd 0.0.0.0
5: ip6tnl0@NONE: <NOARP> mtu 1452 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/tunnel6 :: brd ::
6: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
link/ether 00:de:fa:87:6e:d7 brd ff:ff:ff:ff:ff:ff

However when I did ifconfig eth0, I see all received packet is dropped.

sabresd_6dq:/ # ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:de:fa:87:6e:d7 Driver smsc95xx

Please advise. 

Thank You in advance.

what PHY do you use? the same as nxp board? or porting your own PHY? and could you reproduce this on nxp board?
