This is my first post to this website. I this that my question is related to serverfault cause it is related to ethernet communication issue. If you disagree please let me know what is the appropriate place to move this post to. Thanks.I am using USB3 to GigE converter - since I don't have GigE on my linux board. My problem is after connecting to an IP camera. It works for sometime and I am able to receive images but then it stops after one or two minutes. After it stops I cannot ping anything and I can see there are error in rx packets.Here is my ifconfig before connecting to the camera:ifconfigeth1      Link encap:Ethernet  HWaddr 00:13:3b:99:28:56            inet addr:192.168.0.117  Bcast:192.168.0.255  Mask:255.255.255.0          inet6 addr: fe80::213:3bff:fe99:2856/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:4000  Metric:1          RX packets:102 errors:0 dropped:0 overruns:0 frame:0          TX packets:39 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000          RX bytes:29172 (29.1 KB)  TX bytes:6614 (6.6 KB)and here is the same after connecting to the camera and stops responding:ifconfigeth1      Link encap:Ethernet  HWaddr 00:13:3b:99:28:56            inet addr:192.168.0.117  Bcast:192.168.0.255  Mask:255.255.255.0          inet6 addr: fe80::213:3bff:fe99:2856/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:4000  Metric:1          RX packets:137338 errors:1604 dropped:0 overruns:0 frame:0          TX packets:3662 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:274563593 (274.5 MB)  TX bytes:287885 (287.8 KB)Clearly there are error in RX packets, I am not sure why.Here is the ethtool eth1 output:ethtool eth1Settings for eth1:    Supported ports: [ TP MII ]    Supported link modes:   10baseT/Half 10baseT/Full                             100baseT/Half 100baseT/Full                             1000baseT/Half 1000baseT/Full     Supported pause frame use: No    Supports auto-negotiation: Yes    Advertised link modes:  Not reported    Advertised pause frame use: No    Advertised auto-negotiation: No    Speed: 1000Mb/s    Duplex: Full    Port: MII    PHYAD: 3    Transceiver: internal    Auto-negotiation: offCannot get wake-on-lan settings: Operation not permitted    Current message level: 0x00000007 (7)                   drv probe link    Link detected: yes
