Summary: behavior is different in Wily, sometimes not working, sometimes working but fails on heavy traffic.
Done some test check booting a Asus n551 on Ubuntu 15.10 live (wily werewolf). ## First test : one-way link only? First (sanity check / scientific control), tested integrated Ethernet port which works flawlessly. With tested device (same Ethernet cable, cat 5e) at first try behavior seems to have improved compared with previous Ubuntu releases: * ethernet auto-negociation is fast (like on previous kernels when it worked in USB2) * mii-tool is fast (typical 0.05s) (like on previous kernels when it worked in USB2) * few lines in dmesg (like on previous kernels when it worked in USB2) * but DHCP does not complete "tcpdump -n -i devicename" on both sides showed that packets sent by tested device are received on remote side but packets sent from remote side are not received by device (even ARP packets). Tried reversing cable just in case, behavior is the same. Just plugging the same cable to integrated Ethernet of same machine instead of tested device, everything works. Tested with another cable, same result. ## Subsequent tests: works then fails on heavy traffic * Plugged the device in another USB port. Everything seemed to worked. * Then tested again in the initial port. Worked again. Then after a moment (testing with dd anc nc), same problem (device received no packet). * Unplugging then plugging the device -> no longer creates ethernet device enx(encodedmacaddress) * Unplugging then plugging the device -> works again but load test using dd and nc quickly comes to the same problem. Conclusion: behavior is different in Wiley, sometimes not working, sometimes working. Problem seems different from previous ones. I attached part of dmesg. Promiscuous mode is when I used tcpdump. ** Attachment added: "dmesg_test_asix_short.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1269883/+attachment/4503341/+files/dmesg_test_asix_short.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1269883 Title: 0b95:1790 [Asus N55SF] Bad performance of Asix Ethernet-to-USB device on USB3 port Status in Linux: Unknown Status in linux package in Ubuntu: Confirmed Bug description: Plugging USB-to-ethernet device ID 0b95:1790 ASIX Electronics Corp. in USB3 port yields slow performance, dmesg flooded with errors. Plugging on USB2 port, exact same situation otherwise, works well. This is reproducible 3 out of 4 attempts. Machine has 2 USB3 ports on the left, 2 USB2 ports on the right. ### When working (USB2 port) * ethernet auto-negociation is fast * mii-tool is fast (typical 0.05s) * few lines in dmesg * good performance ### When failing : * ethernet auto-negociation fails, then sometimes eventually works * mii-tool is slow (10s of seconds instead of 0.05s) time sudo mii-tool eth0: no link eth1: 10 Mbit, half duplex, no link real 0m40.014s user 0m0.013s sys 0m0.006s time sudo mii-tool eth0: no link eth1: 10 Mbit, half duplex, no link real 0m50.015s user 0m0.011s sys 0m0.011s time sudo mii-tool eth0: no link eth1: negotiated 100baseTx-FD, link ok real 0m10.051s user 0m0.000s sys 0m0.012s But on some attempts mii-tool is fast... time sudo mii-tool eth0: no link eth1: negotiated 100baseTx-FD, link ok real 0m0.057s user 0m0.011s sys 0m0.012s * DHCP eventually completes (after about 30 seconds) then ethernet works. * whole system behaviour feels a little sluggish (not very clear, though) * mii-tool still slow (10s of seconds instead of 0.05s) ## dmesg when failing Full dmesg attached.
