Hi all,
I've experienced a similar problem but didn't get to analyzing it
deeper (or reporting) unfortunately ; the device is
ugen0.8: <ASIX Elec. Corp. AX88179> at usbus0, cfg=0 md=HOST spd=SUPER
(5.0Gbps) pwr=ON (124mA)
bLength = 0x0012
bDescriptorType = 0x0001
bcdUSB = 0x0300
bDeviceClass = 0x00ff <Vendor specific>
bDeviceSubClass = 0x00ff
bDeviceProtocol = 0x0000
bMaxPacketSize0 = 0x0009
idVendor = 0x0b95
idProduct = 0x1790
bcdDevice = 0x0100
iManufacturer = 0x0001 <ASIX Elec. Corp.>
iProduct = 0x0002 <AX88179>
iSerialNumber = 0x0003 <000000000000C>
bNumConfigurations = 0x0001
what I've noticed so far -
dhclient complains about wrong ip length -
% sudo dhclient ue1
DHCPDISCOVER on ue1 to 255.255.255.255 port 67 interval 7
ifconDHCPDISCOVER on ue1 to 255.255.255.255 port 67 interval 15
ip length 328 disagrees with bytes received 332.
accepting packet with data after udp payload.
DHCPOFFER from 192.168.10.1
DHCPREQUEST on ue1 to 255.255.255.255 port 67
ip length 328 disagrees with bytes received 332.
accepting packet with data after udp payload.
DHCPACK from 192.168.10.1
bound to 192.168.10.7 -- renewal in 3600 seconds.
Running iperf3 & watching netstat -i at the same time on the interface
in question shows increasing InErrors on the interface -
Name Mtu Network Address Ipkts Ierrs Idrop
Opkts Oerrs Coll
...
ue1 1500 <Link#4> 00:0e:c6:c6:db:ea 66333 354 0
35939 0 0
ue1 - 192.168.10.0/24 192.168.10.7 66323 - -
35927 - -
Iperf reports ~37.1 Mbits/sec on the interface.
If I attach the device on a USB2 port (or force USB2 speed on the
port) I was able to get ~ 150-200Mbits on the same system with the
same device.
This particular system has an Intel Lynx Point USB 3.0 controller
pciconf -lv | grep -A 4 xhci
xhci0 at pci0:0:20:0: class=0x0c0330 card=0x8179103c chip=0x8c318086
rev=0x05 hdr=0x00
vendor = 'Intel Corporation'
device = '8 Series/C220 Series Chipset Family USB xHCI'
class = serial bus
subclass = USB
,is running FreeBSD 12.0-CURRENT #19 r315483M (M stands for a patch
similar to https://people.freebsd.org/~syrinx/freebsd_xhci-20170318-01.diff
needed to trick the controller on that particular system to actually
use USB3.0 speeds).
The same ASIX AX88179 device worked just fine reaching over 500
Mbits/sec on another system running 11.0-RELEASE-p7 with a different
USB 3 controller (will double check and report back at first
opportunity).
Hope this helps.
cheers,
Shteryana
