Has anyone reviewed the various available usb3 gigabit adapters for
features, linux driver support, bufferbloat, BQL(can usb NICs do BQL?), etc?
With some single board computers having reasonable usb3 now, I can see
people making routers out of them. But it would also be good to know if
that's reasonable and in general which to recommend.
Some searching in drivers/net/usb/ for gigabit capable things I found:
aqc111: Aquantia AQtion USB to 5GbE
ax88179_178a: ASIX AX88179, ASIX AX88178A, Sitcomm LN-032
lan78xx: 7800/7801 usb3 devices
r8152: r8153 usb3 devices
smsc75xx: only usb2?
Maybe there are others?
In real life I have:
1) an r8152 device (came with a Asus laptop). It's been reliable.
2) an ax88179_178a device
(https://www.amazon.com/gp/product/B00MYTSN18). Worked at first, but
started acting up after a recent kernel upgrade and I haven't tracked
down what changed yet.
I've attached some ethtool output for the features of each.
Ebay has tons of $10 options, but little details. Some also have
integrated USB ports on them, some are "docking station" like and have
hdmi as well. If you search for "usb 3.2" you can find some that are
2.5gbit.
Also some interesting (but from 2019) info in this post

Hi Matt.
Over on the OpenWrt forum there are a lot of reports of tp-link's ue300 using an RTL8153 chip working robustly and reliably with speeds up to the expected limit for gigabit ethernet. Reports for Asix model(s) indicate some driver inefficiencies that make it impossible ot reach the expected 940-950 Mbps TCP/IPv4 goodput.
As far as I can tell none of the USB ethernet dongles support BQL... (this is why the OpenWrt on raspberry pi 4B crowd generally uses the USB dongle as the WAN interface and uses a traffic shaper there to keep latency under load in check, while the on-board ethernet adapter is used without saer as the LAN interface, typically connected to a switch).
Regards
Sebastian
