Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Help getting StarTech 10gbe card working in Ubuntu 18
Then I found this site: https://github.com/acooks/tn40xx-driver that has an updated driver supporting kernel 5.x, and with that one I was able to get the 'make' / 'make install' driver commands to at least work supposedly. Now the 'lshw' status seems normal... except it says "port=AUI" instead of "port=twisted pair" like the other onboard ethernet ports. And it still doesn't work, when I plug in a cable nothing happens, no link detected.

Petalinux <---> FPGA using DMA
I started off by using udmabuf to map regions of my memory to the userspace ensuring that there are no conflicts with the kernel and app.

Petalinux and DMA with Xilinx SoC
Install the u-dma-buf kernel module to map a section of your virtual address space to be contiguous in your physical address space.

[BEGINNER] How to send Ethernet packets from HPS to FPGA on Cyclone V ? (DMA)
Lastly, what I think would be the way - DMA so that the CPU doesn't really have to copy each and every packet into RAM - but I have no idea how to go about this, but I've seen some syscalls that shall be able to tell Linux to actually 'put' packets there (I really am a beginner, sorry guys, I'm trying my best tho!). And I've had a slight experience with u-dma-buf kernel module (https://github.com/ikwzm/udmabuf), which might be the place we wanna Linux to put packets to. Then, we'd give the FPGA the address of the buffer allocated by u-dma-buf and it would simply start the processing from there. Is that correct or am I missing something ?
