After 2 weeks, I have to say, that this kext is not stable on my Mojave system. If I send too much data at full speed to a linux server, the network adapter will freeze and the kernel_task process will go wild taking a high amount of processing power.
I tested it via samba and iperf3:
./iperf3 --client 192.168.0.1
Connecting to host 192.168.0.1, port 5201
[ 4] local 192.168.0.10 port 49464 connected to 192.168.0.1 port 5201

...
On the other hand, receiving gigabytes of data at full speed is not a problem, only sending data is a problem:
./iperf3 -s

I tried to lower the adapters MTU size, but it did not help.
If the adapter freezes, I have to reboot my system or reload the kext like so:
sudo kextunload /Library/Extensions/AtherosL1cEthernetSierra.kext; sudo kextload /Library/Extensions/AtherosL1cEthernetSierra.kext
What could be the problem? Does anyone have an idea?
