Yes, in the meantime we have made some performance improvements. Currently the throughput numbers are approx.: TX: 30Mbit/s RX: 20Mbit/s I have seen RX and TX throughputs of up to 50Mbit/s on my RTL8822CS, but I cannot reliably reproduce this (meaning: if I don't touch my board and run the same iperf3 test again then in one run it may achieve 50Mbit/s, but in the next run only 25Mbit/s). In other words: throughput is much better than what we started with in summer, but I think it can be improved further. > I have done simple test of this patchset on RTL8822CE, and it works > well.

I also got feedback off-list from a user who used the patches from this series on top of the out-of-tree rtw88-usb driver. These patches fix one "scheduling while atomic" issue for him as well. Maybe you can do your extensive tests after I sent v3 of this series? Also thanks for offering to test this, I don't have any Realtek PCIe wifi, so I am unable to verify I broke anything myself.
