I got your patch working on 4.20-rc5 and did a performance comparison.
With the staging driver (using iperf3) I get
220 MBit/sec in
680 MBit/sec out
with the patched mainline driver I get
190 MBit/sec in
93 MBit/sec out
(numbers are a bit rubbery, but within 10%)
I haven't looked into why this might be, but thought I would mention it.
Strangely when I test with scp, I get about 10MB/sec in both directions
with both drivers. Maybe the CPU limits encryption speed.
I have a 4.4-based kernel where I get 940MBit/sec both ways - using a
precursor of the current staging driver.
Yes, thanks for bringing this up. I should have mentioned that I haven't
considered performance at all yet.
