Thanks Jakub this looks reasonable to me I'm going to run some tests
with sockmap + ktls on it this weekend to be sure the two work
together with some of our applications. I believe the original
series should be enough so that BPF can be safely unloaded out
from underneath ktls now.
I guess we could do something similar on the sockmap side but I
do want to loosen the restrictions there at some point so might
be best just to keep it as is.
Thanks,
John
