I'm not sure what you mean by this.  Do you mean creating some tests that
sit directly on top of the kernel and test the kernel parts (e.g., use
netlink)?  If so, that would be useful but you may end up implementing
some of the NFC stack.  If you mean more/better tests that use neard to
exercise the whole stack then that would be really good too.

Speaking of NFC stack, the NFC forum has their specs paywalled which is
a real bummer/pain.  I can try reaching out to them to see if they will
help us help their mission but I'm not hopeful.

FYI, most of the issues that I ran into and know still exist are
timing/race issues in neard.  I'm sure if we tested more, we could find
some in the kernel though.
