The cover letter didn't make it to netdev so replying here -
please add test cases for EOR to tools/testing/selftests/net/tls.c
(FWIW selftests now take command line arguments allowing you to narrow
down the set of test cases run, it's pretty useful here, waiting for
all crypto algos to finish is annoying)
