I seem to be unable to reproduce this either on x86_64 or on an embedded
MIPS device with OpenWRT. Did you figure out what the problem was or is
this still an open issue? Which supplicant was used in the test? And
the same questions would apply for the "EAP-PEAP: Unexpected
Cryptobinding TLV SubType 0", too.
