Any progress on this? I'm almost ready to do a v4.00 release of
OpenConnect with fully functional GnuTLS support (including PKCS#11 and
TPM). I might disable the automatic setting of base-mtu from TCP_INFO
data, since it's not working, and just leave you with the command line
option for it until we work out a better way to detect it.
