auth: fix CHAP challenge with ixia
here is the structure of CHAP challenge message for PPP:
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Code | Identifier | Length |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Value-Size | Value ...
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Name ...
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
When sending a CHAP challenge, accel-ppp set NAME to NULL. According to
RFC 1994 (PPP CHAP), this field should neither be NULL nor be equal to
CR/LF. As ixia does not recognize AUthentication packet when this field
is NULL, we set it to "accel-ppp" by default.
In MS-CHAPv1 and MS-CHAPv2, authenticator does not provide information
in Name field.
