'''
11/26/2015 disable tc_login_11_2 and tc_login_11_4
RFC 7143 6.3
Neither the initiator nor the target should attempt to declare or
negotiate a parameter more than once during login, except for
responses to specific keys that explicitly allow repeated key
declarations (e.g., TargetAddress)

The spec didn't make it clear what other keys could be re-declare
Disscussed this with UNH and get the conclusion that TargetName/
TargetAddress/MaxRecvDataSegmentLength could be re-declare.

12/1/2015 add tc_login_2_2 to known_failed_cases

A standard-label MUST begin with a capital letter and must not exceed
