/* The meaning and bit positions used in "opaque_data" field in ECOM implementation

 0 0 0 0 0 0 0 0 ---->All 0 means allowed both inside (encapsulated EAP) and outside (Outer EAP)

 | | | | | | | |

 | | | | | | | |_____ 1 means NOT_INSIDE_TUNNEL (NOT allowed as encapsulated EAP)

 | | | | | | |

 | | | | | | |_______ 1 means NOT_OUTSIDE_TUNNEL (only allowed as encapsulated EAP, NOT as outer EAP)

 | | | | | |  

 | | | | | |_________ 1 means NOT_INSIDE_PEAP

 | | | | |  

 | | | | |___________ 1 means NOT_OUTSIDE_PEAP  

 | | | | 

 | | | |_____________ 1 means NOT_INSIDE_TTLS

 | | | 

 | | |_______________ 1 means NOT_OUTSIDE_TTLS

 | | 

 | |_________________ 1 means NOT_INSIDE_FAST

 |

 |___________________ 1 means NOT_OUTSIDE_FAST

 // For historical reasons NOT_OUTSIDE_PEAP is used instead of NOT_OUTSIDE_TUNNEL

 // Both of these convey the same meaning. It means if an EAP is not allowed outside PEAP

 // (DisallowedOutsidePEAP), it can be used only as an encapsulated EAP.

 // EAP-MSCHAPv2 is an example for this.

 // The bits can be ORed. 

 // "NOT_OUTSIDE|NOT_OUTSIDE_PEAP" is 0x0A (0000 1010).

 // "NOT_OUTSIDE|NOT_OUTSIDE_PEAP|NOT_INSIDE_PEAP|NOT_INSIDE_FAST" is 0x4E (0100 1110).

 // "NOT_INSIDE|NOT_INSIDE_PEAP|NOT_INSIDE_TTLS|NOT_INSIDE_FAST" is 0x55 (0101 0101).

 // "NOT_INSIDE|NOT_INSIDE_PEAP|NOT_INSIDE_TTLS|NOT_INSIDE_FAST|NOT_OUTSIDE_PEAP|NOT_OUTSIDE" is 0x5F (0101 1111).
