Because this bit applies only to foreign 276*7c478bd9Sstevel@tonic-gate * agents, an agent MUST NOT set the 'R' bit to one unless the 'F' 277*7c478bd9Sstevel@tonic-gate * bit is also set to one. 278*7c478bd9Sstevel@tonic-gate */ 279*7c478bd9Sstevel@tonic-gate #ifdef __sparc 280*7c478bd9Sstevel@tonic-gate #ifdef _BIT_FIELDS_HTOL 281*7c478bd9Sstevel@tonic-gate typedef struct mobility_agt_adv_extension { 282*7c478bd9Sstevel@tonic-gate uchar_t type; 283*7c478bd9Sstevel@tonic-gate uchar_t length; 284*7c478bd9Sstevel@tonic-gate ushort_t sequence_num; 285*7c478bd9Sstevel@tonic-gate ushort_t reg_lifetime; 286*7c478bd9Sstevel@tonic-gate ushort_t reg_bit:1, 287*7c478bd9Sstevel@tonic-gate busy_bit:1, 288*7c478bd9Sstevel@tonic-gate ha_bit:1, 289*7c478bd9Sstevel@tonic-gate fa_bit:1, 290*7c478bd9Sstevel@tonic-gate minencap_bit:1, 291*7c478bd9Sstevel@tonic-gate greencap_bit:1, 292*7c478bd9Sstevel@tonic-gate vanjacob_hdr_comp_bit:1, 293*7c478bd9Sstevel@tonic-gate reverse_tunnel_bit:1, 294*7c478bd9Sstevel@tonic-gate reserved:8; 295*7c478bd9Sstevel@tonic-gate } mobagtadvext_t; 296*7c478bd9Sstevel@tonic-gate 297*7c478bd9Sstevel@tonic-gate #endif /* _BIT_FIELDS_HTOL */ 298*7c478bd9Sstevel@tonic-gate #endif /* __sparc */ 299*7c478bd9Sstevel@tonic-gate 300*7c478bd9Sstevel@tonic-gate #ifdef __i386 301*7c478bd9Sstevel@tonic-gate #ifdef _BIT_FIELDS_LTOH 302*7c478bd9Sstevel@tonic-gate typedef struct mobility_agt_adv_extension { 303*7c478bd9Sstevel@tonic-gate uchar_t type; 304*7c478bd9Sstevel@tonic-gate uchar_t length; 305*7c478bd9Sstevel@tonic-gate ushort_t sequence_num; 306*7c478bd9Sstevel@tonic-gate ushort_t reg_lifetime; 307*7c478bd9Sstevel@tonic-gate uchar_t 308*7c478bd9Sstevel@tonic-gate reverse_tunnel_bit:1, 309*7c478bd9Sstevel@tonic-gate vanjacob_hdr_comp_bit:1, 310*7c478bd9Sstevel@tonic-gate greencap_bit:1, 311*7c478bd9Sstevel@tonic-gate minencap_bit:1, 312*7c478bd9Sstevel@tonic-gate fa_bit:1, 313*7c478bd9Sstevel@tonic-gate ha_bit:1, 314*7c478bd9Sstevel@tonic-gate busy_bit:1, 315*7c478bd9Sstevel@tonic-gate reg_bit:1; 316*7c478bd9Sstevel@tonic-gate uchar_t reserved; 317*7c478bd9Sstevel@tonic-gate } mobagtadvext_t; 318*7c478bd9Sstevel@tonic-gate #endif /* _BIT_FIELDS_LTOH */ 319*7c478bd9Sstevel@tonic-gate #endif /* __i386 */ 320*7c478bd9Sstevel@tonic-gate 321*7c478bd9Sstevel@tonic-gate #ifdef __cplusplus 322*7c478bd9Sstevel@tonic-gate } 323*7c478bd9Sstevel@tonic-gate #endif 324*7c478bd9Sstevel@tonic-gate 325*7c478bd9Sstevel@tonic-gate #endif /* _SNOOP_MIP_H */ 326
