The 337da14cebeSEric Cheng * structure represents the undelying hardware, in terms of definition, 338da14cebeSEric Cheng * resources (transmit, receive rings etc.), callback functions etc. It 339da14cebeSEric Cheng * also holds the table of MAC clients that are configured on the device. 340da14cebeSEric Cheng * The table is used for classifying incoming packets in software. 341da14cebeSEric Cheng * 342da14cebeSEric Cheng * The protection scheme uses 2 elements, a coarse serialization mechanism 343da14cebeSEric Cheng * called perimeter and a finer traditional lock based scheme. More details 344da14cebeSEric Cheng * can be found in the big block comment in mac.c. 345da14cebeSEric Cheng * 346da14cebeSEric Cheng * The protection scheme for each member of the mac_impl_t is described below. 347da14cebeSEric Cheng * 348da14cebeSEric Cheng * Write Once Only (WO): Typically these don't change for the lifetime of the 349da14cebeSEric Cheng * data structure. For example something in mac_impl_t that stays the same 350da14cebeSEric Cheng * from mac_register to mac_unregister, or something in a mac_client_impl_t 351da14cebeSEric Cheng * that stays the same from mac_client_open to mac_client_close. 352da14cebeSEric Cheng * 353da14cebeSEric Cheng * Serializer (SL): Protected by the Serializer. All SLOP operations on a 354da14cebeSEric Cheng * mac endpoint go through the serializer. MTOPs don't care about reading 355da14cebeSEric Cheng * these fields atomically. 356da14cebeSEric Cheng * 357da14cebeSEric Cheng * Lock: Traditional mutex/rw lock. Modify operations still go through the 358da14cebeSEric Cheng * mac serializer, the lock helps synchronize readers with writers. 359da14cebeSEric Cheng */ 360da14cebeSEric Cheng struct mac_impl_s { 361da14cebeSEric Cheng krwlock_t mi_rw_lock; 362c228408bSMichael Lim list_node_t mi_node; 363da14cebeSEric Cheng char mi_name[LIFNAMSIZ]; /* WO */ 364da14cebeSEric Cheng uint32_t mi_state_flags; 365da14cebeSEric Cheng void *mi_driver; /* Driver private, WO */ 366da14cebeSEric Cheng mac_info_t mi_info; /* WO */ 367da14cebeSEric Cheng mactype_t *mi_type; /* WO */ 368da14cebeSEric Cheng void *mi_pdata; /* WO */ 369da14cebeSEric Cheng size_t mi_pdata_size; /* WO */ 370da14cebeSEric Cheng mac_callbacks_t *mi_callbacks; /* WO */ 371da14cebeSEric Cheng dev_info_t *mi_dip; /* WO */ 372da14cebeSEric Cheng uint32_t mi_ref; /* i_mac_impl_lock */ 373da14cebeSEric Cheng uint_t mi_active; /* SL */ 374da14cebeSEric Cheng link_state_t mi_linkstate; /* none */ 3754eaa4710SRishi Srivatsavai link_state_t mi_lowlinkstate; /* none */ 3764eaa4710SRishi Srivatsavai link_state_t mi_lastlowlinkstate; /* none */ 377da14cebeSEric Cheng uint_t mi_devpromisc; /* SL */ 378da14cebeSEric Cheng uint8_t mi_addr[MAXMACADDRLEN]; /* mi_rw_lock */ 379da14cebeSEric Cheng uint8_t mi_dstaddr[MAXMACADDRLEN]; /* mi_rw_lock */ 3802b24ab6bSSebastien Roy boolean_t mi_dstaddr_set; 381d62bc4baSyz147064 382da14cebeSEric Cheng /* 383da14cebeSEric Cheng * The mac perimeter.
