standard section 426 6.2.1.1.2. 427 428 The figure in section 7.1.2 suggests a body size of up to 2312 429 bytes is allowed, which is a bit confusing, I suspect this 430 represents the 2304 bytes of real data, plus a possible 8 bytes of 431 WEP IV and ICV. (this interpretation suggested by Ramiro Barreiro) */ 432#define IEEE80211_1ADDR_LEN 10 433#define IEEE80211_2ADDR_LEN 16 434#define IEEE80211_3ADDR_LEN 24 435#define IEEE80211_4ADDR_LEN 30 436#define IEEE80211_FCS_LEN 4 437#define IEEE80211_HLEN (IEEE80211_4ADDR_LEN) 438#define IEEE80211_FRAME_LEN (IEEE80211_DATA_LEN + IEEE80211_HLEN) 439#define IEEE80211_MGMT_HDR_LEN 24 440#define IEEE80211_DATA_HDR3_LEN 24 441#define IEEE80211_DATA_HDR4_LEN 30 442 443#define MIN_FRAG_THRESHOLD 256U 444#define MAX_FRAG_THRESHOLD 2346U 445 446 447/* Frame control field constants */ 448#define IEEE80211_FCTL_VERS 0x0003 449#define IEEE80211_FCTL_FTYPE 0x000c 450#define IEEE80211_FCTL_STYPE 0x00f0 451#define IEEE80211_FCTL_FRAMETYPE 0x00fc 452#define IEEE80211_FCTL_TODS 0x0100 453#define IEEE80211_FCTL_FROMDS 0x0200 454#define IEEE80211_FCTL_DSTODS 0x0300 //added by david 455#define IEEE80211_FCTL_MOREFRAGS 0x0400 456#define IEEE80211_FCTL_RETRY 0x0800 457#define IEEE80211_FCTL_PM 0x1000 458#define IEEE80211_FCTL_MOREDATA 0x2000 459#define IEEE80211_FCTL_WEP 0x4000 460#define IEEE80211_FCTL_ORDER 0x8000 461 462#define IEEE80211_FTYPE_MGMT 0x0000 463#define IEEE80211_FTYPE_CTL 0x0004 464#define IEEE80211_FTYPE_DATA 0x0008 465 466/* management */ 467#define IEEE80211_STYPE_ASSOC_REQ 0x0000 468#define IEEE80211_STYPE_ASSOC_RESP 0x0010 469#define IEEE80211_STYPE_REASSOC_REQ 0x0020 470#define IEEE80211_STYPE_REASSOC_RESP 0x0030 471#define IEEE80211_STYPE_PROBE_REQ 0x0040 472#define IEEE80211_STYPE_PROBE_RESP 0x0050 473#define IEEE80211_STYPE_BEACON 0x0080 474#define IEEE80211_STYPE_ATIM 0x0090 475#define IEEE80211_STYPE_DISASSOC 0x00A0 476#define IEEE80211_STYPE_AUTH 0x00B0 477#define IEEE80211_STYPE_DEAUTH 0x00C0 478#define IEEE80211_STYPE_MANAGE_ACT 0x00D0 479 480/* control */ 481#define IEEE80211_STYPE_PSPOLL 0x00A0 482#define IEEE80211_STYPE_RTS 0x00B0 483#define IEEE80211_STYPE_CTS 0x00C0 484#define IEEE80211_STYPE_ACK 0x00D0 485#define IEEE80211_STYPE_CFEND 0x00E0 486#define IEEE80211_STYPE_CFENDACK 0x00F0 487#define IEEE80211_STYPE_BLOCKACK 0x0094 488 489/* data */ 490#define IEEE80211_STYPE_DATA 0x0000 491#define IEEE80211_STYPE_DATA_CFACK 0x0010 492#define IEEE80211_STYPE_DATA_CFPOLL 0x0020 493#define IEEE80211_STYPE_DATA_CFACKPOLL 0x0030 494#define IEEE80211_STYPE_NULLFUNC 0x0040 495#define IEEE80211_STYPE_CFACK 0x0050 496#define IEEE80211_STYPE_CFPOLL 0x0060 497#define IEEE80211_STYPE_CFACKPOLL 0x0070 498#define IEEE80211_STYPE_QOS_DATA 0x0080 //added for WMM 2006/8/2 499#define IEEE80211_STYPE_QOS_NULL 0x00C0 500 501#define IEEE80211_SCTL_FRAG 0x000F 502#define IEEE80211_SCTL_SEQ 0xFFF0 503 504/* QOS control */ 505#define IEEE80211_QCTL_TID 0x000F 506 507#define FC_QOS_BIT BIT7 508#define IsDataFrame(pdu) ( ((pdu[0] & 0x0C)==0x08) ? true : false ) 509#define IsLegacyDataFrame(pdu) (IsDataFrame(pdu) && (!(pdu[0]&FC_QOS_BIT)) ) 510//added by wb.
