MCS MyVoIP 8.2b (Default branch)
01-27-2009
MCS MyVoIP very accurately measures the quality and performance of Internet connections for Voice over IP (VoIP) usage by simulating UDP voice data traffic between a server and browser clients. Connections are tested for jitter and packet loss and rated for the supported level of sound quality. The VoIP test can be set to various codecs or customized by packet size, packet rate, and test length. The test can further be combined with a bandwidth speed test or network route diagnostics for more in-depth connection analysis. License: Other/Proprietary License with Free Trial Changes:|

MAC80211_RX_FLA(9) The basic mac80211 driver inte ENUM MAC80211_RX_FLA(9) NAME
enum_mac80211_rx_flags - receive flags SYNOPSIS
enum mac80211_rx_flags { RX_FLAG_MMIC_ERROR, RX_FLAG_DECRYPTED, RX_FLAG_MMIC_STRIPPED, RX_FLAG_IV_STRIPPED, RX_FLAG_FAILED_FCS_CRC, RX_FLAG_FAILED_PLCP_CRC, RX_FLAG_MACTIME_START, RX_FLAG_SHORTPRE, RX_FLAG_HT, RX_FLAG_40MHZ, RX_FLAG_SHORT_GI, RX_FLAG_NO_SIGNAL_VAL, RX_FLAG_HT_GF, RX_FLAG_AMPDU_DETAILS, RX_FLAG_AMPDU_REPORT_ZEROLEN, RX_FLAG_AMPDU_IS_ZEROLEN, RX_FLAG_AMPDU_LAST_KNOWN, RX_FLAG_AMPDU_IS_LAST, RX_FLAG_AMPDU_DELIM_CRC_ERROR, RX_FLAG_AMPDU_DELIM_CRC_KNOWN, RX_FLAG_MACTIME_END, RX_FLAG_VHT, RX_FLAG_80MHZ, RX_FLAG_80P80MHZ, RX_FLAG_160MHZ }; CONSTANTS
RX_FLAG_MMIC_ERROR Michael MIC error was reported on this frame. Use together with RX_FLAG_MMIC_STRIPPED. RX_FLAG_DECRYPTED This frame was decrypted in hardware. RX_FLAG_MMIC_STRIPPED the Michael MIC is stripped off this frame, verification has been done by the hardware. RX_FLAG_IV_STRIPPED The IV/ICV are stripped from this frame. If this flag is set, the stack cannot do any replay detection hence the driver or hardware will have to do that. RX_FLAG_FAILED_FCS_CRC Set this flag if the FCS check failed on the frame. RX_FLAG_FAILED_PLCP_CRC Set this flag if the PCLP check failed on the frame. RX_FLAG_MACTIME_START The timestamp passed in the RX status (mactime field) is valid and contains the time the first symbol of the MPDU was received. This is useful in monitor mode and for proper IBSS merging. RX_FLAG_SHORTPRE Short preamble was used for this frame RX_FLAG_HT HT MCS was used and rate_idx is MCS index RX_FLAG_40MHZ HT40 (40 MHz) was used RX_FLAG_SHORT_GI Short guard interval was used RX_FLAG_NO_SIGNAL_VAL The signal strength value is not present. Valid only for data frames (mainly A-MPDU) RX_FLAG_HT_GF This frame was received in a HT-greenfield transmission, if the driver fills this value it should add IEEE80211_RADIOTAP_MCS_HAVE_FMT to hw.radiotap_mcs_details to advertise that fact RX_FLAG_AMPDU_DETAILS A-MPDU details are known, in particular the reference number (ampdu_reference) must be populated and be a distinct number for each A-MPDU RX_FLAG_AMPDU_REPORT_ZEROLEN driver reports 0-length subframes RX_FLAG_AMPDU_IS_ZEROLEN This is a zero-length subframe, for monitoring purposes only RX_FLAG_AMPDU_LAST_KNOWN last subframe is known, should be set on all subframes of a single A-MPDU RX_FLAG_AMPDU_IS_LAST this subframe is the last subframe of the A-MPDU RX_FLAG_AMPDU_DELIM_CRC_ERROR A delimiter CRC error has been detected on this subframe RX_FLAG_AMPDU_DELIM_CRC_KNOWN The delimiter CRC field is known (the CRC is stored in the ampdu_delimiter_crc field) RX_FLAG_MACTIME_END The timestamp passed in the RX status (mactime field) is valid and contains the time the last symbol of the MPDU (including FCS) was received. RX_FLAG_VHT VHT MCS was used and rate_index is MCS index RX_FLAG_80MHZ 80 MHz was used RX_FLAG_80P80MHZ 80+80 MHz was used RX_FLAG_160MHZ 160 MHz was used DESCRIPTION
These flags are used with the flag member of struct ieee80211_rx_status. AUTHOR
