IEEE80211_RX_IRQSAFE(9) 				  The basic mac80211 driver inte				   IEEE80211_RX_IRQSAFE(9)

NAME

       ieee80211_rx_irqsafe - receive frame

SYNOPSIS

       void ieee80211_rx_irqsafe(struct ieee80211_hw * hw, struct sk_buff * skb);

ARGUMENTS

       hw
	   the hardware this frame came in on

       skb
	   the buffer to receive, owned by mac80211 after this call

DESCRIPTION

       Like ieee80211_rx but can be called in IRQ context (internally defers to a tasklet.)

       Calls to this function, ieee80211_rx or ieee80211_rx_ni may not be mixed for a single hardware.

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_TSFT,
	 RX_FLAG_SHORTPRE,
	 RX_FLAG_HT,
	 RX_FLAG_40MHZ,
	 RX_FLAG_SHORT_GI,
	 RX_FLAG_INTERNAL_CMTR
       };

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_TSFT
	   The timestamp passed in the RX status (mactime field) is valid. This is useful in monitor mode and necessary for beacon frames to
	   enable 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_INTERNAL_CMTR
	   set internally after frame was reported on cooked monitor to avoid double-reporting it for multiple virtual interfaces

DESCRIPTION

       These flags are used with the flag member of struct ieee80211_rx_status.
