void ieee80211_rx	(	struct ieee80211_hw *	hw,
		struct sk_buff *	skb
	)

ieee80211_rx - receive frame

Use this function to hand received frames to mac80211. The receive buffer in must start with an IEEE 802.11 header. In case of a paged is used, the driver is recommended to put the ieee80211 header of the frame on the linear part of the to avoid memory allocation and/or memcpy by the stack.

This function may not be called in IRQ context. Calls to this function for a single hardware must be synchronized against each other. Calls to this function, ieee80211_rx_ni() and ieee80211_rx_irqsafe() may not be mixed for a single hardware.

In process context use instead ieee80211_rx_ni().

: the hardware this frame came in on : the buffer to receive, owned by mac80211 after this call

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

ieee80211_rx_irqsafe - receive frame

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.

int ieee80211_sta_ps_transition	(	struct ieee80211_sta *	sta,
		bool	start
	)

ieee80211_sta_ps_transition - PS transition for connected sta

When operating in AP mode with the IEEE80211_HW_AP_LINK_PS flag set, use this function to inform mac80211 about a connected station entering/leaving PS mode.

This function may not be called in IRQ context or with softirqs enabled.

Calls to this function for a single hardware must be synchronized against each other.

The function returns -EINVAL when the requested PS mode is already set.

: currently connected sta : start or stop PS
