NAME

ieee80211_rx - receive frame

SYNOPSIS

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

ARGUMENTS

: the hardware this frame came in on

skb

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

DESCRIPTION

Use this function to hand received frames to mac80211. The receive buffer in skb must start with an IEEE 802.11 header. In case of a paged skb is used, the driver is recommended to put the ieee80211 header of the frame on the linear part of the skb 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.
