.RE
.SH "DESCRIPTION"
.PP
.PP
Use this function to hand received frames to mac80211\&. The receive buffer in
\fIskb\fR
must start with an IEEE 802\&.11 header\&. In case of a paged
\fIskb\fR
is used, the driver is recommended to put the ieee80211 header of the frame on the linear part of the
\fIskb\fR
to avoid memory allocation and/or memcpy by the stack\&.
.PP
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,
\fBieee80211_rx_ni\fR
and
\fBieee80211_rx_irqsafe\fR
may not be mixed for a single hardware\&. Must not run concurrently with
\fBieee80211_tx_status\fR
or
\fBieee80211_tx_status_ni\fR\&.
.PP
In process context use instead
\fBieee80211_rx_ni\fR\&.
