85 | * This function is called after the last interface is removed. | ||

87 | * xmit: Handler that 802.15.4 module calls for each transmitted frame. | ||
88 | * skb cntains the buffer starting from the IEEE 802.15.4 header. | ||
89 | * The low-level driver should send the frame based on available | ||
90 | * configuration. | ||
91 | * This function should return zero or negative errno. Called with | ||
92 | * pib_lock held. | ||
93 | * | ||
94 | * ed: Handler that 802.15.4 module calls for Energy Detection. | ||
95 | * This function should place the value for detected energy | ||
96 | * (usually device-dependant) in the level pointer and return | ||
97 | * either zero or negative errno. Called with pib_lock held. | ||
98 | * | ||
99 | * set_channel: | ||
