NAME¶

wimax_msg_send - Send a pre-allocated message to user space

SYNOPSIS¶

int wimax_msg_send(struct wimax_dev * wimax_dev, struct sk_buff * skb);

ARGUMENTS¶

wimax_dev

skb

RETURNS¶

0 if ok, < 0 errno code on error

DESCRIPTION¶

Sends a free-form message that was preallocated with wimax_msg_alloc and filled up.

Assumes that once you pass an skb to this function for sending, it owns it and will release it when done (on success).

IMPORTANT¶

Don't use skb_push/skb_pull/skb_reserve on the skb, as wimax_msg_send depends on skb->data being placed at the beginning of the user message.

Unlike other WiMAX stack calls, this call can be used way early, even before wimax_dev_add is called, as long as the wimax_dev->net_dev pointer is set to point to a proper net_dev. This is so that drivers can use it early in case they need to send stuff around or communicate with user space.
