WIMAX_MSG_SEND(9)

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
    WiMAX device descriptor

skb
    struct sk_buff returned by wimax_msg_alloc. Note the ownership of skb is transferred to this function.

RETURN

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.
