consume_skb - free an skbuff
SYNOPSIS
void consume_skb(struct sk_buff * skb);
ARGUMENTS
skb
buffer to free
DESCRIPTION
Drop a ref to the buffer and free it if the usage count has hit zero Functions identically to kfree_skb, but kfree_skb assumes that the
frame is being dropped after a failure and notes that

WIMAX_MSG_ALLOC(9) Linux Networking WIMAX_MSG_ALLOC(9)NAME
wimax_msg_alloc - Create a new skb for sending a message to userspace
SYNOPSIS
struct sk_buff * wimax_msg_alloc(struct wimax_dev * wimax_dev, const char * pipe_name, const void * msg, size_t size, gfp_t gfp_flags);
ARGUMENTS
wimax_dev
WiMAX device descriptor
pipe_name
"named pipe" the message will be sent to
msg
pointer to the message data to send
size
size of the message to send (in bytes), including the header.
gfp_flags
flags for memory allocation.
RETURNS
0 if ok, negative errno code on error
DESCRIPTION
Allocates an skb that will contain the message to send to user space over the messaging pipe and initializes it, copying the payload.
Once this call is done, you can deliver it with wimax_msg_send.
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.
