NAME

       skb_gso_network_seglen - Return length of individual segments of a gso packet

SYNOPSIS

       unsigned int skb_gso_network_seglen(const struct sk_buff * skb);

ARGUMENTS

       skb
	   GSO skb

DESCRIPTION

       skb_gso_network_seglen is used to determine the real size of the individual segments, including Layer3 (IP, IPv6) and L4 headers (TCP/UDP).

       The MAC/L2 header is not accounted for.

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.
