skb_partial_csum_set - set up and verify partial csum values for packet SYNOPSIS
bool skb_partial_csum_set(struct sk_buff * skb, u16 start, u16 off); ARGUMENTS
skb the skb to set start the number of bytes after skb->data to start checksumming. off the offset from start to place the checksum. DESCRIPTION
For untrusted partially-checksummed packets, we need to make sure the values for skb->csum_start and skb->csum_offset are valid so we don't oops. This function checks and sets those values and skb->ip_summed: if this returns false you should drop the packet. COPYRIGHT

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. COPYRIGHT
