NAME
       skb_pull_rcsum - pull skb and update receive checksum

SYNOPSIS
       unsigned char * skb_pull_rcsum(struct sk_buff * skb, unsigned int len);

ARGUMENTS
       skb
	   buffer to update

       len
	   length of data pulled

DESCRIPTION
       This function performs an skb_pull on the packet and updates the
       CHECKSUM_COMPLETE checksum. It should be used on receive path
       processing instead of skb_pull unless you know that the checksum
       difference is zero (e.g., a valid IP header) or you are setting
       ip_summed to CHECKSUM_NONE.
