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.
