skb_pull_rcsum(9)
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.
