Synopsis
unsigned char * skb_push_rcsum ( | struct sk_buff * skb, |
| | unsigned int len); |
Arguments
struct sk_buff * skb

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