函数原型：static inline __sum16 __skb_checksum_validate_complete(struct sk_buff *skb, bool complete, __wsum psum)

返回类型：__sum16

参数：

类型参数名称
struct sk_buff *skb
boolcomplete
__wsumpsum
3946  如果ip_summed恒等于CHECKSUM_COMPLETE则
3947  如果非Fold a partial checksum则
3948  csum_valid等于1
3949  返回:0
3953  csum等于psum
3955  如果complete或len小于等于For small packets <= CHECKSUM_BREAK perform checksum complete directly* in checksum_init.则
3958  csum等于__skb_checksum_complete(skb)
3959  csum_valid等于非csum
3960  返回:csum
3963  返回:0
