函数名称：sock_recv_timestamp

函数原型：static inline void sock_recv_timestamp(struct msghdr *msg, struct sock *sk, struct sk_buff *skb)

返回类型：void

参数：

类型参数名称
struct msghdr *msg
struct sock *sk
struct sk_buff *skb
2372  kt等于tstamp
2373  hwtstamps等于skb_hwtstamps(skb)
2381  如果sock_flag(sk, %SO_TIMESTAMP setting )或sk_tsflags按位与SOF_TIMESTAMPING_RX_SOFTWARE或kt且sk_tsflags按位与SOF_TIMESTAMPING_SOFTWARE或hwtstamp且sk_tsflags按位与SOF_TIMESTAMPING_RAW_HARDWARE则__sock_recv_timestamp(msg, sk, skb)
2387  否则sock_write_timestamp(sk, kt)
2390  如果sock_flag(sk, push wifi status to userspace )且wifi_acked_valid则__sock_recv_wifi_status(msg, sk, skb)
