Name:locally generated TCP pure ACKs have skb->truesize == 2* (check tcp_send_ack() in net/ipv4/tcp_output.c )* This is much faster than dissecting the packet to find out.* (Think of GRE encapsulations, IPv4, IPv6, ...)
Proto:static inline bool skb_is_tcp_pure_ack(const struct sk_buff *skb)
Type:bool
Parameter:
| Type | Parameter | Name |
|---|---|---|
| const struct sk_buff * | skb |
| 2077 | Return truesize == 2 |
