From 5566386f5f1134c86db82464a4c10656ef1e11fe Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 1 May 2024 16:53:49 +1000 Subject: treewide: Standardise variable names for various packet lengths At various points we need to track the lengths of a packet including or excluding various different sets of headers. We don't always use the same variable names for doing so. Worse in some places we use the same name for different things: e.g. tcp_fill_headers[46]() use ip_len for the length including the IP headers, but then tcp_send_flag() which calls it uses it to mean the IP payload length only. To improve clarity, standardise on these names: dlen: L4 protocol payload length ("data length") l4len: plen + length of L4 protocol header l3len: l4len + length of IPv4/IPv6 header l2len: l3len + length of L2 (ethernet) header Signed-off-by: David Gibson Signed-off-by: Stefano Brivio --- pcap.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'pcap.h') diff --git a/pcap.h b/pcap.h index 15d4657..5339237 100644 --- a/pcap.h +++ b/pcap.h @@ -6,7 +6,7 @@ #ifndef PCAP_H #define PCAP_H -void pcap(const char *pkt, size_t len); +void pcap(const char *pkt, size_t l2len); void pcap_multiple(const struct iovec *iov, size_t frame_parts, unsigned int n, size_t offset); void pcap_iov(const struct iovec *iov, size_t iovcnt); -- cgit v1.2.3
