From 39232973b779ab0c02cb6dcd8f819b7cb0fcd09a Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 26 Jan 2012 15:22:32 -0500 Subject: ipv4/ipv6: Prepare for new route gateway semantics. In the future the ipv4/ipv6 route gateway will take on two types of values: 1) INADDR_ANY/IN6ADDR_ANY, for local network routes, and in this case the neighbour must be obtained using the destination address in ipv4/ipv6 header as the lookup key. 2) Everything else, the actual nexthop route address. So if the gateway is not inaddr-any we use it, otherwise we must use the packet's destination address. Signed-off-by: David S.

Convert a printk block to print_hex_dump. Coalesce formats, align arguments. Use %s, __func__ instead of embedding function names. Some messages that were prefixed with _close are now prefixed with _fini. Some ah4 and esp messages are now not prefixed with "ip ". The intent of this patch is to later add something like #define pr_fmt(fmt) "IPv4: " fmt. to standardize the output messages. Text size is trivially reduced.
