Subject: [PATCH ulogd2 v3 03/11] printpkt, raw2packet_BASE: keep gateway address in NBO
Date: Mon, 21 Aug 2023 20:42:29 +0100	[thread overview]
Message-ID: <20230821194237.51139-4-jeremy@azazel.net> (raw)
In-Reply-To: <20230821194237.51139-1-jeremy@azazel.net>

Everywhere else ipv4 addresses are left in NBO until output.  The only
exception is the IP2HBIN filter, which is explicitly intended to convert
from NBO to HBO.
