From 9c25eb1f4876a399919782c97e116732ea2ee628 Mon Sep 17 00:00:00 2001 From: Filip Varga Date: Thu, 21 Oct 2021 13:00:27 +0200 Subject: nat: api autoendian fix Fixed bad use of macros for autoendian API calls and updated tests for the new API. Removed sw_if_index check macro because of ntol conversion. Changed REPLY_MACRO to REPLY_MACRO_END to fix ntohl conversions.
