From d05091db1d58d82a2d4c3cb7c1d505fd42a0a13f Mon Sep 17 00:00:00 2001 From: bz Date: Sat, 11 Feb 2012 06:02:16 +0000 Subject: Introduce a new NET_RT_IFLISTL API to query the address list. It works on extended and extensible structs if_msghdrl and ifa_msghdrl. This will allow us to extend both the msghdrl structs and eventually if_data in the future without breaking the ABI. Bump __FreeBSD_version to allow ports to more easily detect the new API.
