From ef560861c01c301cde3da154eb9c1c2619924c3a Mon Sep 17 00:00:00 2001 From: Sean Hefty Date: Wed, 29 May 2013 10:09:10 -0700 Subject: [PATCH] IB/addr: Add AF_IB support to ip_addr_size Add support for AF_IB to ip_addr_size, and rename the function to account for the change. Give the compiler more control over whether the call should be inline or not by moving the definition into the .c file, removing the static inline, and exporting it.
