Subject: [PATCH 3/26 v3] 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.
Signed-off-by: Sean Hefty <sean.hefty@...el.com>
