Subject: [Patch net-next 1/7] net: introduce generic union inet_addr
From: Cong Wang <amwang@...hat.com>
Introduce a generic IP address type, union inet_addr, so that
subsystems don't have to use their own definitions. Because
netpoll already defines union inet_addr, just move it to global.
Some of the helper functions will be used by VXLAN IPv6 code too.
This patch also reuses the "%pIS" specifier, to make it accept
union inet_addr instead of struct sockaddr.
