Subject: [Patch net-next 6/7] sctp: use generic union inet_addr
From: Cong Wang <amwang@...hat.com>
sctp has its own union sctp_addr which is nearly same
with the generic union inet_addr, so just convert it
to the generic one.
Sorry for the big patch, it is not easy to split it. Most
of the patch simply does s/union sctp_addr/union inet_addr/
and some adjustments for the fields.
The address family specific ops, ->cmp_addr(), ->is_any() etc.,
are removed, since we have generic helpers, they are unnecessary.
