Hi Folks,

This is a follow up for http://www.spinics.net/lists/linux-rdma/msg44536.html.
As Jason suggested, I'm moving 4 elments for per port arrays into a seperate
ib_port_cache structure.

Please apply after the first 4 patches.

Subject: [PATCH 1/1] IB/core: create struct ib_port_cache

As Jason suggested, we have 4 elements for per port arrays,
it's better to have a seperate structure to represent them.

That isn't really what I ment..

struct ib_port_cache {
   enum ib_port_state port_state;
   struct ib_pkey_cache *pkey;
   struct ib_gid_table *gid;
   u8 lmc;
};

struct ib_cache {
   struct ib_port_cache *ports;
};
