Port mask now has additional state.
Port can be set as "none". In this case neither the mlx4_en or mlx4_ib
drivers take ownership of the port.
In multifunction mode there is an option to set the vfs as single ported devices.
(in single function mode, both physical ports belong to same function)

These changes will not affect module operation as yet. They
are only to get some structs and enums in place for use by
subsequent patches (making those smaller).

Added here:
* sriov state structs and inlines (mlx4_is_master/slave/mfunc)
* comm-channel and vhcr support structures
* enum values for new FW and comm-channel virtual commands
  (i.e., commands, passed via the comm channel to the PF-driver).
* prototypes for many command wrapper functions (used by the
  PF context for processing FW commands passed to it by the VFs).
* struct mlx4_eqe is moved from eq.c to mlx4.h (it will be used
  by other mlx4_core source files).

- use adapter->num_vfs (and not the module param) to store the actual
number of vfs created. Use the same variable to reflect SRIOV
enable/disable state. So, drop the adapter->sriov_enabled field.

- use for_all_vfs() macro in VF configuration code

- drop the "vf_" prefix for the fields of be_vf_cfg; the prefix is
redundant and removing it helps reduce line wrap

After a guest is live migrated, the xen-netfront driver emits a gratuitous
ARP message, so that networking hardware on the target host's subnet can
take notice, and public routing to the guest is re-established. However,
if the packet appears on the backend interface before the backend is added
to the target host's bridge, the packet is lost, and the migrated guest's
peers become unable to talk to the guest.

A sufficient two-parts condition to prevent the above is:

(1) ensure that the backend only moves to Connected xenbus state after its
hotplug scripts completed, ie. the netback interface got added to the
bridge; and

(2) ensure the frontend only queues the gARP when it sees the backend move
to Connected.

These two together provide complete ordering. Sub-condition (1) is already
satisfied by commit f942dc25 in Linus' tree, based on commit
6b0b80ca7165 from [1].

In general, the full condition is sufficient, not necessary, because,
according to [2], live migration has been working for a long time without
satisfying sub-condition (2). However, after 6b0b80ca7165 was backported
to the RHEL-5 host to ensure (1), (2) still proved necessary in the RHEL-6
guest. This patch intends to provide (2) for upstream.

The Reviewed-by line comes from [3].

The .remove code is broken in several ways.
 - mdiobus_unregister() is called twice for the same object in case of dual FEC
 - phy_disconnect() is being called when the PHY is already disconnected
 - the requested IRQ(s) are not freed
 - fec_stop() is being called with the inteface already stopped

 All of those lead to kernel crashes if the remove function is actually used.

  Currently in ath9k code there is an attempt which is meant to
disable ANI for ar9100 and ar9340. But it doesn't really achieve
this. All it does is disable ANI init and setup (i.e. calls to
ath9k_hw_ani_setup and ath9k_hw_ani_init). Since ath9k_hw_ani_setup is
not called ah->config.ani_poll_interval is never initialized (i.e. it
is always zero) and ath_ani_calibrate always executes ANI procedures
(over uninitialized ANI parameters).
  Moreover, ath_ani_calibrate is being called each 1ms because
common->ani.timer is set to zero interval because
ah->config.ani_poll_interval==0 (and thus smallest value of all
intervals). Normally it should not be called this often.
  This patch changes the code so config.enable_ani is used to check if
ANI should be performed.
  config.enable_ani is initialized to true by default. This patch sets
it to false for ar9100 and ar9340.

Turning off the radio when mac80211 tells the driver that it's idle is not
a good idea, as idle interfaces might still occasionally scan or send packets.
The only time the radio can be safely turned off is when drv_stop has been
called. In the mean time, use sc->ps_idle only to indicate network sleep vs
full sleep.
Move the LED GPIO changes out of the PCI suspend/resume path, the start/stop
functions already take care of that.
