These messages may be triggered during normal init of the driver if the
PF or FW take a long time to respond. There's nothing really wrong, so
don't freak people out logging messages.

If the communication channel really is dead, then we'll retry a few
times and give up. This will log a different more scary message that
should cause consternation. This allows the user to more easily detect a
genuine failure.

If VF drivers are loaded in the host OS, the call to pci_disable_sriov()
will cause these drivers' remove routines to be called. If the PF driver
has already freed VF resources before this happens, then the VF remove
routine can't properly communicate with the PF driver causing all sorts
of mayhem and error messages and hurt feelings.

To fix this, we move the call to pci_disable_sriov() up to the top of
the function and let it complete before freeing any VF resources.

Networking under kvm works best if we allocate a per-vCPU RX and TX
queue in a virtual NIC. This requires a per-vCPU queue on the host side.

It is now safe to increase the maximum number of queues.
Preceding patch: 'net: allow large number of rx queues'
made sure this won't cause failures due to high order memory
allocations. Increase it to 256: this is the max number of vCPUs
KVM supports.

Size of tun_struct changes from 8512 to 10496 after this patch. This keeps
pages allocated for tun_struct before and after the patch to 3.

Remove the empty array element initializer and size the array with
BOND_OPT_LAST so the compiler will complain if more elements are in
there than should be.

An interesting unwanted side effect of this initializer is that if one
inserts new options into the middle of the array then this initializer
will zero out the option that equals BOND_OPT_TLB_DYNAMIC_LB+1.

Example:
Extend the OPTS enum:
enum {
   ...
   BOND_OPT_TLB_DYNAMIC_LB,
   BOND_OPT_LACP_NEW1,
   BOND_OPT_LAST
};

Now insert into bond_opts array:
static const struct bond_option bond_opts[] = {
      ...
      [BOND_OPT_LACP_RATE] = { .... unchanged stuff .... },
      [BOND_OPT_LACP_NEW1] = { ... new stuff ... },
      ...
      [BOND_OPT_TLB_DYNAMIC_LB] = { .... unchanged stuff ....},
      { } // MARK A
};

Since BOND_OPT_LACP_NEW1 = BOND_OPT_TLB_DYNAMIC_LB+1, the last
initializer (MARK A) will overwrite the contents of BOND_OPT_LACP_NEW1
and can be easily viewed with the crash utility.

The vlsi ir driver uses 'timeval', which we try to remove in the kernel
because all 32-bit time types will break in the year 2038.

This patch also changes do_gettimeofday() to ktime_get() accordingly,
since ktime_get returns a ktime_t, but do_gettimeofday returns a
struct timeval, and the other reason is that ktime_get() uses
the monotonic clock.

This patch uses ktime_us_delta to get the elapsed time of microsecond,
and uses div_s64_rem to get what seconds & microseconds time elapsed
for printing.

This patch also changes the function 'vlsi_hard_start_xmit' to do the
same things as the others drivers, that is passing the remaining time
into udelay() instead of looping until enough time has passed.

Based on Arnds review comments here https://lkml.org/lkml/2014/11/13/161,
we should not be mixing address spaces in the reg property like this driver
currently does. This patch updates the driver, dt docs and also the existing
dt nodes to pass the sysconfig offset in the syscon dt property.

This patch breaks DT compatibility! But this platform is considered WIP,
and is only used by a few developers who are upstreaming support for it.
This change has been done as a single atomic commit to ensure it is
bisectable.
