This patch fixes the rx packet length check in the sunvnet driver to allow
for a TSO max packet length greater than the LDC channel negotiated MTU.
These are negotiated separately and there is no requirement that
port->tsolen be less than port->rmtu, but if it isn't, it'll drop packets
with rx length errors.

The mlx5 driver passes a string pointer in through a 'u64' variable,
which on 32-bit machines causes a build warning:
drivers/net/ethernet/mellanox/mlx5/core/debugfs.c: In function 'qp_read_field':
drivers/net/ethernet/mellanox/mlx5/core/debugfs.c:303:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
The code is in fact safe, so we can shut up the warning by adding
extra type casts.

The rocker driver tries to assign a pointer to a 64-bit integer
and then back to a pointer. This is safe on all architectures,
but causes a compiler warning when pointers are shorter than
64-bit:
rocker/rocker.c: In function 'rocker_desc_cookie_ptr_get':
rocker/rocker.c:809:9: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
return (void *) desc_info->desc->cookie;
^
This adds another cast to uintptr_t to tell the compiler
that it's safe.

Make sure we only allow SR/IOV on the master PF of a port in multifunction
mode. This should be the case anyway based on the num_vfs configured in
the NVM, but this will help make sure there's no question. If we're not
in multifunction mode the partition_id will always be 1.

Previously we were only checking if the link up state had changed,
and if it hadn't exiting the link event routine early. We should
also check if speed has changed, and if it has, stay and finish
processing the link event.

When in NPAR mode the driver instance might be controlling the base
partition or one of the other "fake" PFs. There are some things that
can only be done by the base partition, aka partition_id 1. This code
does a bit of work to find how many partitions are there per port and
what is the current partition_id.

On some versions of the firmware, the VF admin send queue may become
stalled. In this case, the easiest solution is to just place another
descriptor on the queue; the firmware will then process both requests.
The early init code already accounts for this, but the runtime code does
not. In the watchdog task, check for the stall condition, and if it's
found, send our API version to the PF. When the PF replies, just ignore
the reply.

Don't enable vector 0 in the ISR, just schedule the adminq task and let
it enable the vector. This prevents the task from being called
reentrantly. Make sure that the vector is enabled on all exit paths of
the adminq task, including error exits.

There is always a possibility that MSI-X interrupts can get lost. To
keep this problem from stalling the driver, we fire all of our MSI-X
vectors during the watchdog routine. However, we should not fire the
traffic vectors when the interface is closed. In this case, just fire
vector 0, which is used for admin queue events.
As a result, we do not enable the interrupt cause for vector 0. This
can cause the admin queue handler to be called reentrantly, which
causes a scary "critical section violation" message to be logged,
even though no real damage is done.

If we're using VLANs and communications with the PF fail during

be removed. To eliminate this possibility, go through the list again
right before the module is removed and delete any leftover entries.

If the VF driver is running in the host, the shutdown code is completely
broken. We cannot wait in our down routine for the PF to respond to our
requests, as its admin queue task will never run while we hold the lock.
Instead, we schedule operations, then let the watchdog take care of
shutting things down. If the driver is being removed, then wait in the
remove routine until the watchdog is done before continuing.

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.

This patch also changes do_gettimeofday() to ktime_get() accordingly,
since ktime_get returns a ktime_t, but do_gettimeofday returns a

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.

The Freescale mEMAC supports operating at 10/100/1000/10G, and
its associated MDIO controller is likewise capable of operating
both Clause 22 and Clause 45 MDIO buses. It is nearly identical
to the MDIO controller on the XGMAC, so we just modify that
driver.
