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.

The deleted lines are called from a function which is called:
1) Only through __team_options_register via team_options_register and
2) Only during initialization / mode initialization when there are no
ports attached.
Therefore the ports list is guarenteed to be empty and this code will
never be executed.

Commit e4c7f259c5 ("USB: kaweth.c: use GFP_ATOMIC under spin_lock")
makes sure that kaweth_internal_control_msg() allocates memory with GFP_ATOMIC,
but kaweth_internal_control_msg() also calls usb_start_wait_urb()
that still allocates memory with GFP_NOIO.
The patch fixes usb_start_wait_urb() as well.

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.

On the Renesas R8A7791 SoC based boards there's MAX3355 USB OTG chip and mini-AB
USB connector corresponding to USB port 0 driven either by EHCI/OHCI or Renesas
USBHS gadget controller. And we'd like the host/gadget drivers to work based on
the cable type connected. An 'extcon' driver for MAX3355 has been written, so we
only need to bind to it via device tree which I'm doing in this patch.
(Perhaps, it would also make sense to use OTG HNP when the USBHS host mode is
active and a B-cable is connected but I don't have access to host-capable USBHS,
so wouldn't be able to test it.)

If usb bus is reset without a physical disconnection, all endpoints
will remain open. Call s3c_hsotg_disconnect() from reset handler to
report a disconnect to gadget framework. hsotg->connected is checked
in s3c_hsotg_disconnect() before processing disconnect.
In some cases, USBRst is seen before EnumDone and after it as well.
So move setting of hsotg->connected to set-address to avoid reporting
extra disconnection in this case.
