Add tx_ring_size, and rx_ring_size variables to macb object, which

A BPF program is required to check the return register of a
map_elem_lookup() call before accessing memory. The verifier keeps
track of this by converting the type of the result register from
PTR_TO_MAP_VALUE_OR_NULL to PTR_TO_MAP_VALUE after a conditional
jump ensures safety. This check is currently exclusively performed
for the result register 0.

In the event the compiler reorders instructions, BPF_MOV64_REG
instructions may be moved before the conditional jump which causes
them to keep their type PTR_TO_MAP_VALUE_OR_NULL to which the
verifier objects when the register is accessed:

0: (b7) r1 = 10
1: (7b) *(u64 *)(r10 -8) = r1
2: (bf) r2 = r10
3: (07) r2 += -8
4: (18) r1 = 0x59c00000
6: (85) call 1
7: (bf) r4 = r0
8: (15) if r0 == 0x0 goto pc+1
 R0=map_value(ks=8,vs=8) R4=map_value_or_null(ks=8,vs=8) R10=fp
9: (7a) *(u64 *)(r4 +0) = 0
R4 invalid mem access 'map_value_or_null'

This commit extends the verifier to keep track of all identical
PTR_TO_MAP_VALUE_OR_NULL registers after a map_elem_lookup() by
assigning them an ID and then marking them all when the conditional
jump is observed.

support smc91x on mainstone and devicetree

This series aims at bringing support to mainstone board on a
device-tree based build, as what is already in place for legacy
mainstone.

The bulk of the mainstone "specific" behavior is that a u16 write
doesn't work on a address of the form 4*n + 2, while it works on 4*n.

The legacy workaround was in SMC_outw(), with calls to
machine_is_mainstone(). These calls don't work with a pxa27x-dt
machine type, which is used when a generic device-tree pxa27x machine
is used to boot the mainstone board.

Therefore, this series enables the smc91c111 adapter of the mainstone
board to work on a device-tree build, exaclty as it's been working for
years with the legacy arch/arm/mach-pxa/mainstone.c definition.

As a sum up, this extends an existing mechanism to device-tree based
pxa platforms.

Add support for led triggers on phy link state change

Fix skge driver that declared enum contants that conflicted with enum
constants in linux/leds.h

Create function that encapsulates actions taken during the adjust phy link step
of phy state changes.

Create function that provides list of speeds currently supported by the phy.

Add support for led triggers on phy link state changes by adding
a config option. When set the config option will create a set of led triggers
for each phy device. Users can use the led triggers to represent link state
changes on the phy.

v2:
 * New patch that creates phy_adjust_link function to encapsulate actions taken
   when adjusting phy link during phy state changes
 * led trigger speed strings changed to match existing phy speed strings
 * New function that maps speeds to led triggers
 * Replace magic constants with definitions when declaring trigger name
   buffer and number of triggers.
v3:
 * Changed LED_ON to LED_REG_ON in skge driver to avoid possible future
   conflict and improve consistency.
 * Dropped rtl8712 patch that was accepted separately.
v4:
 * tweaked commit message
v5
 * Changed commit message to explain relationship between the new triggers and
   leds driven by phys.
 * Added new patch that creates phy_supported_speeds function.
 * Moved phy_leds_triggers_register and phy_leds_triggers_unregister to
   phy_attach and phy_detach respectively. This change is so the
   phydev->supported field will be filled by the time the triggers are
   registered.
 * Changed hardcoded list of triggers to dynamic list determined by speeds
   return by phy_supported_speeds.

Create an option CONFIG_LED_TRIGGER_PHY (default n), which will create a
set of led triggers for each instantiated PHY device. There is one LED
trigger per link-speed, per-phy.
The triggers are registered during phy_attach and unregistered during
phy_detach.

This allows for a user to configure their system to allow a set of LEDs
not controlled by the phy to represent link state changes on the phy.
LEDS controlled by the phy are unaffected.

For example, we have a board where some of the leds in the
RJ45 socket are controlled by the phy, but others are not. Using the
triggers provided by this patch the leds not controlled by the phy can
be configured to show the current speed of the ethernet connection. The

    ip link add bond1 type bond
    ip link set bond1 up
    ip link set eth3 down
    ip link set eth3 master bond1
    ip link set eth3 up

    ip link add bridge type bridge

    ip link set macvlan up

    ip link add myvrf type vrf table 1234

    ip link set bridge master myvrf

Case 1 enslave macvlan to the vrf before enslaving the bond to the bridge:

    ip link set macvlan master myvrf
    ip link set bond1 master bridge

Attempts to delete the VRF:
    ip link delete myvrf

When the BUG is converted to a WARN_ON it shows 4 missing adjacencies:
  eth3 - myvrf, mvrf - eth3, bond1 - myvrf and myvrf - bond1

All of those are because the __netdev_upper_dev_link function does not
properly link macvlan lower devices to myvrf when it is enslaved.

The second case just flips the ordering of the enslavements:
    ip link set bond1 master bridge
    ip link set macvlan master myvrf

Then run:
    ip link delete bond1
    ip link delete myvrf

The vrf delete command hangs because myvrf has a reference that has not
been released. In this case the removal code does not account for 2 paths
between eth3 and myvrf - one from bridge to vrf and the other through the
macvlan.

Rather than try to maintain a linked list of all upper and lower devices
per netdevice, only track the direct neighbors. The remaining stack can
be determined by recursively walking the neighbors.

The existing netdev_for_each_all_upper_dev_rcu,
netdev_for_each_all_lower_dev and netdev_for_each_all_lower_dev_rcu macros
are replaced with APIs that walk the upper and lower device lists. The
new APIs take a callback function and a data arg that is passed to the
callback for each device in the list. Drivers using the old macros are
converted in separate patches to make it easier on reviewers. It is an
API conversion only; no functional change is intended.

v3

Now that the network stack core min/max MTU checking infrastructure is in

For the most part, every patch does the same essential thing: removes the

ranges into the core net_device min_mtu and max_mtu fields, and where
possible, removes ndo_change_mtu functions entirely.
