Make logging of an ethernet address more consistent with
the rest of the kernel.
Miscellanea:
The %02hx use also did not quite match the u8 definition
of addr though that did not actually matter given normal
integer promotion rules.

Implement support for the XDP_REDIRECT action.
The redirected frame is transmitted and confirmed on the regular Tx/Tx
conf queues. Frame is marked with the "XDP" type in the software
annotation, since it requires special treatment.
We don't have good hardware support for TX batching, so the
XDP_XMIT_FLUSH flag doesn't make a difference for now; ndo_xdp_xmit
performs the actual Tx operation on the spot.

We write different metadata information in the software annotation

When macb device is suspended and system is powered down, the clocks
are removed and hence macb should be closed gracefully and restored
upon resume. This patch does the same by switching off the net device,
suspending phy and performing necessary cleanup of interrupts and BDs.
Upon resume, all these are reinitialized again.
Reset of macb device is done only when GEM is not a wake device.
Even when gem is a wake device, tx queues can be stopped and ptp device
can be closed (tsu clock will be disabled in pm_runtime_suspend) as
wake event detection has no dependency on this.

====================
mlx5-updates-2019-03-01
This series adds multipath offload support and contains some small updates
to mlx5 driver.
Multipath offload support from Roi Dayan:
We are going to track SW multipath route and related nexthops and reflect
that as port affinity to the HW.
1) Some patches are preparation.
2) add the multipath mode and fib events handling.
3) add support to handle offload failure for net error, i.e.
port down.
4) Small updates to match the behavior of multipath
Two small updates from Eran Ben Elisha,
5) Make a function static
6) Update PCIe supported devices list.

This patch adds calls in the stop() helper to ensure both MACs and
both PCS blocks are set in reset when the user manually sets a port
down. This is done so that we have the exact same block reset states at
boot time and when a port is set down.

This patch sets both the XPCS and MPCS blocks in reset when they aren't
used. This is done both at boot time and when reconfiguring a port mode.
The advantage now is that only the PCS used is set out of reset when the
port is configured (10GKR uses the MCPS while RXAUI uses the XPCS).

This patch makes sure both PPv2 MACs (GMAC + XLG MAC) are set in reset
while a port is reconfigured. This is done so that we make sure a MAC is
in a reset state when not used, as only one of the two will be set out
of reset after the port is configured properly.

This patch reworks the way the XLG MAC is set in reset: the XLG MAC is
set in reset at probe time and taken out of this state only when used.
The idea is to move forward a situation where only the blocks used are
taken out of reset. This also has the effect to handle the GMAC and the
XLG MAC in a similar way (the GMAC already is set in reset at boot
time).

This patch modifies the port_disable() helper to always disable both the
GMAC and the XLG MAC when called. At boot time we do not know of a port
was enabled in the firmware/bootloader, and if so what mode was used
(hence which of the two MACs was used).
This also help in implementing a logic where all blocks are disabled
when not used, and only enabled regarding the current mode used on a
given port.

The GMAC configuration helper modifies values in the auto-negotiation
register. Some of its values require the port to be forced down when
modifying their values. This patches fixes the check made on the bit to
be updated in this register, so that the port is forced down when
needed. This fix cases where some of those parameters were updated, but
not taken into account, such as when using RGMII interfaces.

The patch fixes the computation of RXQs being used by the PPv2 driver,
which is set depending on the PPv2 engine version and the queue mode
used. There are three cases:
- PPv2.1: 1 RXQ per CPU.
- PPV2.2 with MVPP2_QDIST_MULTI_MODE: 1 RXQ per CPU.
- PPv2.2 with MVPP2_QDIST_SINGLE_MODE: 1 RXQ is shared between the CPUs.
The PPv2 engine supports a maximum of 32 queues per port. This patch
adds a check so that we do not overstep this maximum.
It appeared the calculation was broken for PPv2.1 engines since
f8c6ba8424b0, as PPv2.1 ports ended up with a single RXQ while they
needed 4. This patch fixes it.
