dab8fe3207 net: do not inline netif_tx_lock()/netif_tx_unlock()
These are not fast path, there is no point in inlining them.

Also provide netif_freeze_queues()/netif_unfreeze_queues()
so that we can use them from dev_watchdog() in the following patch.

8160fb43d5 net: use an atomic_long_t for queue->trans_timeout
tx_timeout_show() assumed dev_watchdog() would stop all
the queues, to fetch queue->trans_timeout under protection
of the queue->_xmit_lock.

As we want to no longer disrupt transmits, we use an
atomic_long_t instead.

65483559dc net: ethernet: ti: cpsw: Enable PHY timestamping
If the used PHYs also support hardware timestamping, all configuration requests
should be forwared to the PHYs instead of being processed by the MAC driver
itself.

This enables PHY timestamping in combination with the cpsw driver.

Tested with an am335x based board with two DP83640 PHYs connected to the cpsw
switch.

There is a use case that the local and remote VTEPs are in the same

and the route dev is lo.

Actual tunnel interface can be created with a parameter "dev" [1],
which specifies the physical device to use for tunnel endpoint
communication. Pass this parameter to driver when looking up decap
route for offloads. So that a unicast route will be returned.

b9241f5413 net: document SMII and correct phylink's new validation mechanism
SMII has not been documented in the kernel, but information on this PHY
interface mode has been recently found. Document it, and correct the
recently introduced phylink handling for this interface mode.

r8169: disable detection of further chip versions that didn't make it to the mass market

There's no sign of life from further chip versions. Seems they didn't
make it to the mass market. Let's disable detection and if nobody
complains remove support a few kernel versions later.

It seems this chip version never made it to the wild. Therefore
disable detection and if nobody complains remove support completely
later.

4b5f82f6aa r8169: enable ASPM L1/L1.1 from RTL8168h
With newer chip versions ASPM-related issues seem to occur only if
L1.2 is enabled. I have a test system with RTL8168h that gives a
number of rx_missed errors when running iperf and L1.2 is enabled.
With L1.2 disabled (and L1 + L1.1 active) everything is fine.
See also [0]. Can't test this, but L1 + L1.1 being active should be
sufficient to reach higher package power saving states.

First two patches avoid holes in data section,
and last patch makes sure some siphash keys are contained
