The intention of this helper was to allow driver to specify one type
that it supports, so not only "any" value would pass. So make the API
more strict and allow driver to pass only 1 bit that is going
to be checked.

enetc: Support extended BD rings at runtime

First two patches are just misc code cleanup.
The 3rd patch prepares the Rx BD processing code to be extended
to processing both normal and extended BDs.
The last one adds extended Rx BD support for timestamping
without the need of a static config. Finally, the config option
FSL_ENETC_HW_TIMESTAMPING can be dropped.
Care was taken not to impact non-timestamping usecases.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Hardware timestamping support (PTP) on Rx requires extended
buffer descriptors, double the size of normal Rx descriptors.
On the current controller revision only the timestamping offload
requires extended Rx descriptors.
Since Rx timestamping can be turned on/off at runtime, make Rx ring
allocation configurable at runtime too. As a result, the static
config option FSL_ENETC_HW_TIMESTAMPING can be dropped and the
extended descriptors can be used only when Rx timestamping gets
activated.
The extension has the same size as the base descriptor, making
the descriptor iterators easy to update for the extended case.

When pktgen is used to measure the performance of dev_queue_xmit()
packet handling in the core, it is preferable to not hand down

Allow using pktgen on the loopback device, thus constraining

net: Add support for Synopsys DesignWare XPCS

This adds support for Synopsys DesignWare XPCS in net subsystem and
integrates it into stmmac.

At 1/8, we start by removing the limitation of stmmac selftests that needed
a PHY to pass all the tests.

Then at 2/8 we use some helpers in stmmac so that some code can be
simplified.

At 3/8, we fallback to dev_fwnode() so that PCI based setups wich may
not have CONFIG_OF can still use FW node.

At 4/8, we adapt stmmac to the new PHYLINK changes as suggested by Russell
King.

We proceed by doing changes in PHYLINK in order to support XPCS: At 5/8 we
add some missing speeds that USXGMII supports and at 6/8 we check if
Autoneg is supported after initial parameters are validated.

Support for XPCS is finally introduced at 7/8, along with the usage of it
in stmmac driver at 8/8.

Synopsys DesignWare XPCS is an MMD that can manage link status,

In this commit we add basic support for XPCS using USXGMII interface and
Clause 73 Auto-negotiation.

This is highly tied with PHYLINK and can't be used without it. A given
ethernet driver can use the provided callbacks to add the support for
XPCS.
