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: David 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.

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.

Once the call to qdio_establish() has completed, qdio is free to deliver
data IRQs to the device driver's IRQ poll handler.
For qeth (the only qdio driver that currently uses IRQ polling) this is
problematic, since the IRQs can arrive before its NAPI instance is
even registered. Calling napi_schedule() from qeth_qdio_start_poll()
then crashes in various nasty ways.
Until recently qeth checked for IFF_UP to drop such early interrupts,
but that's fragile as well since it doesn't enforce any ordering.
Fix this properly by bringing up the qdio device in IRQS_DISABLED mode,
and have the driver explicitly opt-in to receive data IRQs.
qeth does so from qeth_open(), which kick-starts a NAPI poll and then
calls qdio_start_irq() from qeth_poll().
Also add a matching qdio_stop_irq() in qeth_stop() to switch the qdio
dataplane back into a disabled state.
