Add basic ndo_xdp support to setup and query program, configure the NIC
to run in rx page mode, and support XDP_PASS, XDP_DROP, XDP_ABORTED
actions only.
v3: Pass modified offset and length to stack for XDP_PASS.
Remove Kconfig option.
v2: Added trace_xdp_exception()
Added dma_syncs.
Add logic for an extra set of TX rings for XDP. If enabled, this
set of TX rings equals the number of RX rings and shares the same
IRQ as the RX ring set. A new field bp->tx_nr_rings_xdp is added
to keep track of these TX XDP rings. Adjust all other relevant functions
to handle bp->tx_nr_rings_x
In the current code, we have separate rx_event and agg_event parameters
to keep track of rx and aggregation events. Combine these events into
an u8 event mask with different bits defined for different events. This
way, it is easier to expand the logic to include XDP tx events.

The first 10 patches refactor the code (rx/tx code paths and ring logic)
and add the basic infrastructure to support XDP. The 11th patch adds
basic ndo_xdp to support XDP_DROP and XDP_PASS only. The 12th patch
completes the series with XDP_TX.

To support setting the pause parameters, the driver can no longer just
mirror the PHY. The set_pauseparam feature allows the driver to
force the setting in the MAC, regardless of how the PHY is configured.
This means that we now need to maintain an internal state for pause

A
Since commit 364b6055738b ("net: busy-poll: return busypolling status
to drivers"), napi_complete_done() returns a boolean that can be used
by drivers to conditionally rearm interrupts.
Testing with a 7142 shows a small latency improvement of ~100 ns.

When PSAMPLE is a loadable module, spectrum must not be built-in:
drivers/net/built-in.o: In function `mlxsw_sp_rx_listener_sample_func':
spectrum.c:(.text+0xe357e): undefined reference to `psample_sample_packet'
This adds a Kconfig dependency to enforce usable configurations.
