It is not safe to push TSO option descriptors if pacer bypass is
enabled, so to make sure that doesn't happen never push TSO option
descriptors.

The flag EFX_FILTER_MATCH_LOC_MAC_IG to represent filtering on the
individual/group bit of the MAC address (with the two cases being
distingusished by the MAC address in the filter specification) was
introduced to mirror the Linux driver filtering code, but the
implementations are different enough anyway that it isn't of much value.
Having separate flags for unknown unicast and multicast simplifies
the code and allows the set of flags to match those used by MCDI.
It will also makes it easier to report whether these filters are
supported.
In the MCDI definitions, the unknown multicast and unicast flags have
the values 0x40000000 and 0x80000000 respectively, and so using the
same values for simplicity requires 32 bits in the filter specification
to store the flags. This means the structure is now a little bigger
than 64 bytes, but filters are not often used on critical paths so this
shouldn't have much impact - on Linux they are also bigger than they
used to be.

The semantics of the MCDI interfacve require reading the first
dword of the header before any other data in the buffer. Add
a barrier to the common code MCDI handler to enforce this.

The port mask used for per-port sensors in mcdi_sensor_map
assumes zero-based port numbering. The port mask used in
the code is based on the one-based MCDI port number.
Fix this to lookup the correct per-port sensors, and to
allow reporting of sensor events from higher port numbers.

Both Siena and EF10 use the siena_ev_qpoll() implementation, but this
function is not defined in builds without EFSYS_OPT_SIENA.
Remove siena_ev_qpoll and inline it into efx_ev_qpoll to allow it
to be used in non-Siena builds.
Also remove outdated FIXME comment, as EF10 event batching/merging has
been implemented long ago without needing to modify this code.

padding setting is in the ADMIN group, and so fails for

For Siena and Huntington, the per-port bootcfg (aka expcfg) is

For Medford, the per-PF bootcfg is stored in a 2Kbyte sector
within a single shared partition. Update the common code to support
the new bootcfg layout.

Add SPI mode (PIO-only) support for Intel Synchronous Serial Port that
can be found in several Intel's products starting from PXA family.
Most of implementations have slight differences in behavior and in
addresses for registers subset. This driver covers only BayTrail SoC
implementation for it's the only hardware I have to test it on.
Driver attaches to ACPI bus only and does not have PCI or FDT support
for now due to lack of hardware to test it on.
"intelspi" is the best name I've managed to come up with. Linux driver
name (spi-pxa2xx) does not make sense because current implementation
does not support actual PXA2xx SoCs. And as far as I know there is no
codename assigned to Intel SSP chip.
