Previously ntb_transport(4) required at least 6 scratchpad registers,
plus 2 more for each additional memory window. That is too much for some
configurations, where several drivers have to share resources of the same
NTB hardware. This patch introduces new compact version of the protocol,
requiring only 3 scratchpad registers, plus one more for each additional
memory window. The optimization is based on fact that neither of version,
number of windows or number of queue pairs really need more then one byte
each, and window sizes of 4GB are not very useful now. The new protocol
is activated automatically when the configuration is low on scratchpad
registers, or it can be activated explicitly with loader tunable.

Address Lookup Table (A-LUT) being enabled allows to specify separate
translation for each 1/128th or 1/256th of the BAR2. Previously it was
used only to limit effective window size by blocking access through some
of A-LUT elements. This change allows A-LUT elements to also point
different memory locations, providing to upper layers several (up to 128)
independent memory windows. A-LUT hardware allows even more flexible
configurations than this, but NTB KPI have no way to manage that now.

This is the multiqueue receive code required for 9000-series chips.
Note that we still only configure a single RX queue for now. Multiqueue

For now iwm only ever uses queue 0 and the management queue, but my 9560
raises a software error interrupt during initialization if this flag is
not set. iwlwifi sets it for all 7000- and 8000-series hardware, so we

Match such chips using the device ID. We should really be checking the
subdevice as well, since a smaller number of 9460 and 9560 devices
actually belong to a new series of devices and require different
firmware, but that will require some extra logic in iwm_attach().

- amd_intr() does not account for the offset (0x200) in the counter
MSR address and ends up accessing invalid regions while reading
counter value after the 4th counter (0xC001000[8,9,..]) and
erroneously updates the counter values for counters [1-4].
- amd_intr() should only check core pmcs for interrupts since
other types of pmcs (L3,DF) cannot generate interrupts.
- fix pmc NMI's being ignored due to NMI latency on newer AMD processors
Note that this fixes a kernel panic due to GPFs accessing MSRs on
higher core count AMD cpus (seen on both Rome 7502P, and
Threadripper 2990WX 32-core CPUs)

- set flowid / hash type to M_HASHTYPE_NONE or M_HASHTYPE_OPAQUE_HASH

Some places in network code may need to verify that an ethernet address
is not the 'zero' address. Provide a standard macro ETHER_IS_ZERO for
this purpose, similar to the ETHER_IS_BROADCAST macro already available.
This patch also removes previous ETHER_IS_ZERO definitions in several
USB ethernet drivers, in favor of this centrally-located macro.

common execution path with polled mode.
Do not clear interrupts with reading of IG4_REG_CLR_INTR register as
interrupts, triggered during the period from reg_read(IG4_REG_INTR_STAT)
to reg_read(IG4_REG_CLR_INTR) will be missed.
Instead, read each IG4_REG_CLR_* register separately.
