2d91dd27a8 net/sfc/base: support the Rx event mode w/o continue
The recently added NO_CONT_EV mode is recommended for when looking for
maximum throughput on 100G links as it allows the firmware to operate
more efficiently. The biggest benefit is when using scatter and jumbo
frames, but it is also necessary to achieve line rate in other cases.

Support for NO_CONT_EV when scatter is disabled is simple - the main
datapath change is to always read the packet length from the prefix,
not the event. This requires storing a flag with the event queue so
the event handler knows NO_CONT_EV mode is in use.

Supporting NO_CONT_EV with scatter would require an API change.

(Now the ee_flags field in efx_evq_t is used on the datapath, move it
next to other fields which are also read on the datapath to try to avoid
reading an additional cache line.)

d6b55d5682 net/sfc/base: support different event descriptor sizes
For consistency with the size of Tx descriptors, the size of event
descriptors should be a part of NIC config, not a macro that is
common for all NIC families. Also, add a max number of EvQ buffers

802354e5a6 net/sfc/base: move EVQ descs number check to generic place
Now we have min/max limits in NIC config, so we can do check against
min/max in a generic place instead of NIC family specific functions.
Check that the descriptors number is a power of 2 is also can be
made common. It removes code duplication and makes NIC family
specific functions a bit shorter.

6f60cc4a78 net/sfc/base: support equal stride super-buffer Rx mode
Equal stride super-buffer Rx mode is supported by DPDK firmware
variant. One Rx descriptor provides many Rx buffers to firmware.
Rx buffers follow each other with specified stride.
Also it supports head of line blocking with timeout to address
drops when no Rx descriptors are available. So it gives extra time
to the driver to provide Rx descriptors before drop.

7e48cfe9ef net/sfc/base: update hardware headers for Medford2
The changes to efx_regs_ef10.h are auto-generated and include:

 - Updated event RX_L4_CLASS which is now 2 bits (was 3).
   The encoding of TCP, UDP and UNKNOWN are unchanged so
   the narrower Medford2 field definition is compatible with
   all controllers.

 - Fix definition of FATSOv2 option descriptors. These were
   added manually and differ from the auto-generated values
   in some fields (not yet used in common code). The field
   definitions have been corrected to agree with the Linux net
   driver headers and SF-108452-SW.

The remaining changes adapt the common code to use the updated
headers.

b9673329e1 net/sfc/base: support runtime VI window size
Medford2 uses a configurable VI window size, and requires
updates to register accesses to use a runtime VI window size
rather than the *_STEP register constants used for earlier
controllers.

Update the common code to query the VI window size via MCDI,
and add new EFX_BAR_VI_* accessor macros for per-VI registers.

The existing EFX_BAR_TBL_* macros can be used for non-VI
register tables (and for code that can never be called for
a Medford2 controller e.g. Siena-only code).

add a dedicated function to create packed stream RxQ without not
applicable paramters.
