aca5bc2002 sfxge(4): 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.

7a05b95510 sfxge(4): honour packed stream RSS restriction
Packed stream firmware variant on EF10 adapters has a
number of properties which must be taken into account:

 - Only one exclusive RSS context is available per port.
 - Only IP addresses can contribute to the hash value.

Huntington and Medford have one more limitation which
is important for the drivers capable of packed stream:

 - Hash algorithm is non-standard (i.e. non-Toeplitz).
   This implies XORing together source + destination
   IP addresses (or last four bytes in the case of IPv6)
   and using the result as the input to a Toeplitz hash.

This patch provides a number of improvements in order
to treat the mentioned limitations in the common code.

If the firmware variant is packed stream, the list of
supported hash tuples will include less variants, and
the maximum number of RSS contexts will be set to one.

will be possible to configure hashing by means of new definitions.

f1516f109b sfxge(4): distinguish filters for encapsulated packets
Add filter match flag to distinguish filters applied only to
encapsulated packets.

Match flags set should allow to determine whether a filter
is supported or not. The problem is that if specification
has supported set outer match flags and specified
encapsulation without any inner flags, check says that it
is supported, and filter insertion is performed. However,
there is no filtering of the encapsulated traffic. A new
flag is added to solve this problem and separate the
filters for the encapsulated packets.
