5037810f7e sfxge(4): add information if TSO workaround is required
In SF bug 61297 it's been confirmed that the hardware does not always
calculate the TCP checksum correctly with TSO sends.

The value of the Total Length field (IPv4) or Payload Length field
(IPv6) is the critical factor. We're sufficiently confident that if
these fields are zero then the checksum will be calculated correctly.

The information may be used by the drivers to check if the workaround is
required when FATSOv2 is implemented.

e919b7ec20 sfxge(4): generalise EF10 NVRAM buffer interface
The SFN driver's PartitionControl WMI object requires an API to parse
and filter partition data in TLV format, particularly for the Dynamic
Config partition. The ef10_nvram_buffer functions provide this
functionality but are tied to use with license partition only.
Modify functions so they are applicable to all TLV partitions and add
functions to support in-place tag modification.

4c7d5ddbe4 sfxge(4): remove probes when a Tx queue is too full
No need for probe messages when a TxQ is too full for a post to be done.

Existing drivers check if there is room in the queue before posting
descriptors, even though efx_tx_qdesc_post() does the check itself.

The new SFN Windows driver doesn't perform the check before calling
efx_tx_qdesc_post(), but that means these probes can get frequently
printed out. It's normal driver behaviour so there's no need to print
an error.

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

fcfb73b86d 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.
