sfxge: remove unused common code EFSYS_OPT_RX_HDR_SPLIT
The EFSYS_OPT_RX_HDR_SPLIT optional feature in the common code
implemented the Lookahead Split feature of Windows. This split
received packets at a preconfigured byte offset, and delivered
the header and payload portions to separate receive queues.
Now the common code interface has no callers, so remove it.
Note that this should not be confused with the Header Data Split
feature of Windows, which splits packets at a header boundary.

sfxge: update NVRAM partition lookup for Medford
Prior to Medford, option ROM config was stored with one partition
per network port. Medford stores option ROM config in a single
partition (as an array of configurations, one per PF).
Update the EFXname /port to MCDI partition mapping for this.

sfxge: [EF10] support RxQ scattering control
If, for example, a VF is configured to use a 1500 byte MTU, but the port
it is attached to is set to 9000 bytes, overlength frames can be received
by the VF. As Huntington scatters by default, these overlength packets
would be scattered across several descriptors, with all except the last
having the CONT bit set.
To avoid this, disable scatter when creating RXQs if the firmware
supports doing so, which all recent versions do. Then we only get
a single descriptor from an overlength frame. This will have the CONT
bit set to indicate it was truncated, so we can discard it.

sfxge: retry VF vAdaptor allocation if it fails because of no EVB port yet
After an MC reboot, a VF driver may reset before the PF driver has
finished bringing everything back up. This includes the VFs EVB port.
MC_CMD_VADAPTOR_ALLOC is the first MCDI call after an MC reboot to
require the EVB port, so if it fails with MC_CMD_ERR_NO_EVB_PORT,
retry the command a few times after waiting a while.

sfxge: add prefast annotation to common code return types
Using a typedef for common code return types (rather than "int")
allows the Prefast static analyser to understand when a function
has been successful (and thus when its postconditions must hold).
This greatly reduces then number of false positives reported by
prefast for error paths in common code functions.

sfxge: modify nvram update functions for uio platform to support
RFID-selectable presets
Dynamic config partitions on boards that support RFID are divided into
a number of segments, each formatted like a partition, with header,
trailer and end tags. The first segment is the current active
configuration.
The segments are initialised by manftest and each contain a different
configuration e.g. firmware variant. The firmware can be instructed
via RFID to copy a segment over the first segment, hence changing the
active configuration. This allows ops to change the configuration of
a board prior to shipment using RFID.
Changes to the dynamic config may need to be written to all segments (in
particular firmware versions written by manftest) or just the first
segment (changes to the active configuration). See SF-111324-SW.
If only the first segment is written the code still needs to be aware of
the possible presence of subsequent segments as writing to a segment may
cause its size to increase, which would overwrite the subsequent
segments and invalidate them.
Boards that do not support RFID will only have one segment in their
dynamic config partition.
