It is better do not mix TxQ creation and receive event flags since only
checksum flags are applicable to TxQ.
Also it will allow to add a new TxQ creation specific flags.

The SFL9122 "Huntington" controller was never built.

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.

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.

To delay packets from a particular TX queue by a particular time, write a value
into the TX Pace table s.t. pace time <= TX Pace Clock Period * (2 ^ pace value)
- the TX pace clock is 1/13 of the system clock, so its period should be 104 or
52 ns depending on whether turbo mode is active.
EFX_TX_PACE_CLOCK_BASE added by me.

Before the common code had hard coded limits on the IDs RXQs and TXQs could
be created with which were suited for the Windows driver with VMQ, and so
would prevent queues with IDs greater than or equal to 259 (for TXQs) or 768
(for RXQs) from being created. This change allows the limits to be set in
efsys.h, so that all 1024 queues can be created during new manftest tests.
Also, the descriptor cache sizes were also hard coded to values suited to
the smaller queue counts, and so it was necessary to make them configurable
as well.

this set of patches fixes support for systems with > 32 cores.
Details include
sfxge: RXQ index (not label) comes from FW in flush done/failed events
Change the second argument name of the efx_rxq_flush_done_ev_t and
efx_rxq_flush_failed_ev_t prototypes to highlight that RXQ index (not label)
comes from FW in flush done and failed events.
sfxge: TXQ index (not label) comes from FW in flush done event
Change the second argument name of the efx_txq_flush_done_ev_t prototype to
highlight that TXQ index (not label) comes from FW in flush done event.
sfxge: use TXQ type as label to support more than 32 TXQs
There are 3 TXQs in event queue 0 and 1 TXQ (with TCP/UDP checksum offload)
in all other event queues.

based on Solarflare SFC9000 family controllers. The driver supports jumbo
frames, transmit/receive checksum offload, TCP Segmentation Offload (TSO),
Large Receive Offload (LRO), VLAN checksum offload, VLAN TSO, and Receive Side
Scaling (RSS) using MSI-X interrupts.
