d429005fdf cxgb4/cxgb4vf: Add support for SGE doorbell queue timer
T6 introduced a Timer Mechanism in SGE called the
SGE Doorbell Queue Timer. With this we can now configure
TX Queues to get CIDX Updates when:

    Time(CIDX == PIDX) >= Timer

Previously we rely on TX Queue Status Page updates by hardware
for DMA completions. This will make Hardware/Firmware actually
deliver the CIDX Updates as Ingress Queue messages with
commensurate Interrupts.

So we now have a new RX Path component for processing CIDX Updates
and reclaiming TX Descriptors faster.

1d19023fa6 cxgb4: change the port capability bits definition
MDI Port Capabilities bit definitions were inconsistent with
regard to the MDI enum values. 2 bits used to define MDI in
the port capabilities are not really separable, it's a 2-bit
field with 4 different values. Change the port capability bit
definitions to be "AUTO" and "STRAIGHT" in order to get them
to line up with the enum's.

This commit does the following:

  on this size.
- Also contains changes to get HMA memory information via debugfs.

49b53a93a6 iw_cxgb4: add fast-path for small REG_MR operations
When processing a REG_MR work request, if fw supports the
FW_RI_NSMR_TPTE_WR work request, and if the page list for this
registration is <= 2 pages, and the current state of the mr is INVALID,
then use FW_RI_NSMR_TPTE_WR to pass down a fully populated TPTE for FW
to write.  This avoids FW having to do an async read of the TPTE blocking
the SQ until the read completes.

To know if the current MR state is INVALID or not, iw_cxgb4 must track the
state of each fastreg MR.  The c4iw_mr struct state is updated as REG_MR
and LOCAL_INV WRs are posted and completed, when a reg_mr is destroyed,
and when RECV completions are processed that include a local invalidation.

This optimization increases small IO IOPS for both iSER and NVMF.

9b86a8d19b cxgb4/cxgb4vf: Allocate more queues for 25G and 100G adapter
We were missing check for 25G and 100G while checking port speed,
which lead to less number of queues getting allocated for 25G & 100G
adapters and leading to low throughput. Adding the missing check for
both NIC and vNIC driver.

Also fixes port advertisement for 25G and 100G in ethtool output.
