296493-296496,296544,296710-296711,297863,299685: Catch up to changes to
the internal shared code.

Note that this merge includes two different firmware updates, but the
effective change is to update to the last version (1.15.37.0).  As such,
I've trimmed the log message of the first update (1.15.28.0).

In addition, the M_WAIT macro added in t4_regs.h had to be renamed to
CXGBE_M_WAIT to avoid a collision on 10.x that is not present on 11.

295778:
cxgbe: catch up with the latest hardware-related definitions.

296249:
cxgbe(4): Update T5 and T4 firmwares to 1.15.28.0.

296333:
cxgbe(4): First of many changes to reduce diffs with internal shared
code:

- Rename some CamelCase variables.
- s/t4_link_start/t4_link_l1cfg/g
- Pull in t4_get_port_type_description.
- Move t4_wait_op_done to t4_hw.c.
- Flip the order of the RDMA stats.
- Remove unsused function t4_iq_start_stop.
- Move t4_wait_op_done and t4_wait_op_done_val to t4_hw.c

296383:
cxgbe(4): Very basic T6 awareness.  This is part of ongoing work to
update to the latest internal shared code.

- Add a chip_params structure to keep track of hardware constants for
  all generations of Terminators handled by cxgbe.
- Update t4_hw_pci_read_cfg4 to work with T6.
- Update the hardware debug sysctls (hidden within dev.<tNnex>.<n>.misc.*) to
  work with T6.  Most of the changes are in the decoders for the CIM
  logic analyzer and the MPS TCAM.
- Acquire the regwin lock around indirect register accesses.

296471:
cxgbe(4): Updated register dumps.

- Get the list of registers to read during a regdump from the shared
  code instead of the OS specific code.  This follows a similar move
  internally.  The shared code includes the list for T6.

- Update cxgbetool to be able to decode T5 VF, T6, and T6 VF register
  dumps (and catch up with some updates to T4 and T5 register decode).

296478:
cxgbe(4): Add a struct sge_params to store per-adapter SGE parameters.
Move the code that reads all the parameters to t4_init_sge_params in the
shared code.  Use these per-adapter values instead of globals.

296481:
cxgbe(4): Overhaul the shared code that deals with the chip's TP block,
which is responsible for filtering and RSS.

Add the ability to use filters that match on PF/VF (aka "VNIC id") while
here.  This is mutually exclusive with filtering on outer VLAN tag with
Q-in-Q.

296485:
cxgbe(4): Update the interrupt handlers for hardware errors.

296488:
cxgbe(4): Updates to mailbox routines in the shared code.

296489:
cxgbe(4): Updates to the shared routines that deal with the serial EEPROM,
flash, and VPD.

296490:
cxgbe(4): Remove __devinit and SPEED_<foo> as part of catch up with
internal shared code.

296491:
cxgbe(4): Updates to shared routines that get/set various parameters via
the firmware.

296493:
cxgbe(4): Use t4_link_down_rc_str in shared code to decode the reason
the link is down, instead of doing it in OS specific code.

296494:
cxgbe(4): Many new functions in the shared code, unused at this time.

296495:
cxgbe(4): Fix t4_tp_get_rdma_stats.

296496:
cxgbe(4): Minor updates to the shared routines that deal with firmware images.

296544:
cxgbe(4): Reshuffle and rototill t4_hw.c, solely to reduce diffs with
the internal shared code.

296710:
cxgbe(4): Catch up with the latest list of card capabilities as reported
by the firmware.

296711:
cxgbe(4): Fix typo in previous commit.

297863:
Rename the 'M_B' macro in t4_regs.h to 'CXGBE_M_B'.

This fixes a conflict with the M_B macro in powerpc's
<machine/db_machdep.h> exposed by the recent addition of DDB commands
to the cxgbe driver.

299685:
cxgbe(4): Update T5 and T4 firmwares to 1.15.37.0.

These firmwares were obtained from the "Chelsio T5/T4 Unified Wire
v2.12.0.3 for Linux" release.  Changes since 1.14.4.0 (which is the
firmware in -STABLE branches) are in the "Release Notes" accompanying
the Unified Wire release and are copy-pasted here as well.
