rounddown2 tends to produce longer lines than the original code
and when the code has a high indentation level it was not really
advantageous to do the replacement.
This tries to strike a balance between readability using the macros
and flexibility of having the expressions, so not everything is
converted.
The size of the reply can be different from the size of the command in
case a debug firmware asserts. fw_asrt() needs the entire reply in
order to decode the location of the assert.

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.

This provides a constant ABI and layout for these structures (especially
struct adapter) avoiding some foot shooting.

Figure out if the chip is counting PAUSE frames in the "normal" stats
and take them out if it is. This fixes a bug in the tx stats because
the default hardware behavior is different for Tx and Rx but the driver
was treating both the same way. The result was that OPACKETS, OBYTES,
and OMCASTS were under-reported (if tx_pause > 0) before this change.
Note that the mac_stats sysctl still gives you the raw value of these
statistics straight from the device registers.

This just adds a bunch of #ifdef TCP_OFFLOAD in the right places.

- Query the location of the log very early during attach. Refresh the
location later after establishing contact with the firmware.
- Save the log's location as a flat address in devlog_params.
- Use a memory window instead of backdoor access to the EDC/MC to read
the log.
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.

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.

- 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).

- 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

logic analyzer and the MPS TCAM.
- Acquire the regwin lock around indirect register accesses.

These firmwares were obtained from the beta "Chelsio T5/T4 Unified Wire
v2.12.0.2 for Linux" release. Changes since last release are listed in the
"Release Notes" accompanying the beta release and are copy-pasted here as well.
The plan is to have only GA'd firmwares in any -STABLE FreeBSD branch so I'll
MFC this (after 2 months) only if it ends up in a GA release.
