sys/cam/scsi/scsi_all.h:
In struct scsi_extended_inquiry_data:
- Increase the length field to 2 bytes, as it is 2 bytes in SPC-4.
- Add bit definitions for the various Activiate Microcode actions.
- Add the Sequential Access Logical Block Protection support bit,
since we need that in the sa(4) driver. (For modifications
that will come later.)
- Add definitions for the various Multi I_T Nexus Microcode
Download modes.
sys/cam/ctl/ctl.c:
As of SPC-4, a single report of "REPORTED LUNS DATA HAS CHANGED"
is to be given per I_T nexus. Once it is reported, the unit
attention condition should be cleared for all LUNS attached to
an I_T nexus.
Previously that only happened when a REPORT LUNS command was
processed.
This behavior may be different (according to SAM-5) when the
UA_INTLCK_CTRL bits are non-zero in the control mode page but
CTL does not currently support that.
So, in view of the spec, whenever we report a LUN inventory
change unit attention, clear it on all LUNs for that
particular I_T nexus.
Add a new function, ctl_clear_ua() that will clear a unit
attention on all LUNs for the given I_T nexus.
One field in the extended inquiry data that we could potentially
report at some point is the maximum supported sense data length.
To do that, we would the SIM to report (via path inquiry
perhaps) how much sense data it is able to send.
Add comments to explain some of the bits that are set in the
Extended Inquiry VPD page.
Add a few comments to make it more clear which functions handle
various VPD pages.

to leaving the TSC enabled as the timecounter and disabling C2+ instead
of disabling the TSC by default.

Add separate software Tx queue limit for non-TCP traffic to make total
limit higher and avoid local drops of TCP packets because of no
backpressure.
There is no point to make non-TCP limit high since without backpressure
UDP stream easily overflows any sensible limit.
Split early drops statistics since it is better to have separate counter
for each drop reason to make it unabmiguous.
Add software Tx queue high watermark. The information is very useful to
understand how big queues grow under traffic load.

Remove the first member alignment to cacheline since it is nop.
Use __aligned() for the whole structure to make sure that the structure
size is cacheline aligned.
Remove lock alignment to make the structure smaller and fit all members
used on event queue processing into one cacheline (128 bytes) on x86-64.
The lock is obtained as well from different context when event queue
statistics are retrived from sysctl context, but it is infrequent.
Reorder members to avoid padding and go in usage order on event
processing.
As the result all structure members used on event queue processing fit
into exactly one cacheline (128 byte) now.

In fact the pointer is used only if more than one TXQ is processed in
one interrupt.
It is used (read-write) on completion path only.
Also it makes the first part of the structure smaller and it fits now
into one 128byte cache line. So, TXQ structure becomes 128 bytes smaller.

string.
With this change it is not necessary redeclare the driver relations with
gpiobus and gpioc.
This also prevents redundant declarations when gpiobusvar.h is included
(which is going to happen soon).
It seems GAS makes the substitution automatically, but Clang's
integrated assembler does not (yet). It fails with "invalid operand for
instruction."
