bhyve sometimes segfaults when using an e1000 NIC with a Windows guest.
We are only updating our tdba and cached host mapping when the low address
register is written and when tx is set enabled, but not when the high address
or length registers are written. It is observed that Windows 10 is occasionally
enabling tx first then writing the registers in the order low, high, len. This
leaves us with a bogus base address and mapping, which causes a segfault later
when we try to copy from a descriptor that has unpredictable garbage in a
pointer.
Updating the address and mapping when any of those registers change seems to fix
that particular issue.

The NVMe emulation code did not explicitly initialize queue head and
tail pointers on queue creation. As these pointers are part of
calloc()'ed memory, this only becomes a problem if the queues are
deleted and then recreated.
This error can manifest with messages about completions not matching a
command.
Some operating systems believe bhyve's emulated NVMe drive is failing
based on certain values in the SMART / Health Information log page being
zero. Fix is to set the reported temperature and available spare values
to reasonable defaults.

This fixes a coredump with NetBSD guests when XHCI is configured.
On seeing the AC64 flag clear, the NetBSD XHCI driver was only writing
to the lower 32-bits of 64-bit physical address registers. The emulation
relies on a write to the hi 32-bits to calculate a host virtual address
for internal use, and has always supported 64-bit addressing.
All other guests were seen to write to both the lo- and hi- address
registers, regardless of the AC64 setting.

SMART data in NVMe includes statistics for number of read and write
commands issued as well as the number of "data units" read and written.
NVMe defines "data unit" as thousands of 512 byte blocks (e.g. 1 data
unit is 1-1,000 512 byte blocks, 3 data units are 2,001-3,000 512 byte
blocks).

- Data Units Read
- Data Units Written
- Host Read Commands
- Host Write Commands
