a8cb567afb Allow rc_conf_files to be redefined in rc.conf(5)
With this change, it's possible to redefine rc_conf_files (e.g.,
sysrc rc_conf_files+=/etc/rc.conf.other) and have the boot process
pick up settings in extra files. The sysrc(8) tool can be used to
query/enumerate/find/manage extra files configured in this manner.

5652770d8f Rename aiocblist to kaiocb and use consistent variable names.
Typically <foo>list is used for a structure that holds a list head in
FreeBSD, not for members of a list.  As such, rename 'struct aiocblist'
to 'struct kaiocb' (the kernel version of 'struct aiocb').

While here, use more consistent variable names for AIO control blocks:

- Use 'job' instead of 'aiocbe', 'cb', 'cbe', or 'iocb' for kernel job
  objects.
- Use 'jobn' instead of 'cbn' for use with TAILQ_FOREACH_SAFE().
- Use 'sjob' and 'sjobn' instead of 'scb' and 'scbn' for fsync jobs.
- Use 'ujob' instead of 'aiocbp', 'job', 'uaiocb', or 'uuaiocb' to hold
  a user pointer to a 'struct aiocb'.
- Use 'ujobp' instead of 'aiocbp' for a user pointer to a 'struct aiocb *'.

c80429cedb Update em(4) to 7.6.1; update igb(4) to 2.5.3.
Major changes:

- Add i219/i219(2) hardware support. (Found on Skylake generation and newer
  chipsets.)
  - Further to the last Skylake support diff, this one also includes support for
    the Lewisburg chipset (i219(3)).

- Add a workaround to an igb hardware errata.
  All 1G server products need to have IPv6 extension header parsing turned off.
  This should be listed in the specification updates for current 1G server
  products, e.g. for i350 it's errata #37 in this document:
  http://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/ethernet-controller-i350-spec-update.pdf

- Avoton (i354) PHY errata workaround added

And a bunch of minor fixes, as well as #defines for things that the current
em(4)/igb(4) drivers don't implement.

89b50f6b4d Fix EFI multi device boot support
Fix EFI boot support when presented with multiple valid boot partitions
across multiple devices.

It now prefers to boot from partitions that are present on the underlying
device that the boot1 image was loaded from. This means that it will boot
from the partitions on device the user chose from EFI boot menu in
preference to those on other devices.

Also fixed is the recovery from a failed attempt to boot, from a seemingly
valid partition, by continuing to trying all other available partitions
no matter what the error.

boot1 now use * to signify a partition what was accepted from the preferred
device and + otherwise.

Finally some error messages where improved and DPRINTF's with slowed boot
to aid debugging.

ZFS will still be preferred over UFS when both are available on the boot
device.

74506a55d6 hyperv/hn: Reorganize TX csum offloading
- For non-TSO offloading, we don't need to access mbuf to know
  which csum offloading is requested, we can just use the
  CSUM_{IP,TCP,UDP} in the csum_flags.
- For TSO offloading, we still can depend on CSUM_{TSO4,TSO6}
  in the csum_flags to tell whether the TSO packet is an IPv4
  TSO packet or an IPv6 TSO packet.

This streamlines csum offloading handling (remove the two goto)
and allows us the nuke the unnecessary get_transport_proto_type().

af582aaed1 When matching brand to the ELF binary by notes, try to find a brand
with interpreter name exactly matching one wanted by the binary.  If
no such brand exists, return first brand which accepted the binary by
note.

The change fixes a regression after r292749, where e.g. our two ia32
compat brands, ia32_brand_info and ia32_brand_oinfo, only differ by
the interpeter path and binary matches to a brand by linkage order.
Then old binaries which require /usr/libexec/ld-elf.so.1 but matched
against ia32_brand_info with interp_path /libexec/ld-elf.so.1, were
considered requiring non-standard interpreter name, and magic to force
ld-elf32.so.1 did not happen.

Note that it might make sense to apply the same selection of brands
for other matching criteria, SCO EI_OSABI and 3.x string.
