r355677:
Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
(RFC-8276) to the NFS client and server.
NFSv4.2 is comprised of several optional features that can be supported
in addition to NFSv4.1. This patch adds the following optional features:
- posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
- posix_fallocate()
- intra server file range copying via the copy_file_range(2) syscall
--> Avoiding data tranfer over the wire to/from the NFS client.
- lseek(SEEK_DATA/SEEK_HOLE)
- Extended attribute syscalls for "user" namespace attributes as defined
by RFC-8276.
For the client, NFSv4.2 is only used if the mount command line option
minorversion=2 is specified.
For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
and vfs.nfsd.server_max_minorversion4 have been added that allow
sysadmins to limit the minor versions of NFSv4 supported by the nfsd
server.
Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
on the server.

r354517:
iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
