This change is about moving the -f documentation into the right place in
the manual. Also, document the IFCONFIG_FORMAT variable in the
ENVIRONMENT section.

In order to clean up the layout of the manual page, let's keep

change any content, it's meant to only move the content around before
refactoring.

If the pfctl_add_eth_rule() ioctl fails return the errno, not the error
returned by ioctl(). That will give us slightly more insight into what
went wrong, because ioctl() would always return -1.

In vmbus_pcib_prepopulate_bars(), after writing all 1's to the
avialable device bars, those without being configured by device driver
are also set to its initialized values. However, this could cause
weird problem which results to device failure. The issue has been
reported to happen on LSI 9211-8i HBA card for DDA access on Hyper-V.
Writing back the orignal BAR values seem to work around this problem.

fstyp looks for a 0x55 0xAA signature at offset 510, but this is not
required by specifications and is not proivded by the Raspberry Pi Nano
bootloader.
We should really remove the signature check and implement a more
comprehensive BPB validation instead, but it will require more
investigation and testing. For now just add a special case for the
Raspberry Pi Nano bootloader, to avoid introducing regressions or new
false positives.

32-bit architectures other than i386 have 64-bit time_t which results
in a struct timespec with 12 bytes for tv_sec and tv_nsec, and 4 bytes
of padding. Zero the padding holes in struct stat32 and struct
freebsd11_stat32.
i386 has 32-bit time_t; struct timespec is 8 bytes and has no padding.
Found by inspection, prompted by a report by Reno Robert of Trend Micro
Zero Day Initiative. The originally reported issue (ZDI-CAN-14538) is
already fixed in all supported FreeBSD versions (it was addressed
incidentally as part of the 64-bit inode project).

- There is no need to mention in the synopsis that -f can be a list of
comma-separated type:format pairs. Let's keep it simple instead.
- Mention that -f can be supplied multiple times.
- Add -f to other entries in the synopsis where it can be used.

We document capability codes (the CAPS field of "ifconfig wlan0 scan")
in both ifconfig(8) and the handbook. The list is more complete in the
manual page, while the descriptions of individual capabilities are more
detailed in the handbook.
In order to reduce content duplication and bit rot, let's move
handbook's details to the manual page and reference the manual page
whenever necessary.

*_CFG_PAGE ioctl handlers in the mpr, mps, and mpt drivers allocated a
buffer of a caller-specified size, but copied to it a fixed size header.
Add checks that the size is at least the required minimum.
Note that the device nodes are owned by root:operator with 0640
permissions so the ioctls are not available to unprivileged users.
This change includes suggestions from scottl, markj and mav.
Two of the mpt cases were reported by Lucas Leong (@_wmliang_) of
Trend Micro Zero Day Initiative; scottl reported the third case in mpt.
Same issue found in mpr and mps after discussion with imp.

Commit 867c27c23a modified the NFS client so that
it did IO_APPEND writes directly to the NFS server
bypassing the buffer cache, via a call to
nfs_directio_write(). Unfortunately, this (very old)
function assumed that the uio iov was for user space
addresses. As such, a IO_APPEND VOP_WRITE() that
was for system space, such as ktrace(1) does, would
write bogus data.
This patch fixes nfs_directio_write() so that it
handles kernel space uio iovs.
