The license merging in r109471 didn't take into account that licensing
could change. Just removing the 3rd clause obviates the copyright
assignment to the NetBSD Foundation.
We do have plenty of files that have two or more licensing as in this
case, so fix this properly by splitting back the licenses as they are
upstream.

Part of this file originated in NetBSD, with the original file
carrying two versions of 4-clause BSD licenses. r109471 attempted to
simplify the situation by putting both licenses together.
Meanwhile, NetBSD dropped Clauses 3 and 4 from their own license, and
eventually NetBSD got permission from the University of Utah to drop the
3rd clause.
Keep the license "simple" by dropping the third clause since both TNF,
Utah/Berkeley and phk agree in principle that it can be dropped.

- Add some basic checks for i_fc* bits (ToDS, FromDS, MoreFrag, Protected);
those are used / checked across various places in Tx path.
- Mark injected 802.11 frame as encapsulated (just as it should be).
- Classify 802.11 frame in a proper way (extract ether_type from LLC header
for Data frames, use AC_BE queue for others (NoData / Management / Control).
- Subtract header length from tx_bytes statistics (so it will correspond
to the comment).

files that can use the default value.
It used to be required that the low-order bits of KERNVIRTADDR matched
the low-order bits of the physical load address for all arm platforms.
That hasn't been a requirement for armv6 platforms since FreeBSD 10.
There is no longer any relationship between load addr and KERNVIRTADDR
except that both must be aligned to a 2 MiB boundary.
This change makes the default KERNVIRTADDR value 0xc0000000, and removes the
options from all the platforms that can use the default value. The default
is now defined in vmparam.h, and that file is now included in a few new
places that reference KERNVIRTADDR, since it may not come in via the
forced-include of opt_global.h on the compile command line.
By default, or with the -P flag, find(1) should evaluate paths "physically."
For symlinks, this means using the link itself instead of the target.
Historically (since the import of BSD 4.4-lite from CSRG), find(1) has
failed to refer to the link itself, at least for -newer and -samefile.

is used as the bootloader on a number of PPC64 platforms. This involves the
following pieces:
- Making the first instruction a valid kernel entry point, since kexec
ignores the ELF entry value. This requires a separate section and linker
magic to prevent the linker from filling the beginning of the section
with stubs.
- Adding an entry point at 0x60 past the first instruction for systems
lacking firmware CPU shutdown support (notably PS3).
- Linker script changes to support the above.

This change mostly reverts r293436, which introduced the bug due to a belief
that geli(8) would allocate md(4) devices by itself. However, that belief is
incorrect. Instead of using linear probing to find available md(4) numbers,
it's best to use the existing attach_md function.

Fix for remainder overflow, when in rare cases adding remainder to divider
exceeded 1 and turned the total to 1000 in final formatting, taking up
the space for the unit character.
The fix continues the division of the original number if the above case
happens -- added the appropriate check to the for loop performing
the division. This lowers the value shown, to make it fit into the buffer
space provided (1.0M for 4+1 character buffer, as used by ls).
Add test case for the reported bug and extend test program to support
providing buffer length (ls -lh uses 5, tests hard-coded 4).

(now: Interrupt_Index[15]) and assigned the previously reserved bits
55:48 (Interrupt_Index[14:0] goes into 63:49 while Destination Field
used 63:56 and bit 48 now is Interrupt_Format) in the IO redirection
tables (see the VT-d specification, "5.1.5.1 I/OxAPIC Programming").
Thus, when not using interrupt remapping, ensure that all previously
reserved bits in the high part of the RTEs are zero instead of doing
a read-modify-write for their Destination Field bits only.
Otherwise, on machines based on Apollo Lake and its derivatives such
as Denverton, typically some of the previously preserved bits remain
set after boot when not employing interrupt remapping. The result is
that INTx interrupts are not getting delivered.
Note: With an AMD IOMMU, interrupt remapping apparently bypasses the
IO APIC altogether.
