Say it with me, "I will not chain commands with && in Makefiles"
This was originally fixed and explained quite well by bde@ in r36074. The
initial bmake integration caused 'set -e' to stop being used which lead to
r252419. Later 'set -e' expectations were fixed with bmake in r254980.
Because of the && here, errors would be ignored when building in parallel and
a dependency failed. Such as bootstrap-tools since it builds everything in
parallel. If any tool failed in obj/depend/all, it would just ignore the error
and continue to build. This later would result in cascaded errors that only
confused the real issue. This could also cause commands after the failed
command to still execute, leading to more confusion.
This should be fine if the command is in a sub-shell such as: (cmd1 && cmd2)
This reverts r252419.

After an MC reboot, a VF driver may reset before the PF driver has
finished bringing everything back up. This includes the VFs EVB port.
MC_CMD_VADAPTOR_ALLOC is the first MCDI call after an MC reboot to
require the EVB port, so if it fails with MC_CMD_ERR_NO_EVB_PORT,
retry the command a few times after waiting a while.

unwound through. For this we need the frame pointer (x29) to point to the
location on the stack where we stored the previous frame pointer, and link
register. To simplify this the stack pointer is only adjusted by addition
and subtraction, and not through the use of post increment on loads and
stores.
The updated frame layout is:
+------------+
| lr -- x30 |
+------------+
| fp -- x29 | <-- x29 points at this
+------------+
| Trap frame |
| ... |
| | <-- sp points at this
+------------+
The only difference is the first two items, and setting of x29.

In case when router has a lot of multicast groups, the reply can take
several packets due to MTU limitation.
Also we have a limit IGMP_MAX_RESPONSE_BURST == 4, that limits the number
of packets we send in one shot. Then we recalculate the timer value and
schedule the remaining packets for sending.
The problem is that when we call igmp_v3_dispatch_general_query() to send
remaining packets, we queue new reply in the same mbuf queue. And when
number of packets is bigger than IGMP_MAX_RESPONSE_BURST, we get endless
reply of IGMPv3 reports.
To fix this, add the check for remaining packets in the queue.

invalid (busy) page supposedly inserted by the vm_fault(), in the
OBSC_COLLAPSE_NOWAIT case. As a continuation to r221714, fix a case
when invalid page is found by the object scan in OBSC_COLLAPSE_WAIT
case as well. But, since this is waitable scan, we should wait for
the termination of the busy state and restart from the beginning of
the backing object' page queue. [*]
Do not free the shadow page swap space when the parent page is
invalid, otherwise this action potentially corrupts user data.
Combine all instances of the collapse scan sleep code fragments into
the new helper vm_object_backing_scan_wait().

This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so. A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR. These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package. The current implementation of targets/ is
very unmaintainable.
Currently rescue/rescue and sys/modules are still not connected.

- Support more of the toolchain from TOOLSDIR.
- This also improves 'make bootstrap-tools' to pass, for example,
AS=/usr/bin/as to Makefile.inc1, which will tell cross-tools to use
external toolchain support and avoid building things we won't be using
in the build.
- Always set the PATH to contain the staged TOOLSDIR directories when
not building the bootstrap targets.
The previous version was only setting this at MAKE.LEVEL==0 and if the
TOOLSDIR existed. Both of these prevented using staged tools that were
built during the build though as DIRDEPS with .host dependencies, such
as the fix for needing usr.bin/localedef.host in r291311.
This is not a common tool so we must build and use it during the build,
and need to be prepared to change PATH as soon as it appears.
This should also fix the issue of host dependencies disappearing from
Makefile.depend and then reappearing due to the start of the fresh build not
having the directory yet, resulting in the tools that were built not actually
being used.
- Only use LEGACY_TOOLS while building in Makefile.inc1. After r291317
and r291546 there is no need to add LEGACY_TOOLS into the PATH for
the pseudo/targets/toolchain build.
- Because the pseudo/targets/toolchain will now build its own
[clang-]tblgen, the special logic in clang.build.mk is no longer needed.
- LEGACY_TOOLS is no longer used outside of targets/pseudo/bootstrap-tools
so is no longer passed into the environment in its build.

staged.
None of usr.bin/clang/clang-tblgen or its dependencies need
lib/clang/include, so there is no cyclic dependency here to worry about.
The issue came about because of workarounds to dependencies on clang
being optional.
Without this, the clang-tblgen called during the build would change
after it was staged for the host. This would cause lib/clang/include to
rebuild due to changed build commands.

IPv4/IPv6 checksum offloading and VLAN tag insertion/stripping.
Since uether doesn't provide a way to announce driver specific offload

and will be done in the future.
Special thanks to Hayes Wang from RealTek who gave input.
This is mostly working around the converts/iconv port having '../ces/file.o'
in its OBJS list which resulted in '.depend../ces/file.o'. Now it will have
'.depend.._ces_file.o'.
Other implementations have :T which would result in '.depend.file.o' here, but
that could lead to collisions.

-MP creates empty targets for all dependency files, which can be useful when a
dependency is deleted from the file system. This would otherwise cause an
error for "don't know how to build FOO" since the .depend file is included
with the dependency registered.
This is mostly a workaround for the misc/dahdi-kmod port using '::' for one of
its dependencies, while -MP uses just ':'. This results in an 'Inconsistent
operator for' error.
