At work we have a single tftp server that provides installation data for
a variety of operating systems. I'd rather place our FreeBSD-related
files in a subdirectory, instead of the root.
It would be nice if this setting could be run-time configurable, but at
least in our specific case, this is not possible, as pxeboot is
chainloaded through pxelinux.

- Add read-only sysctls for all of the tunables supported by the igb and
em drivers.
- Make the per-instance 'enable_aim' sysctl truly per-instance by having it
change a per-instance variable (which is used to control AIM) rather
than having all of the per-instance sysctls operate on a single global
variable.
While here, restore the previously existing hw.igb.rx_processing_limit
tunable as it is very useful to be able to set a default tunable that
applies to all adapters in the system.

At work, where we use use KVM+QEMU, we notice that pxeboot is pratically
impossible because of network timeouts. This is due to the fact that the
RTC code makes aggressive jumps.
Two RTC reads does not seem to be sufficient. Change the code to check
for 8 identical RTC values.

there are some places in the kernel where fixing them is too disruptive,
or where there is a false positive.
In this case, disable -Wconstant-conversion for two aic7xxx-related
files, as they get the following warning on i386 (and possibly on other
32-bit arches):
sys/dev/aic7xxx/ahc_pci.c:112:10: warning: implicit conversion from 'long long' to 'bus_addr_t' (aka 'unsigned int') changes value from 549755813887 to 4294967295 [-Wconstant-conversion]
? 0x7FFFFFFFFFLL
~~^~~~~~~~~~~~~~
This is a false positive, since the code only passes the 0x7FFFFFFFFFLL
argument, if sizeof(bus_addr_t) is larger than 4 (e.g. on 64 bit arches,
or when PAE is enabled on i386). The code could be refactored to do
compile-time checks, but that is more disruptive.

In the future we may want to perform the switch even if the console is
currently in the graphics mode by trying to reset the video adapter first
(e.g. by executing vesa/vga bios post). That would probably require
some sort of a one-way flag as returning the control of the console back
to the interrupted application most likely would result in a mess.

This change is designed to let USB keyboard work in the panic context
with stop_scheduler_on_panic=1. Most of change consists of removing
mtx_owned() checks where they can be easily avoided. Some additional
lock cleanup is performed along the way.
A list of the smaller changes:
- newbus methods should be executed with Giant already held, just assert
this
- kbd methods called in the non-polling context should be executed with
Giant already held, just assert this
- Giant is recursive, so we should just take it where we must have it,
without redundant checks if we already have it
- thanks to recent syscons changes we don't need to go through the hoops
to detect if kernel is going to poll us; polling mode is now clearly
separated from non-polling mode
- at present the polling mode can be entered by only one thread
- document special cases in greater detail
Please note that the ukbd code and underlying USB code still lve
dangerously in the kdb context by trying to obtain various locks
including the Giant. If any of those locks are already held by the
stopped threads, then the things would blow up.
Another limitation of the ukbd driver is that it is detached before a
system enters the halt state.
With this commit we can enable kern.stop_scheduler_on_panic by default,
that should not introduce any regressions.

When SCHEDULER_STOPPED() is true the mtx_owned() call may return
an unexpected and thus meaningless result.
So, in the code paths that can be reached when SCHEDULER_STOPPED() is true
we need to protect the mtx_owned() calls with the SCHEDULER_STOPPED()
checks and ensure that an appropriate branch is taken in each case.

get a reply of EEXIST from an NFS server when a Mkdir RPC was retried,
for an NFS over UDP mount.
Upon investigation, it was found that the client was retransmitting
the Mkdir RPC request over UDP, but with a different xid. As such,
the retransmitted message would miss the Duplicate Request Cache
in the server, causing it to reply EEXIST. The kernel client side
UDP rpc code has two timers. The first one causes a retransmit using
the same xid and socket and was set to a fixed value of 3seconds.
(The default can be overridden via CLSET_RETRY_TIMEOUT.)
The second one creates a new socket and xid and should be larger
than the first. However, both NFS clients were setting the second
timer to nm_timeo ("timeout=<value>" mount argument), which defaulted to
1second, so the first timer would never time out.
This patch fixes both NFS clients so that they set the first timer
using nm_timeo and makes the second timer larger than the first one.
