* Explain why 32768 entries is usually not enough
* Increase the scaling ratio to 10 to deal with 32-bit overflows that
can occur in calculating the canvas offsets
disk image. In some cases this can be a significant speed-up, if
most of the image can be kept in RAM while being populated.
On the 2GB image I'm currently working with, the build time,
excluding buildworld/buildkernel, goes from ~17 minutes to ~6
minutes.
This is not enabled by default, as it might have the opposite effect
on low-memory systems.
- During the generation of the image file be a bit more verbose in the
log file so it is possible to see what's being done.
- Add a NANO_DISKIMGDIR variable which makes it possibly to place the
final images somewhere other than ${MAKEOBJDIRPREFIX}. The default
value for NANO_DISKIMGDIR is $MAKEOBJDIRPREFIX.
Go for it: phk
Due to a typo, setting NANO_DATASIZE=-1 resulted in the data slice
being the same size as entire image instead of the size of the
remaining space on the image.
- Fix detection of overcommit of the slices.
This fix mainly result in a nicer error than when newfs etc. tries to
write beyond the end of the disk image.

default to the value of MK_KERBEROS unless set explicitly by
WITH_GSSAPI/WITHOUT_GSSAPI. (This introduces another type of
MK_* variables which itself is questionable.)
- Teach tools/build/options/makeman script that generates the
src.conf(5) manpage about the new type of MK_* variables.
- Fix broken logic in lib/Makefile.
WITHOUT_KERBEROS knob. While GSS can be used for other things
some third party software (most notably ports/x11/kdelibs3)
takes the presence of libgssapi as an indication that kerberos
is available, and attempts to link with the kerberos libs. If
they are not available, the build will fail.
Because you might want to use GSS but not kerberos, add a knob
to re-enable it if WITHOUT_KERBEROS is present.
Document the new knob, and the new behavior of WITHOUT_KERBEROS.

Convert compile time options to run time options [1].

o add things i want to TODO list
o add Record entry to each event which back-maps to the line # in the ktr file;
useful for finding local context when the ktr file has lots of items that
schedgraph doesn't grok
o add missing KTR_SCHED event handlers
o expose Counter max value through a ymax method for widget building
o show timestamps in records rejected 'cuz time goes backwards
Add regression tests for privileged and supposedly unprivileged
IP_IPSEC_POLICY,IPV6_IPSEC_POLICY setsockopt cases.
We may need to review the current 'good' results to make
sure they reflect what we really want.

Before that non-su users were able to open pfkey sockets as well.
Add a regression test so we can detect such problems in an automated way
in the future.
changes:
01 - Enhanced LRO:
LRO feature is extended to support multi-buffer mode. Previously,
Ethernet frames received in contiguous buffers were offloaded.
Now, frames received in multiple non-contiguous buffers can be
offloaded, as well. The driver now supports LRO for jumbo frames.
02 - Locks Optimization:
The driver code was re-organized to limit the use of locks.
Moreover, lock contention was reduced by replacing wait locks
with try locks.
03 - Code Optimization:
The driver code was re-factored to eliminate some memcpy
operations. Fast path loops were optimized.
04 - Tag Creations:
Physical Buffer Tags are now optimized based upon frame size.
For better performance, Physical Memory Maps are now re-used.
05 - Configuration:
Features such as TSO, LRO, and Interrupt Mode can be configured
either at load or at run time. Rx buffer mode (mode 1 or mode 2)
can be configured at load time through kenv.
06 - Driver Statistics:
Run time statistics are enhanced to provide better visibility
into the driver performance.
07 - Bug Fixes:
The driver contains fixes for the problems discovered and
reported since last submission.
08 - MSI support:
Added Message Signaled Interrupt feature which currently uses 1
message.
09 Removed feature:
Rx 3 buffer mode feature has been removed. Driver now supports 1,
2 and 5 buffer modes of which 2 and 5 buffer modes can be used
for header separation.
10 Compiler warning:
Fixed compiler warning when compiled for 32 bit system.
11 Copyright notice:
Source files are updated with the proper copyright notice.
