address size that is different than the standard 6bits. This fixes
support for the Compaq NC3121 card, certain newer Intel Pro/100+
cards, and should also fix integrated NICs on SuperMicro and Compaq
motherboards.
The auto-sizing algorithm was taken from NetBSD (thanks!), which I
think got it from Linux originally.
Thanks also to Andrew Sparrow <spadger@best.com> and Joe Moore
<jomor@ahpcns.com> for supplying me with unworking Compaq and Intel
cards to develop and test the fixes with.
- Don't hard code 0x10000 as the entry point for the loader. Instead add
src/sys/boot/i386/Makefile.inc which defines a make variable with the
entry point for the loader. Move the loader's entry point up to
0x20000, which makes PXE happy.
- Don't try to use cpp to parse btxldr for the optional BTXLDR_VERBOSE,
instead use m4 to achieve this. Also, add a BTXLDR_VERBOSE knob in the
btxldr Makefile to turn this option on.
- Redo parts of cdldr's Makefile so that it now builds and installs cdboot
instead of having i386/loader/Makefile do that. Also, add in some more
variables to make the pxeldr Makefile almost identical and thus to ease
maintainability.
- Teach cdldr about the a.out format. Cdldr now parsers the a.out header
of the loader binary and relocates it based on that. The entry point of
the loader no longer has to be hardcoded into cdldr. Also, the boot
info table from mkisofs is no longer required to get a useful cdboot.
- Update the lsdev function for BIOS disks to parse other file systems
(such as DOS FAT) that we currently support. This is still buggy as
it assumes that a floppy with a DOS boot sector actually has a MBR and
parses it as such. I'll be fixing this in the future.
- The biggie: Add in support for booting off of PXE-enabled network
adapters. Currently, we use the TFTP API provided by the PXE BIOS.
Eventually we will switch to using the low-level NIC driver thus
allowing both TFTP and NFS to be used, but for now it's just TFTP.

reserve, in maximal NFS packets. Originally only 2 packets worth of
space was reserved. The default is now 4, which appears to greatly
improve performance for slow to mid-speed machines on gigabit networks.
Add documentation and correct some prior documentation.

fragmentation problem due to geteblk() reserving too much space for the
buffer and imposes a larger granularity (16K) on KVA reservations for
the buffer cache to avoid fragmentation issues. The buffer cache size
calculations have been redone to simplify them (fewer defines, better
comments, less chance of running out of KVA).
The geteblk() fix solves a performance problem that DG was able reproduce.
This patch does not completely fix the KVA fragmentation problems, but
it goes a long way

Fixed wrong path to libperl in LDADD in some funky objdir setups.

in LDADD so that `make checkdpadd' doesn't report non-errors.
