<!-- 2005/10/08 -->
<li>Various <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=lge&sektion=4">lge(4)</a>
driver fixes, which turned it from a completely useless to a working driver,
now in GENERIC.
<li>In <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=tcpdump&sektion=8">tcpdump(8)</a>,
add a "best effort" MPLS decoder - since the protocol info is not always available
in the tag, a "guess" is done.
<li>In <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=vfs&sektion=9">vfs(9)</a>,
undo a very old change which was never quite finished, and could
cause severe corruption in the buffer lists by removing a buffer
from the hash twice.

a new parent.
<li>Sync to Intel's latest
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=em&sektion=4">em(4)</a>
driver, which adds support for the 82571 and 82572 PCI Express chips.

<li>In <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=iwi&sektion=4">iwi(4)</a>,
use firmware extended scan command (which doesn't crash) and enable
802.11a scanning for 2915ABG adapters.
<li>In ext2fs, use part of the reserved space on the disk inode to scatter
16 more bits for the UID/GID, making them 32-bit.
<li>Make <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=mg&sektion=1">mg(1)</a>

autonomous monitoring and recovery mechanism implemented directly in
platform management hardware and firmware.
<li>Bump max array size in
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ksh&sektion=1">ksh(1)</a>,
needed for MAKEDEV speed-ups.

ignore the "special" .#* files left over by cvs/emacs.
<li>In <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ami&sektion=4">ami(4)</a>,
