Directory IO without a VM object will store data in 'malloced' buffers
severely limiting caching of the data. Without this change VM objects for
directories are only created on an open() of the directory.
TODO: Inline test if VM object already exists to avoid locking/function call
overhead.

- Adds some prepwork (Not all yet) for vimage in particular
support the delete the sctppcbinfo.xx structs. There is
still a leak in here if it were to be called plus we stil
need the regrouping (From Me and Michael Tuexen)
- Adds support for UDP tunneling. For BSD there is no
socket yet setup so its disabled, but major argument
changes are in here to emcompass the passing of the port
number (zero when you don't have a udp tunnel, the default
for BSD). Will add some hooks in UDP here shortly (discussed
with Robert) that will allow easy tunneling. (Mainly from
Peter Lei and Michael Tuexen with some BSD work from me :-D)

with most of system tools.
- Add -m and -g options to give output in megabytes and gigabytes
respectively.
- Bug in CA that does not get us incrementing the PBA properly which
made us more conservative.
- comment updated in sctp_input.c
- memsets added before we log

controller. L1 has several threshold/timer registers and they
seem to require careful tuned parameters to get best
performance. Datasheet for L1 is not available to open source
driver writers so age(4) focus on stability and correctness of
basic Tx/Rx operation. ATM the performance of age(4) is far from
optimal which in turn means there are mis-programmed registers or
incorrectly configured registers.
Currently age(4) supports all known hardware assistance including
- MSI support.
- TCP Segmentation Offload.
- Hardware VLAN tag insertion/stripping.
- TCP/UDP checksum offload.
- Interrupt moderation.
- Hardware statistics counter support.
- Jumbo frame support.
- WOL support.
L1 gigabit ethernet controller is mainly found on ASUS
motherboards. Note, it seems that there are other variants of
hardware as known as L2(Fast ethernet) and newer gigabit ethernet
(AR81xx) from Atheros. These are not supported by age(4) and
requires a seperate driver. Big thanks to all people who reported
feedback or tested patches.

It initialises using SYSINIT so that the SDT provider, probe and
