How to force the HME card to work at 100mb (full-duplex).
If the auto negotiate does not work, then the 100-MB full-duplex mode
can be forced to run at 100-MB, Full-Duplex using the following:
Please try (if using /etc/rc2.d/S99...)
ndd -set /dev/hme instance 0
ndd -set /dev/hme adv_100T4_cap 0
ndd -set /dev/hme adv_100fdx_cap 1
ndd -set /dev/hme adv_100hdx_cap 0
ndd -set /dev/hme adv_10fdx_cap 0
ndd -set /dev/hme adv_10hdx_cap 0
ndd -set /dev/hme adv_autoneg_cap 0
or (if using /etc/system)
set hme:hme_adv_autoneg_cap=0
set hme:hme_adv_100T4_cap=0
set hme:hme_adv_100fdx_cap=1
set hme:hme_adv_100hdx_cap=0
set hme:hme_adv_10fdx_cap=0
set hme:hme_adv_10hdx_cap=0
Note that the order does make a difference.
The link is re-negotiated when the interface is
ifconfig'ed up or when ndd ndd adv_autoneg_cap command is executed.

uuidgen
UUIDGEN(1) User Commands UUIDGEN(1)
NAME
uuidgen - create a new UUID value
SYNOPSIS
uuidgen [options]
DESCRIPTION
The uuidgen program creates (and prints) a new universally unique identifier (UUID) using the libuuid(3) library. The new UUID can reason-
ably be considered unique among all UUIDs created on the local system, and among UUIDs created on other systems in the past and in the
future.
There are two types of UUIDs which uuidgen can generate: time-based UUIDs and random-based UUIDs. By default uuidgen will generate a ran-
dom-based UUID if a high-quality random number generator is present. Otherwise, it will choose a time-based UUID. It is possible to force
the generation of one of these two UUID types by using the -r or -t options.
OPTIONS
-r, --random
Generate a random-based UUID. This method creates a UUID consisting mostly of random bits. It requires that the operating system
have a high quality random number generator, such as /dev/random.
-t, --time
Generate a time-based UUID. This method creates a UUID based on the system clock plus the system's ethernet hardware address, if
present.
-h, --help
Display help text and exit.
-V, --version
Display version information and exit.
