# Think about root execution (change permisions file).

# P.e. ndd -set /dev/hme link_speed 1
# ndd -get /dev/hme link_status   0 = link up, 1 = link down
# ndd -get /dev/hme link_speed    0 = 10MBit,  1 = 100MBit
# ndd -get /dev/hme link_mode     0 = half duplex, 1 = full duplex
# ndd -get /dev/hme adv_autoneg_cap   0 = no autonegotiation, 1 = autoneg.

# lp_100T4_cap = 100BASE-T4

hme0:   OK.     100Mb.  Full Duplex.    LP autonegotiation.Autonegotiation.     

LP = link partner

Link partner capable of auto-negotation (lp_autoneg_cap 1)
speed and mode information is displayed when you use auto-negotiation
and get the link partner capabilities.
