How do I find the speed my network card is at?
      
           a. /usr/sbin/ndd -set /dev/hme instance 0
               1. instance 0 - hme0
               2. instance 1 - hme1
           b. /usr/sbin/ndd -get /dev/hme transciever_inuse
               1. 0 - onboard
               2. 1 - offboard card (mii)
           c. /usr/sbin/ndd -get /dev/hme link_status
               1. 0 - down
               2. 1 - up
           d. /usr/sbin/ndd -get /dev/hme link_speed
               1. 0 - 10Mb
               2. 1 - 100Mb
           e. /usr/sbin/ndd -get /dev/hme link_mode
               1. 0 - half duplex
               2. 1 - full duplex
      
       2. How do I configure what my network card is capable of?
      
           a. Method 1
               1. /etc/system
                   a. this sets global defaults for the driver, therefore
                      it is effective for all instances of the card
                   b. HME/QFE/GE interfaces
                       1. set hme:hme_adv_autoneg_cap=0

                   c. QE/LE interfaces
                       1. these 10mbit interfaces dont support full duplex
                          operation
           b. Method 2
               1. This method allows more granular control over the interface
                  driver.  You can specify configuration by port.
               2. /usr/sbin/ndd -set /dev/hme instance 0

                   3. 1 - on
      
       3. How do I configure what my link partner is capable of?
      
           a. /usr/sbin/ndd -set /dev/hme instance 0
               1. instance 0 - hme0
               2. instance 1 - hme1
           b. /usr/sbin/ndd -get /dev/hme lp_autoneg_cap

       4. How can I tell if my card is active on the network?

           a. Method 1 (Openboot PROM)
               1. watch-net

       5. How do I use multiple ethernet interfaces on the same network segment?

           a. Method 1 (modern cards, 1997+)
               1. Modern Sun Adapters have unique mac addresses encoded in the FCode Prom.
               2. /usr/sbin/eeprom local-mac-address?=true

           b. Method 2 (older cards)
               1. From InfoDoc 16733; "Section 3.2.3(4) of the IEEE 802.3 spec
                  defines a reserved bit in the Ethernet Address that can be
                  used to administer a universally assigned ethernet
                  addresses. A Locally administered address (LAA) can be
                  implemented to ensure a unique HW address."
               2. Setting the LAA bit can be done by using a 0A hex as the
                  first digit instead of 08.
               3. /usr/sbin/ifconfig hme1 ether 0a:0:20:00:01

       6. How do I determine if local mac addresses are in use on my host?

           a. /usr/sbin/prtconf -pv | /usr/bin/grep local-mac-address
