Mellanox 100Gb switch - default login and change management IP

Connect via serial port to change the management IP address.  Use the RJ45 to DB9 cable, 115200 baud.

Initial IP configuration must be done via serial port or DHCP.

NOT FOR USE IF CONNECTED VIA IP

After "no interface mgmt0 dhcp" the IP will disconnect and you will be locked out to set the static IP.  Maybe these two steps should be flipped but it is yet to be tested.
