[c-nsp] NX-OS - Fabric Path

[Church, Charles]

Just be careful about connecting the mgmt0 interfaces to anything prior to
configuring them.  The default IP address of 10.1.1.50 on them (at least on
the 4.2 5000s) will cause a spectacular ARP storm when they conflict with
each other, like when you attach several unconfigured ones to the same
network.  Several thousand PPS, eventual reloads, etc.  Our installation
guys got ahead of the config guys in our new DC, nice little mess it made.
Not sure why they put a default address on them, hope it's something they
correct in the future.

Yes, but Nexus hardware is the right platform if you don't want to loose any
packet in your DC ;)
