Broadcom NIC delays prevent DHCP during Kickstart

[Mann, Andrew]

> Is spanning tree enabled on the switch?

  Is there a conflict with the Broadcom NICs and spanning tree?  We're
using a Cisco 4500 series switch with spanning tree enabled.  2550s,
1750s, 1850s, and 1955 blades are able to quickly bring the NIC up and
start communicating.  2650s and 2950s have about a 30-60 second delay
between the time the NIC is enabled and communication succeeds.  After a
reboot, we have to run through and restart NTP on each of these types of
system since this delay causes the ntp startup to fail.  It's only been
mildly annoying in the past, but getting rid of it would be nice :)
