I have a machine I just deployed w/ tg3 interfaces, I have setup bonding
on this same line of server (HP DL380 G4) a million times. I saw there were
changes recently to how you configure a bond and have my setup configured
according to: http://kbase.redhat.com/faq/docs/DOC-7431
The HP switch has a LACP trunk defined on the two ports. Problem is, when
rebooting, I need to issue a `service network restart` to gain connectivity?
There is nothing in messages that looks wrong? Anyone have an idea?
