I just ran an upgrade on a host from 6.5 to 7 using life cycle manager and after upgrade it is not seeing the networks card. it has the BCM5719 Gigabit Ethernet cards. It is on the HCL but it was using a tg3 driver on 6.5 (rather than the ntg3, I think this was due to previous driver issue). do you think this is the issue? Dont the drivers get updated during the esx upgrade?
