Emulex OCm14102-u2-d in M620 and vSphere 5.5 Issue

If you use the latest 5.5u2 DELL iso from our ftp, boot up the host with either NPAR on or off, the nic’s in iDRAC will show up/up, the switch will say up/up, however vSphere will say Down, half-duplex.

To resolve this issue run esxcfg-vnics –a <vnic> to set it to auto-negotiation (the driver seems to have overridden this). This will make the nic’s come online. It seems to survive reboots.
