After a round of BIOS/firmware upgrades I've a Network Adapter that whilst detected by ESXi is not available for use.
Intel I350 Gigabit Backplane (not detected)
Broadcom Gigabit NetXtreme BCM5720
VMWare ESXi 5.5 Update 1
Output of esxcfg-nics -l, the vmnics are unavailable for use
If I run an lspci | grep vmnic the result is below
To date I've tried this KB article (2019871
) and a full reinstall of ESXi 5.5 Update 1 without success.
Any assistance would be greatly appreciated.
