Enabling SRIOV VFs:
Only the PFs are automatically enabled. If a PF supports SR-IOV, the PF(vmknicX) is part of the output of
the command shown below.
esxcli network sriovnic list
To enable one or more VFs, the driver uses the module parameter "max_vfs" to enable the desired number
of VFs for PFs. For example, to enable four VFs on PF1:
esxcfg-module -s 'max_vfs=4' bnxtnet (reboot required)
To enable VFs on a set of PFs, use the command format shown below. For example, to enable four VFs on
PF 0 and 2 VFs on PF 2:
esxcfg-module -s 'max_vfs=4,2' bnxtnet (reboot required)
The required VFs of each supported PF are enabled in order during the PF bring up. Refer to the VMware
documentation for information on how to map a VF to a VM:
