Many devices send event notifications for the IO queues,
such as tx and rx queues, through event queues.
Enable a privileged owner, such as a hypervisor PF, to set the number
of IO event queues for the VF and SF during the provisioning stage.
example:
Get maximum IO event queues of the VF device::
$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1
function:
hw_addr 00:00:00:00:00:00 ipsec_packet disabled max_io_eqs 10
Set maximum IO event queues of the VF device::
$ devlink port function set pci/0000:06:00.0/2 max_io_eqs 32
$ devlink port show pci/0000:06:00.0/2
pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1
function:
hw_addr 00:00:00:00:00:00 ipsec_packet disabled max_io_eqs 32
