sfc: add ndo_set_vf_link_state() function for EF10
Exercised with
"ip link set <PF intf> vf <vf_i> state {auto|enable|disable}"
Sets the reporting policy for VF link state to either
- mirror physical link state
- always up
- always down
get VF link state mode in efx_ef10_sriov_get_vf_config
Exercised by
"ip link show <PF intf>";
output will include a line like
vf 0 MAC 12:34:56:78:9a:bc, link-state auto
