Add NIC SR-IOV and performance tuning units

sriov-enp4s0.service allocates VFs on the ixgbe ports at boot and applies
persistent VF MACs via set-ixgbe-vfmacs-enp4s0.sh, so guests keep stable
addresses across host reboots. The VF MAC assignments are currently all
commented out.

nic-performance-tweaks.service raises ring buffers and txqueuelen on the
uplinks and vmbr0.

unused/ holds the equivalent pair for the retired enp130s0 adapter.
