The impact of the VXLAN overlay networks on netqueue behavior (2032810)

Details

When VXLAN is enabled, all virtual machine traffic is processed through the PNIC queue 0. In this configuration, although PNIC supports multiple netqueue instances and some netqueues might be allocated for other traffic, all the received traffic is still handled by queue 0.

In the case of an RSS-capable driver, apart from allocating RSS netqueues, additional netqueues get allocated but remain unused. Only RSS netqueue is used to process all the VXLAN traffic.
