In case of SR-IOV, this vAdaptor must be created for the PF as the vSwitch is allocated on the physical port. So, the call to efx_mcdi_vadaptor_alloc() should be avoided in ef10_nic_init() in SR-IOV flow. To achieve this, for SR-IOV use case, the vSwitch is created before NIC initialization and its handle is used to prevent vAdaptor allocation in ef10_nic_init(). This approach has been taken to minimize the changes in NIC initilization flow. This is also the case with Linux driver where vSwitch creation happens before NIC initialization. Also, when DMA queues need to be allocated for Tx/Rx functionality (MC_CMD_INIT_RXQ / MC_CMD_INIT_TXQ), the correct vPort is selected based on efx_vswitch_t property of efx_nic_t structure - vport corresponding to PF in case of SR-IOV use case and EVB_PORT_ID_ASSIGNED for physical port.
