[Sharan Santhanam <sharan.santhanam@xxxxxxxxx>]

The patch series introduces a tap driver for the linuxu platform. The series is
structured as follows:
- Introduce the uk_netdev interface implemented by the tap driver
- Introduce pseudo tap bus to initialize the driver and probe a tap device.
- The tap device discovered are registered with the uk_netdev.
- Configure the netdevice by creating tap network interface.
- Configure the hw address on the tap device.
- Attach the tap device to a bridge interface.
- Fetch and configure the MTU.
- Check if the promiscuous mode is set
- Fetch the txq/rxq information.
- Configure the tx queue.
- Configure the rx queue.
- Start the tap interface.
- Implement packet receive on the tap interface
- Implement packet send on the tap interface
- Fix the error code difference between Unikraft and linux.
