[UNIKRAFT PATCH v2 0/2] Poll based receive based on uk_netdev features

[Sharan Santhanam <sharan.santhanam@xxxxxxxxx>]

uk_netdev_info provides a way to forward driver information to the network 
stack.
We extend the uk_netdev_info with the features field that allows the network 
stack
to perform a poll based received on those driver that do not support interrupt 
based
receive. The patch series is structured as follows:
- The uk_netdev structure allocates network stack scratch pad.
- The uk_netdev_info provides features field to fetch information on the 
feature supported
  on a driver.

Change since v1:
- Select the max of the scratch size
- Rename from enabled to available for the features
