ice: Configure VSIs for Tx/Rx
This patch configures the VSIs to be able to send and receive
packets by doing the following:
1) Initialize flexible parser to extract and include certain
fields in the Rx descriptor.
2) Add Tx queues by programming the Tx queue context (implemented in
ice_vsi_cfg_txqs). Note that adding the queues also enables (starts)
the queues.
3) Add Rx queues by programming Rx queue context (implemented in
ice_vsi_cfg_rxqs). Note that this only adds queues but doesn't start
them. The rings will be started by calling ice_vsi_start_rx_rings on
interface up.
4) Configure interrupts for VSI queues.
5) Implement ice_open and ice_stop.
