This patch implements multiple pieces of functionality:
1. Added ice_vsi_sync_filters, which is called through the service task
to push filter updates to the hardware.
2. Add support to enable/disable promiscuous mode on an interface.
Enabling/disabling promiscuous mode on an interface results in
addition/removal of a promisc filter rule through ice_vsi_sync_filters.
3. Implement handlers for ndo_set_mac_address, ndo_change_mtu,
ndo_poll_controller and ndo_set_rx_mode.
This patch also marks the end of the driver addition by bumping up the
driver version.

This patch adds support for VLANs. When a VLAN is created a switch filter
is added to direct the VLAN traffic to the corresponding VSI. When a VLAN
is deleted, the filter is deleted as well.
This patch also adds support for the following hardware offloads.
1) VLAN tag insertion/stripping
2) Receive Side Scaling (RSS)
3) Tx checksum and TCP segmentation
4) Rx checksum

This patch implements ice_start_xmit (the handler for ndo_start_xmit) and
related functions. ice_start_xmit ultimately calls ice_tx_map, where the
Tx descriptor is built and posted to the hardware by bumping the ring tail.
This patch also implements ice_napi_poll, which is invoked when there's an
interrupt on the VSI's queues. The interrupt can be due to either a
completed Tx or an Rx event. In case of a completed Tx/Rx event, resources
are reclaimed. Additionally, in case of an Rx event, the skb is fetched
and passed up to the network stack.

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.
