ice: Add support for VLANs and offloads
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
