net_pkt: Extend packet abstraction as required by e1000e functionality
This patch extends the TX/RX packet abstractions with features that will
be used by the e1000e device implementation.
Changes are:
1. Support iovec lists for RX buffers
2. Deeper RX packets parsing
3. Loopback option for TX packets
4. Extended VLAN headers handling
5. RSS processing for RX packets
