Improve VNIC performance on Tx path by immediate packet transmission

Don't postpone Tx if the Tx lock can be acquired now.
This gives 3x better performance on egress.

Add support for hardware Tx and Rx checksums to VNIC driver

- The network controller verifies Rx TCP/UDP/SCTP checksums by default.
Communicate this to the stack when the packet is not marked as erroneous
to avoid redundant checksum calculation in kernel.
- It is not uncommon to get the mbuf with m_len that is less than
the minimal size for the IP, TCP, UDP, etc. when HW checsumming
is enabled. To avoid data corruption performed by the HW that is
intended to write IP and TCP/UDP/SCTP checksums to the data segment,
the mbuf needs to be pulled up by the required number of bytes.
- Make sure that one can modify the mbufs that require checsum calculation
rather than check for NULL mbuf on each transmission.

Introduce initial support for Cavium's ThunderX networking interface

- The driver consists of three main componens: PF, VF, BGX
- Requires appropriate entries in DTS and MDIO driver
- Supports only FDT configuration
- Multiple Tx queues and single Rx queue supported
- No RSS, HW checksum and TSO support
- No more than 8 queues per-IF (only one Queue Set per IF)
- HW statistics enabled
- Works in all available MAC modes (1,10,20,40G)
- Style converted to BSD according to style(9)
- The code brings lmac_if interface used by the BGX driver to
update its logical MACs state.
