docs: networking: device drivers: convert neterion/vxge.txt to ReST

- add SPDX header;
- adjust titles and chapters, adding proper markups;
- comment out text-only TOC from html/pdf output;
- mark code blocks and literals as such;
- adjust identation, whitespaces and blank lines where needed;
- add to networking/index.rst.

 This Linux driver supports all Neterion's X3100 series 10 GbE PCIe I/O
 Virtualized Server adapters.

 The X3100 series supports four modes of operation, configurable via

-	Single function mode
-	Multi function mode

 The functions share a 10GbE link and the pci-e bus, but hardly anything else
 inside the ASIC. Features like independent hw reset, statistics, bandwidth/
 priority allocation and guarantees, GRO, TSO, interrupt moderation etc are

        X3100 Series supports MTU up to 9600 bytes, modifiable using
        ip command.
 
 v)   Offloads supported: (Enabled by default)
-       Checksum offload (TCP/UDP/IP) on transmit and receive paths
-       TCP Segmentation Offload (TSO) on transmit path
-       Generic Receive Offload (GRO) on receive path

        For better Rx interrupt moderation.
 
 viii)RTH (Receive Traffic Hash): (Enabled by default)

        Receive side steering for better scaling.
 
 ix)  Statistics

        Comprehensive MAC-level and software statistics displayed using
        "ethtool -S" option.
 
 x)   Multiple hardware queues: (Enabled by default)
