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
