this version added support for 2.5 Gbps and 5 Gbps auto-negotiation
for adapters X550 and later. however, for switches that support these speeds (and so advertise) but /do not/ advertise those modes (e.g. Netgear MS-510TX), the changes don't' suffice, and the adapter reverts to 1 Gb/s speed. I enclose a simple change to the *ixgbe_setup_phy_link_speed_generic* function that fixes the issue. Note that the Windows drivers support these speeds out of the box.
