* Fix bug where SFP Rate Select pins could be set incorrectly, resulting in no
  link with certain SFPs

20180215
* Set PPS termination to disabled by default

20171121
* Resolve occasional PCIe initialization failure at card reset

20171019
* Enable PCIe RX equalization to improve PCIe link performance/stability
* Add support for PXE boot (legacy BIOS only, no UEFI support currently)
* Add support for reloading firmware after flashing without requiring host reboot
* Resolve issue with transmitting at 100/10Mbit using some GBICs
* Fix bug where PPS timestamp could be read incorrectly

20170530
* Improve Flash programming settings to address occasional programming failure

20170116
* Fix bug where the host could lock up if a 1G link was disconnected/interrupted
  during the middle of receiving a frame
* Add support for local loopback of port traffic back to host
* 1G autoneg enable status is now read back from the card correctly

20160420
* Fix bug where MAC rules and IP rules with same ID would collide in hardware,
  resulting in traffic matching either rule being forwarded to the one buffer
* Increase TX command queue depth to 256
* Improve algorithm used to bring RX link up to avoid flapping when no signal

20151025
* Fix bug where packets that are received on a port, but which are not destined
  the local MAC address, would could issues with subsequent packets, including
  incorrect packet lengths

20151009
* Fix timestamping bug (timestamp attached to wrong packet)
