少なくとも linux-hwe-generic-trusty で linux-image-4.4.0-101-generic 入れてる状態だと標準で入ってる ixgbe ドライバーで勝手に動いた。

dmesg は以下の通り。

因みに、pci-e のコネクタから遠い方が 02:00.0 で、近い方が 02:00.1 だった。

同じく Utuntu 16.04.03LTS に玄人志向 GbEX-PCIE 挿したマシンに対して netperf かけてみたところ以下のような値が出た。

$ netperf -H 192.168.1.30 -l 15

反対向き 10Gbps 越えという不思議な結果が出てたけど、こっちは普通っぽい。
