====== FreeBSD 11でQSFP+トランシーバモジュールの詳細情報を見てみる ======

===== 試した環境 =====

  * FreeBSD 11.2-RELEASE-p7
  * ConnectX-3 Pro EN
  * 40GBASE-SR4 QSFP+光トランシーバ
    * AVAGO AFBR-79EQPZ-HT1
    * 10GtekのMC2210411-SR4相当品

ifconfigのverboseを利用しているだけなので、SFF-8436準拠のQFSP+モジュールなら何でも表示できると思う。それこそ、規格に準拠さえしてれば、SFPだろうと何だろうと動くと思われる。

===== 手順 =====

ifconfigに-vvvオプションを渡すだけ。-vで詳細情報表示になるわけだけど、vの数を増やすと詳細度が増す。
