NEC Express5800 の onboard em(4)が落ちるので、ドライバーを最新版にしてみる。

NEC Express5800 の em のドライバーはこちら、
http://www.express.nec.co.jp/linux/distributions/confirm/option/nic/nic.html
にありますが、手元のFreeBSD9.x以降の環境ではエラーでコンパイルできませんでした。ググって、
https://downloadcenter.intel.com/download/17509/Network-Adapter-Gigabit-Base-Driver-for-FreeBSD-
https://downloadcenter.intel.com/ja/download/17509
から、Date: 07/15/2015 版の em-7.5.2.tar.gz をゲット
FreeBSD 10.1-RELEASE-p19 な NEC Express5800/110b でコンパイル。

生成したif_em.koを、
mv if_em.ko /boot/modules
して、
echo 'if_em_load="YES"' >> /boot/loader.conf
echo 'WITHOUT_MODULES=em' >> /etc/make.conf
reboot
if_em.ko 入れ換え前

なんの変化も無し？？？

dmesgでも
