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-

から、Date: 07/15/2015　版の　em-7.5.2.tar.gz　をゲット

em-7.5.2.tar.gz

FreeBSD 10.1-RELEASE-p19 な　NEC Express5800/110b でコンパイル。

if_em.ko_FreeBSD10_1

http://subnets.ru/blog/?p=1138

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

root@blackcube2:~ # pciconf -l -v
em0@pci0:0:25:0:        class=0x020000 card=0x83891033 chip=0x10ef8086 rev=0x06 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82578DM Gigabit Network Connection'
    class      = network
    subclass   = ethernet

if_em.ko 入れ換え後

root@blackcube2:~ # pciconf -l -v
em0@pci0:0:25:0:        class=0x020000 card=0x83891033 chip=0x10ef8086 rev=0x06 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82578DM Gigabit Network Connection'
    class      = network
    subclass   = ethernet

なんの変化も無し？？？
