브로드컴 NIC 의 SR-IOV 활성화

아메리칸 메가트렌드 바이오스에서 on-board 된 NIC 의 SR-IOV 활성화



onboard NIC의 SR-IOV 활성화

바이오스에서 온보드 된 NIC의 SR-IOV을 활성화 할 수 있다.

아메리칸 메가트렌드 바이오스의 경우 다음 메뉴에서 설정할 수 있다; BIOS → Advanced → *** Ethernet Controller → Device Configuration → SR-IOV Enabled


장치 확인

ifconfig -a | grep -i UP
lspci -v | grep -i broadcom
lspci -v | grep -i broadcom -A 30
cat /sys/class/net/enp129s0f0/device/sriov_totalvfs

LINE 31 에서 SR-IOV 기능이 활성화 된 것을 확인할 수 있다.

LINE 35-36 에서 브로드컴의 커널 드라이버 모듈이 bnxt_en 임을 확인할 수 있다.

LINE 39-40 에서 VF (Virtual Function) 개수를 확인할 수 있다.
