꽂고 켠 김에 기록
장치는 제대로 잡힌건가 드라이버를 어떻게 확인해야 하지?
BCM957810A1008G <- 요게 모델로 알고 있는데 BCM 뒤에 9는 멀까..?

SR-IOV를 켜놓고 VT 안 켜서 켜고 끄고 해봤는데 bnx 관련으로 달라지는건 없다.
두개의 칩셋을 하나의 pciex 보드에 올린 유형인가 두번 초기화 하네?
| $ sudo dmesg | grep -i bnx [ 0.744607] bnx2x 0000:01:00.0: msix capability found [ 0.744788] bnx2x 0000:01:00.0: part number 0-0-0-0 [ 0.892516] [bnx2x_iov_init_one:1210(eth%d)]ARI not supported (check pci bridge ARI forwarding), SRIOV can not be enabled [ 0.894780] bnx2x 0000:01:00.0: 32.000 Gb/s available PCIe bandwidth (5.0 GT/s PCIe x8 link) [ 0.894862] bnx2x 0000:01:00.1: msix capability found [ 0.895288] bnx2x 0000:01:00.1: part number 0-0-0-0 [ 1.031529] [bnx2x_iov_init_one:1210(eth%d)]ARI not supported (check pci bridge ARI forwarding), SRIOV can not be enabled [ 1.033770] bnx2x 0000:01:00.1: 32.000 Gb/s available PCIe bandwidth (5.0 GT/s PCIe x8 link) [ 1.112794] bnx2x 0000:01:00.1 enp1s0f1: renamed from eth1 [ 1.115593] bnx2x 0000:01:00.0 enp1s0f0: renamed from eth0 [ 6.291401] bnx2x 0000:01:00.0 enp1s0f0: using MSI-X IRQs: sp 127 fp[0] 129 ... fp[1] 130 [ 7.339521] bnx2x 0000:01:00.1 enp1s0f1: using MSI-X IRQs: sp 131 fp[0] 133 ... fp[1] 134 [ 62.619485] bnx2x 0000:01:00.0 enp1s0f0: NIC Link is Up, 10000 Mbps full duplex, Flow control: ON - receive & transmit [ 62.672524] bnx2x 0000:01:00.1 enp1s0f1: NIC Link is Up, 10000 Mbps full duplex, Flow control: ON - receive & transmit |
커널 모듈에서는 아래와 같이 bnx2x 모듈로 로드되었고
| $ lsmod | grep bnx bnx2x 1028096 0 mdio 12288 1 bnx2x libcrc32c 12288 1 bnx2x |
케이블을 바꾸어도 watch -n 0 으로 해서 0.2초 간격으로 봐도 저 놈의 link가 떨어지는게 보이지 않는다.
커널로그로도 없고 도대체 어디서 탐지하는거지?

FEC는 Forward Error Correction 의 약자라는데 먼가 CRC 보다 강해 보이는데
이해를 포기(!)
