Linux系统重启后，BCM57416（Broadcom NetXtreme-E）网卡会无法连接网络，在日志中可以发现如下告警：
Oct 10 10:37:02 yunweixia.com kernel: bnxt_en 0000:5e:00.0 p3p1: NIC Link is Up, 10000 Mbps full duplex, Flow control: none Oct 10 10:37:02 yunweixia.com kernel: bnxt_en 0000:5e:00.1 p3p2: NIC Link is Up, 10000 Mbps full duplex, Flow control: none Oct 10 10:37:02 yunweixia.com kernel: bnxt_en 0000:5e:00.0 p3p1: NIC Link is Down Oct 10 10:37:02 yunweixia.com kernel: bnxt_en 0000:5e:00.1 p3p2: NIC Link is Down
一、先决条件
- 1.Red Hat Enterprise Linux 9.4
- 2.BCM57416 with PCI ID [14e4:16d8 with bnxt_en driver
- 3.firmware-version: 20.6.151.0
二、解决方案
1.检查网卡型号
# lspci | grep -i ether
01:00.0 Ethernet controller [0200]: Broadcom Inc. and subsidiaries BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet Controller [14e4:16d8] (rev 01)
Product Name: Broadcom Adv. Dual 10GBASE-T Ethernet
2.检查固件版本
# ethtool -i driver: bnxt_en version: 5.14.0-427.37.1.el9_4.x86_64 firmware-version: 20.6.151.0 <---------- expansion-rom-version: bus-info: 0000:01:00.0 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes supports-priv-flags: no
3.故障现象
p3p1网卡和p3p2网卡在启动并激活配置文件1秒后，链接关闭。每次重启时，此行为都是一致的。

4.解决方案
如果BCM57416[14e4:16d8]正在使用较旧的NIC固件（firmware-version: 20.6.151.0），这可能会导致启动时宕机等意外行为。测试环境中将固件升级到“22.21.07.80”后，问题得以解决。
