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。
