查看内核模块加载时参数

[root@localhost dpdk-19.11]# ls /sys/module/rte_kni/parameters/
carrier  kthread_mode  lo_mode
[root@localhost dpdk-19.11]# cat  /sys/module/rte_kni/parameters/*
on
(null)
(null)
[root@localhost dpdk-19.11]# 

当用dmesg|grep e1000查看的信息如下

[ 30.239355] e1000: probe of 0000:02:00.0 failed with error -5
[ 2541.874552] e1000: 0000:02:00.0: e1000_probe: The EEPROM Checksum Is Not Valid

只要在加载驱动的时候加入参数 eeprom_bad_csum_allow=1即可解决问题
查看e1000驱动模块的参数：

modinfo -p e1000

debug:Debug level (0=none,...,16=all)
eeprom_bad_csum_allow:Allow bad EEPROM checksums
copybreak:Maximum size of packet that is copied to a new buffer on receive
KumeranLockLoss:Enable Kumeran lock loss workaround
SmartPowerDownEnable:Enable PHY smart power down
InterruptThrottleRate:Interrupt Throttling Rate
RxAbsIntDelay:Receive Absolute Interrupt Delay
RxIntDelay:Receive Interrupt Delay
TxAbsIntDelay:Transmit Absolute Interrupt Delay
TxIntDelay:Transmit Interrupt Delay
XsumRX:Disable or enable Receive Checksum offload
FlowControl:Flow Control setting
AutoNeg:Advertised auto-negotiation setting
Duplex:Duplex setting
Speed:Speed setting
RxDescriptors:Number of receive descriptors
TxDescriptors:Number of transmit descriptors

修改 /etc/modprobe.conf文件，加入一行：
options e1000 eeprom_bad_csum_allow=1

然后执行这两条命令
modprobe -r e1000
modprobe e1000

即可解决问题。
