问题描述：

Anolis 8.6系统使用intel提供的ice第三方驱动，网卡为intel的E810网卡，执行配置网卡多

队列命令后，网卡显示down的状态，再执行systemctl restart network后，网卡显示up状态

，如果执行rmmod ice ,随后执行modprobe ice，此现象无法复现。可见附件图片。

OS:       Anolis 8.6
kernel:   4.19
网卡型号：Intel Corporation Ethernet Controller E810-XXV

复现步骤：
1、执行命令：ethtool -L enp33s0f0 combined 8
2、ip a查看网卡状态
发现enp33s0f0变为down状态
3、执行systemctl restart network
4、发现enp33s0f0变为up状态

以上步骤可以重复复现

5、执行rmmod ice & insmod ice

发现如上的问题不再复现。

@songkai, would you please help to upload the below information to IPS#00785343 for further support from Intel network engineer? Thanks.

os and version? (cat /etc/*release*)
driver version? (ethtool -i ethxxx)
nvm image e-track id? ( ethtool -i ethxxx)
configuration of the port in os? (/etc/systemconf/network-script/if-xxxx)
has NetworkManager run or not?
any logs in dmesg?

patch ab4ab73fc1ec引入的bug，ice driver在设置link-down-on-close flag后在ice_down()函数中会误将端口down掉，
Fix patch：8ac7132704f3fbd2095abb9459e5303ce8c9e559, 打此patch测试95次ethtool 命令问题验证通过

另外，bugzilla log中warning “Affinity broker due to vetctor space exhaustion”与此问题无关，该warning的原因是
执行此问题的ethtool会重新分配queue以及queue对应的中断，在中断affinity流程中触发了apic的一个bug产生的warning，修复
此warning的patch为：190113b4c6531c8e09b31d5235f9b5175cbb0f72
