NetXtreme II BCM5716 网卡瞬断

最近有台 R510 服务器。配置 NetXtreme II BCM5716 网卡，

网卡 经常 无法 down  up

bnx2 0000:01:00.1: eth1: NIC Copper Link is Down
bnx2 0000:01:00.1: eth1: NIC Copper Link is Up, 1000 Mbps full duplex

从错误上来看，应该是跟 bnx2 驱动 有关。

modinfo bnx2

直接升级 bnx2 驱动  http://ldriver.qlogic.com/driver-srpms/netxtreme2/

[root@aikaiyuan ~]#  wget http://ldriver.qlogic.com/driver-srpms/netxtreme2/netxtreme2-7.13.04.1-1.rhel6u5.src.rpm

[root@aikaiyuan ~]#  rpm -ivh netxtreme2-7.13.04.1-1.rhel6u5.src.rpm
[root@aikaiyuan ~]#  cd ~/rpmbuild  
[root@aikaiyuan rpmbuild]# rpmbuild -bb SPECS/kmp-netxtreme2.spec

[root@aikaiyuan rpmbuild]# rpm -ivh ~/rpmbuild/RPMS/x86_64/kmod-netxtreme2-7.12.37.1-1.rhel6u5.x86_64.rpm

重启服务器，再次执行 modinfo bnx2  已经升级到最新版本。
