在Centos 6.7系统上安装Hanic网卡，装驱动的时候总显示：
file …… from install of …… conflicts with file from package ……
这种问题是因为Hanic要更改libpcap文件，但又与对应的libpcap-devel的版本冲突造成的。
废了好大劲也没有解决冲突问题，没办法，二选一，只能留Hanic了。
具体步骤如下：
1、用yum卸载已安装的libpcap和libpcap-devel
yum remove libpcap libpcap-devel
2、按照 Hanic网卡安装步骤[附] 安转Hanic网卡驱动。
3、重启计算机。
附：Hanic网卡安装步骤
1.使用 yum install kernel-devel 和 yum update kernel 更新内核。
2.Download the package from support web of Netcope Technologies
(www.netcope.com/support)
3.Connect to the machine with FPGA-100G2 card
4.Run installation script (as root):
# bash hanic4-100g2-1.2.0.bin
5.Stop all SZE applications
6.Stop tsuctl daemon
# pkill tsuctl
7.Run the following command for firmware upgrade:
for 100G2 single-port version with load balancing:
# csboot -f 100 /usr/share/mcs/hanic4/1.2.0/combo-100g2/sdp/hanic-combo100g2sdp.mcs
for 100G2 single-port version:
# csboot -f 100 /usr/share/mcs/hanic4/1.2.0/combo-100g2/sp/hanic-combo100g2sp.mcs
If return failed. Try reboot the system again.
8.安装mcs文件后根据《Hanic网卡信息》查看网卡是否安装成功。
