git pull了一下最新的代码，然后make modules_install install以后，重启系统以后发现无线网卡使用不了，这个时候就需要解决问题
首先下载了一个压缩包，编译的时候，在/drivers/net/wireless/ipw2x00/ipw2100.c的6060行，遇到了没有成员的问题，于是将该文件copy到linux-2.6源代码目录下，然后建立一下源代码tags表，接着就用vim逐级查进去

其中6061行代码以前没有被注释掉，我这里给注释掉了，为了能够暂时使用，所以这里注掉了，以后遇到问题再说，没问题就先放着
为什么我注掉他呢？跟进去看一下
首先看priv这个结构

里面包含下一个结构
但是这个wireless结构里就没有ieee80211成员了
421 struct iw_public_data {
422 /* Driver enhanced spy support */
423 struct iw_spy_data * spy_data;
424 /* Legacy structure managed by the ipw2x00-specific IEEE 802.11 layer */
425 struct libipw_device * libipw;
426 };
427

但是这个
iw_public_data在我的linux-2.6的源代码里，我实在不忍心修改，呵呵，就改一下驱动的代码吧。
