比亚兹AX286/UK15无线网卡(aic8800)的Ubuntu22.04驱动

仓库地址：https://github.com/lamaper/Biaze-AX286-UK15-aic8800-dirve-for-Ubuntu22.04

前言

事情的起因是我的E3神机时不时在学校断连，我不得不每两三天就跑到我的神秘打野点去修一下。关键是我的E3神机并没有显示器， 每次连接都是用HDMI+采集卡，用我笔记本的OBS当显示器，一通折腾让人恼火不已。 我猜测可能是Windows的奇妙策略影响了联网（后来发现不是），于是我便直接将其重装成Ubuntu22.04， 还方便以后直接ssh连接。

由于神秘打野点没有网口，我只能通过USB无线网卡来联网，重装之前京东客服跟我确认说是linux免驱动直接用， 没想到装好了连不上，客服磨磨唧唧发出来个网盘链接，我直接一通操作：

1

sudo dpkg -i aic8800fdrvpackage_amd64.deb

发现不太对劲，怎么老报错，一查发现我安装没联网，整个电脑没有build-essential，这逆天完了。

我陷入了死循环，没网就装不了build-essential，没有它我又装不上驱动连不了网。于是我又费尽心思把神机搬回宿舍， 插上网线，再次一通操作

1

3

sudo apt update && sudo apt install build-essential

sudo dpkg -i aic8800fdrvpackage_amd64.deb

结果报错更彻底了。经过研究我发现，这个驱动甚老，不支持我2204，尽管我已经想到兼容性问题没装2404，也没逃过这劫。

于是便有了如下维修步骤：

对于Ubuntu22.04如果遇到如下报错，则需要更新gcc版本

解决方法：

  1. 安装 GCC 12 及其关联工具
1
2

sudo apt update
 sudo apt install gcc-12 g++-12
  1. 设置系统默认使用 GCC 12
    1

     sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-12 100 --slave /usr/bin/g++ g++ /usr/bin/g++-12
  2. 卸载残留并重装
1
2

 sudo dpkg -r aic8800fdrvpackage
 sudo dpkg -i aic8800fdrvpackage_amd64.deb

在修正之前需要说明，此时修正不能卸载原来的deb安装包，我们要在安装目录中修改代码，所以也不能使用dpkg命令，全程使用：

1

sudo make -C /lib/modules/$(uname -r)/build M=$PWD ARCH=x86_64 CROSS_COMPILE= KCFLAGS="-w" modules

在/AIC8800/drivers/aic8800目录下操作。

当输出如下内容的时候，视为正确编译：

Ubuntu 22.04 使用了 6.8.0 内核，ieee80211_amsdu_to_8023s 这个函数的定义在较新的内核版本中发生了改变，增加了一个参数。官方的 aic8800 驱动源码是 2023 年的老版本，还在按旧版内核的方式调用这个函数，参数传少了，所以编译器直接报错。

需要修改/AIC8800/drivers/aic8800/aic8800_fdrv/rwnx_rx.c

too few arguments to function ‘cfg80211_ch_switch_notify’

cfg80211_ch_switch_notify()参数过少，同样是内核升级导致接口变换，新内核为了支持 WiFi 7 的 MLO 多链路特性，在这类函数中间塞入了一个 link_id 参数。对我们普通网卡来说，传 0 即可。

#else
                cfg80211_ch_switch_notify(vif->ndev, &csa->chandef);

多加了个0。

如果想要代码有可扩展性，可以保留上面内核版本判断条件，自己添加一个6.5.0内核的条件，这里不再赘述（能用就行）

static int rwnx_cfg80211_change_beacon(struct wiphy *wiphy, struct net_device *dev,
                                       struct cfg80211_ap_update *ap_info)
{
    struct cfg80211_beacon_data *info = &ap_info->beacon;
    struct rwnx_hw *rwnx_hw = wiphy_priv(wiphy);
    struct rwnx_vif *vif = netdev_priv(dev);
    struct rwnx_bcn *bcn = &vif->ap.bcn;
    struct rwnx_ipc_elem_var elem;

注意我修改了形参的最后一个，并且在第一行新增了struct cfg80211_beacon_data *info = &ap_info->beacon;。

/AIC8800/drivers/aic8800/aic8800_fdrv/rwnx_mod_params.c: In function ‘rwnx_custregd’:
/AIC8800/drivers/aic8800/aic8800_fdrv/rwnx_mod_params.c:1711:32: error: ‘REGULATORY_IGNORE_STALE_KICKOFF’ undeclared (first use in this function)
1711 |  wiphy->regulatory_flags |= REGULATORY_IGNORE_STALE_KICKOFF;
   |                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

这又是一个 Linux 内核版本更迭的历史遗留问题。REGULATORY_IGNORE_STALE_KICKOFF 是旧版内核里用来处理 WiFi 国家/地区射频管制（Regulatory Domain）的一个标志位。但是在 6.8 内核里，官方直接把它从底层代码里删除了。对于我们日常使用来说，我们只求网卡能连上局域网发包抓包，根本不需要去管什么国际射频合规性，所以，最简单粗暴且完全无副作用的解决办法就是直接把报错的代码注释掉。

原代码：

#if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 0, 0)
    if (!rwnx_hw->mod_params->custregd)
        return;

    wiphy->regulatory_flags |= REGULATORY_IGNORE_STALE_KICKOFF;
    wiphy->regulatory_flags |= REGULATORY_WIPHY_SELF_MANAGED;

    rtnl_lock();

修改后：

#if LINUX_VERSION_CODE >= KERNEL_VERSION(4, 0, 0)
    if (!rwnx_hw->mod_params->custregd)
        return;

    // wiphy->regulatory_flags |= REGULATORY_IGNORE_STALE_KICKOFF;
    // wiphy->regulatory_flags |= REGULATORY_WIPHY_SELF_MANAGED;

    rtnl_lock();

注意！别改错了！这里有两个wiphy->regulatory_flags |= REGULATORY_IGNORE_STALE_KICKOFF;，如下这段不用改：
