我正在尝试了解我的 Alpha wlan 卡的行为，通常它运行良好，但我的问题与更高级的主题有关。

我来自无线芯片组验证领域，据我所知，大多数无线芯片组在生产阶段都经过校准，并且这些校准值会写入 eeprom。尝试理解 modinfo 中粘贴的行以及正确的配置是什么。
前两行选择的模式是什么？0/1/2？
rtw_tx_pwr_lmt_enable
rtw_tx_pwr_by_rate
其余 2g/5g 线的含义是什么？驱动程序未使用校准值吗？
Alpha 卡在 2.4 和 5 ghz 两个频段上工作，每个频段一个天线，每个频段可能有 x2 个 RF 路径 (Tx/Rx)，那么为什么每个频段有 ABCD 个路径？这是真的吗？
