continue;
}
为什么是HCI_USER_CHANNEL这个标志就要将skb删除？

用朴实无华的语言，结合实际操作，毫无保留的分享Bluez协议栈的运行原理和框架，Bluez协议栈并不难，但是他的代码结构很复杂，如果自己摸索的话，很有可能会形成从入门到放弃的结局，另外理解Bluez协议栈需要对蓝牙...

目录一、引言二、HCI框架三、pcm_read简要分析一、引言最近一直在分析蓝牙驱动，发现在底层驱动与上层协议栈间还有一层HCI，主机控制层，两者之间通过HCI协议通讯而Linux也将HCI协议抽象层了一个框架。为上层提供一个统一的接口，让上层协议不依赖于具体硬件的实现。HCI在硬件中的固件与HCI在主机端的驱动通信方式有多种，比如像 UART、USB和PC Card等等。hci_core.c相当于一个框架，用于把各种具体通信方式绞合起来，并提供一些公共函数的实现。今天就来简单的分析一下二
