 要开发eBPF程序，您需要安装以下软件和工具：
 
 - Linux 内核：由于eBPF是内核技术，因此您需要具备较新版本的Linux内核（至少 4.8 及以上版本，建议至少在 5.15 以上），以支持eBPF功能。
-    - 建议使用最新的 Ubuntu 版本（例如 Ubuntu 23.10）以获得最佳的学习体验，较旧的内核 eBPF 功能支持可能相对不全。

 - LLVM 和 Clang：这些工具用于编译eBPF程序。安装最新版本的LLVM和Clang可以确保您获得最佳的eBPF支持。
 
 eBPF 程序主要由两部分构成：内核态部分和用户态部分。内核态部分包含 eBPF 程序的实际逻辑，用户态部分负责加载、运行和监控内核态程序。

-This code defines an eBPF program that can capture and process packets through Linux TC (Transmission Control). In this program, we limit it to capture only IPv4 protocol packets, and then print out the total length and Time-To-Live (TTL) value of the packet using the bpf_printk function.Here is the translated text:

 What needs to be noted is that we use some BPF library functions in the code, such as the functions bpf_htons and bpf_ntohs, which are used for conversion between network byte order and host byte order. In addition, we also use some comments to provide additional points and option information for TC. For example, at the beginning of this code, we use the following comments:

 1. **缺乏内核集成**：DPDK 及其他内核绕过解决方案无法利用现有的内核网络功能，开发者必须在用户空间重新实现许多协议和功能。
 
 2. **安全边界**：这些绕过技术破坏了内核的安全模型，使得难以利用内核提供的安全工具。
-
 3. **用户空间与内核的转换开销**：当用户空间数据包处理需要与传统内核网络交互时（例如基于套接字的应用程序），数据包必须重新注入到内核中，增加了开销和复杂性。
-
 4. **专用 CPU 使用**：为了处理高流量，DPDK 和类似解决方案通常需要专用的 CPU 核心来处理数据包，这限制了通用系统的可扩展性和效率。
 
 另一个替代 XDP 的方法是使用 Linux 网络栈中的 **内核模块** 或 **挂钩**。虽然这种方法可以很好地集成现有的内核功能，但它需要大量的内核修改，且由于在数据包处理管道的后期运行，无法提供与 XDP 相同的性能优势。
