谁会/proc或者SO_RCVBUF啊？

这里有段话，是我在写ip_queue的程序的时候遇到的

Yes, these are standard Netlink sockets, and you can tune their receive
buffer sizes via /proc, or use the SO_RCVBUF socket option on the file
descriptor.
这是一个外国论坛上拷贝下来的答复，可惜我看不懂他这段答复怎么用：（
我想知道file descriptor如何跟/proc和SO_RCVBUF连起来，应该怎么解释这句话，他们怎
么工作可以设置缓存大小
哪位大侠知道的请给我解释一下，谢谢
