Hi, Can anyone tell me where I can find some description/intro/info about xfrm? Or just explain it to me? What is it used for (maybe, how?)? What do I have to read to understand what it is? What does the name "xfrm" stand for, anyway, transform? :) I see in the kernel that it is used for security/tunneling things. Thanks in advance, Gabor - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
