Hi folks, I have a board with 2.6.27.5 kernel and I want to use Asus N53 USB WiFi dongle on it in direct mode. I have used rt5572sta driver ver 2.6.0.1 and the dongle is able to work in infra and ad hoc mode, but direct mode is not working. Only ra0 interface is made when the module is inserted, interface p2p0 needed for direct mode does not comes up. I can not change my kernel version as all my running applications can not be ported to newer kernels. Thanks in advance for your help! Regards, A Sharma

Oh? What applications are you stuck with that can't move to newer kernels? We're usually pretty damned good about backward compatability in new releases.
Hi Valdis, Thanks for your reply. I do not want to change kernel. Help regarding direct mode working of Ralink RT3572 chipset is all I need. Regards, A Sharma On 18 December 2014 at 20:07, <Valdis.Kletnieks@vt.edu> wrote:

Hi Abhishek Thanks for your reply I do not want to backport driver and APIs to buggy old kernels. Fixing broken backward compatibility is all I need. Regards. On Thu, Dec 18, 2014 at 3:48 PM, Abhishek Sharma <asharma.es@gmail.com> wrote:

"do not want to" is very different from "applications can not be ported to newer kernels". Please realize that the Linux kernel developers have spent the last decade ensuring that you should be able to update to the latest kernel version with no problems or changes needed in your applications. Lots of companies now realize this and have no problem updating to a newer kernel, while running their old applications. So please don't spread misinformation about how applications will break with new kernel versions, that is almost always not a true statement. thanks, greg k-h

Abhishek, I am to agree with Greg KH here. The kernel community does a very good job of not breaking APIs for applications or regressions. Linus also has openly stated he will not accept any patches in the main line kernel tree if they break user space so you should be fine. Further more to be honest I am very impressed with the amount of how little APIs or regressions we get compared to the amount of commits. Abhishek, in addition this seems more like you don't know or are afraid of compiling the kernel over anything else. If you want post lsmod output from your system so I can help teach you how to build the kernel correctly. Nick

If it's a custom board, bringing up new kernel versions can be a quite daunting task that the management of engineering organizations is more often than not loathe to undertake. It can take a lot of education to convince them that the pain and unpredictable development schedule hit of a kernel upgrade is more than compensated for by the increases in stability and features one gets when one goes through the process.

Jeff, You are a 100% correct. I am assuming it wasn't a custom board but if it is them, you are right it's a lot of engineering work and time. Nick

You do realize just how old, obsolete, and insecure that kernel version is, right? If you are stuck with that version, please get help from the company you are paying for support from to do this backporting work, as they are the only ones that can do that for you. Best of luck, greg k-h
