"mac80211.ko" and "cfg80211.ko" compatibility issue.

"mac80211.ko" and "cfg80211.ko" compatibility issue.

[Akira Nonaka]

Hi all,

I have a problem with the compat-wireless. It seems "mac80211.ko" and
"cfg80211.ko" are not compatible with the ones in main line kernel. In
my case, it is kernel 3.4.9(Fedora 16).

I want to use  compat-wireless version of "mac80211.ko" and
"cfg80211.ko" for Realtek rtl8723ae but for other wireless cards, I want
to use main line kernel version of "mac80211.ko" and "cfg80211.ko".

This switch should happen at the boot time since I need to support a lot
of PCs with the single kernel.

Can someone tell me where the "modprobe rtl8723ae (and for other PCI
devices)" get called when I run the kernel on the PC with rtl8723
wireless card? I searched the entire scripts under /etc but I could not
find.

What is the right thing to do? I appreciate your advise.

This is expected and pretty much by design.

Why? Are the drivers for these other cards not available in compat-wireless?

Thanks,

Hi Julian,

Well, We consider the option of using the entire compat-wireless drivers. However, we are planning the minor update of our product toward the end of the year and I thought it will be nice if I can keep the change minimum.

In general, the drivers in compat-wireless are more stable and have
more features than the versions in older kernels. (it is a back-port
of newer wireless drivers after all)

I would expect that you'll spend more time working out a solution to
use it for a single driver than you'd spend testing it on the hardware
you intend to support.

Thanks,

I agree. If you want to change only rtl8723ae, then you will need to backport it 
to kernel 3.4.9 yourself. I have no idea how much work that would be, but I have 
no interest in doing it.

Julian, Larry

Thank you for your advise. I will consider taking your suggestion.
