ath9k and 16 VAP interfaces?

ath9k and 16 VAP interfaces?

[Ben Greear]

Hello,

Has anyone tried making ath9k able to support 16 vAP interfaces on a single
radio?  I seem to recall that there were limitations regarding beacon
timers and such, and that is why the current limit is 8?

Thanks,
Ben

Do you mean AP interfaces as required for multiple BSS/SSIDs?

I'm running a patched ath9k to have hostapd run >8 BSS on a single radio.
It works fine since years.

Yes, I'd love to see any patches you can share on this as well.

Re: ath9k and 16 VAP interfaces?

Hi,

I'm using [1]. I was seeing some trouble with powersave + broadcasts, so 
I added [2], so that the queue would get empty faster.

Regards,
M. Braun

Re: ath9k and 16 VAP interfaces?

[Ben Greear]

Hello,

I'm finally getting around to trying this.

One thing, the second patch won't compile due to missing ath9k_set_moredata method.

I see it is implemented here:

http://git.fem.tu-ilmenau.de/?p=fem-wlan.git;a=blob;f=package/kernel/mac80211/patches/310-ath9k-fix-moredata-bit-in-PS-buffered-frame-release.patch;h=b2a74ccbacb29115bede4806006f3265f54cb31c;hb=refs/heads/femwlan_stage2.kernel4.9

I guess I should apply this one...maybe more?

Any idea if any of these patches should be submitted upstream?

Thanks,
Ben
