Changing of WMM queue parameters forbidden for IBSS interfaces

Changing of WMM queue parameters forbidden for IBSS interfaces

[Jörg Pommnitz]

Hello all,

I'm trying to change the WMM parameters for an IBSS network. I'm
adding a command to set txq_params to iw. Sadly the current kernel
code explicitly denies this for interfaces other than AP and P2P (see
http://lxr.free-electrons.com/source/net/wireless/nl80211.c#L2279).

Is there a reason why this should not be done for IBSS interfaces?


Thanks in advance
  Joerg

Sorry, wrong line in the link, the correct line is:

I guess the whole thing was just ignored - we should also *adopt* the
EDCA parameters when joining an IBSS network, which I don't think we do
either.

I'm not sure we can actually modify them on the fly though - since
adoption is required, such changes would have a hard time propagating
through.

If really necessary, we'd have to implement adoption and probably only
allow setting it at IBSS creation time.
