Subject: [PATCH 00/10] staging: wfx: introduce nl80211 vendor extensions

From: Jérôme Pouiller <jerome.pouiller@...abs.com>

Hello,

This series introduces some nl80211 vendor extensions to the wfx driver.

This series may lead to some discussions:

  1. Patch 7 allows to change the dynamic PS timeout. I have found
     an API in wext (cfg80211_wext_siwpower()) that do more or less the
     same thing. However, I have not found any equivalent in nl80211. Is it
     expected or this API should be ported to nl80211?

  2. The device The device allows to do Packet Traffic Arbitration (PTA or
     also Coex). This feature allows the device to communicate with another
     RF device in order to share the access to the RF. The patch 9 provides
     a way to configure that. However, I think that this chip is not the
     only one to provide this feature. Maybe a standard way to change
     these parameters should be provided?

  3. For these vendor extensions, I have used the new policy introduced by
     the commit 901bb989185516 ("nl80211: require and validate vendor
     command policy"). However, it seems that my version of 'iw' is not
     able to follow this new policy (it does not pack the netlink
     attributes into a NLA_NESTED). I could develop a tool specifically for
     that API, but it is not very handy. So, in patch 10, I have also
     introduced an API for compatibility with iw. Any comments about this?
