2017-07-28rsi: remove unnecessary check for 802.11 management packetPrameela Rani Garnepudi
The function rsi_mgmt_pkt_to_core() is for passing the 802.11 management frames to mac80211. So, it is unnecessary to check again for the frame type 802.11 management in this function. It can be checked before passing to this function.

2017-06-25Merge tag 'wireless-drivers-next-for-davem-2017-06-25' of ↵David S. Miller
git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== wireless-drivers-next patches for 4.13 New features and bug fixes to quite a few different drivers, but nothing really special standing out. What makes me happy that we have now more vendors actively contributing to upstream drivers. In this pull request we have patches from Broadcom, Intel, Qualcomm, Realtek and Redpine Signals, and I still have patches from Marvell and Quantenna pending in patchwork. Now that's something comparing to how things looked 11 years ago in Jeff Garzik's "State of the Union: Wireless" email: https://lkml.org/lkml/2006/1/5/671 Major changes: wil6210 * add low level RF sector interface via nl80211 vendor commands * add module parameter ftm_mode to load separate firmware for factory testing * support devices with different PCIe bar size * add support for PCIe D3hot in system suspend * remove ioctl interface which should not be in a wireless driver ath10k * go back to using dma_alloc_coherent() for firmware scratch memory * add per chain RSSI reporting brcmfmac * add support multi-scheduled scan * add scheduled scan support for specified BSSIDs * add support for brcm43430 revision 0 wlcore * add wil1285 compatible rsi * add RS9113 USB support iwlwifi * FW API documentation improvements (for tools and htmldoc) * continuing work for the new A000 family * bump the maximum supported FW API to 31 * improve the differentiation between 8000, 9000 and A000 families ==================== Signed-off-by: David S.

2017-06-21rsi: add tx frame for common device configurationPrameela Rani Garnepudi
After successful loading of firmware, a CARD READY indication is received by host. Common device configuration parameters are sent to the device after this. It includes information like device operating mode (Wi-Fi alone or BT coex), power save related parameters, GPIO information etc. As device supports BT coex, this frame is send in COEX queue initially. Based on the operating mode, CARD READY indication is received from each protocol module in firmware i.e. WLAN, BT.

2017-06-16networking: introduce and use skb_put_data()Johannes Berg
A common pattern with skb_put() is to just want to memcpy() some data into the new space, introduce skb_put_data() for this. An spatch similar to the one for skb_put_zero() converts many of the places using it: @@ identifier p, p2; expression len, skb, data; type t, t2; @@ ( -p = skb_put(skb, len); +p = skb_put_data(skb, data, len); | -p = (t)skb_put(skb, len); +p = skb_put_data(skb, data, len); ) ( p2 = (t2)p; -memcpy(p2, data, len); | -memcpy(p, data, len); ) @@ type t, t2; identifier p, p2; expression skb, data; @@ t *p; ...

2016-11-25rsi: Add support for 802.11dPrameela Rani Garnepudi
Transmit power level in a channel is determined based on the dfs region. To support regulatory rules dfs region should be configured to device during set channel request. Also antenna gain values are taken from the mac80211 channel parameters instead of fixed values.

2016-11-25rsi: Add support for configuring tx powerPrameela Rani Garnepudi

2016-11-25rsi: Add support to filter rx framesPrameela Rani Garnepudi

vap status * Command frame vap_capabilites is modified to use for vap add, vap delete and vap update in firmware, hence new filed vap status is added. * When interface is down this frame needs to be send with vap status delete.

2016-04-12cfg80211: remove enum ieee80211_bandJohannes Berg
This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
