2015-08-06wil6210: allow to handle Rx on 2 coresVladimir Shulman
Allow network stack part of Rx processing to run on separate core, relaxing CPU utilization on the core used for Rx NAPI. If RXHASH feature is enabled, the driver sets rxhash of each skb to 1 to enable RPS. The core for processing the rx skb is determined by RPS mechanism according to rx_cpus bit mask which is configured at user level. For processing skbs on different core from the core which processes the interrupts, it is recommended not to enable core 0 in rx_cpus bit mask.

Replace macros like "R", "W", "S", "C", defined multiple times, with inline functions "wil_[rwsc]". Use "readl" and "writel" instead of "ioread32" and "iowrite32" since it is granted that memory transactions are used, not port ones like IN/OUT Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2015-08-06wil6210: remove 3-MSI supportVladimir Kondratiev
In the recent kernel versions, multiple MSI is not well supported. In particular, it is not supported on x86 and ARM architectures. Also, internal interrupt handling logic is simpler and more effective when using single interrupt. Remove support for 3 MSI, convert module parameter "use_msi" from int with range [0,1,3] to boolean.

2015-05-26cfg80211: properly send NL80211_ATTR_DISCONNECTED_BY_AP in disconnectJohannes Berg
When we disconnect from the AP, drivers call cfg80211_disconnect(). This doesn't know whether the disconnection was initiated locally or by the AP though, which can cause problems with the supplicant, for example with WPS. This issue obviously doesn't show up with any mac80211 based driver since mac80211 doesn't call this function. Fix this by requiring drivers to indicate whether the disconnect is locally generated or not. I've tried to update the drivers, but may not have gotten the values correct, and some drivers may currently not be able to report correct values. In case of doubt I left it at false, which is the current behaviour. For libertas, make adjustments as indicated by Dan Williams.

2015-03-20wil6210: Align Rx frames on 4*n+2 by having SNAPVladimir Kondratiev
For the networking code and for hardware network accelerators, it is better to have IP header 4*n aligned. On the other side, DMA on Rx path require buffer to be aligned on 4*n as well. Having 14 bytes of Ethernet header, these 2 alignment requests are in contradiction. To solve this, order hardware offload block to not remove SNAP header. This adds extra 6 bytes between addresses and ethertype, making it 20 bytes total. This way, both buffer and IP header are 4*n aligned. Remaining is only to remove SNAP by shifting addresses 6 bytes. This involves data copying, so this feature should be disabled unless required by the platform. Module parameter "rx_align_2" (bool, default - false) introduced to control this feature. Feature is completely disabled when parameter is false. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
