2015-03-30ath10k: update station countingMarek Puzyniak1-10/+10
Currently station counting functions (inc_num_stations/dec_num_stations) does not handle tdls type of stations. Tdls station should be counted because it consumes peer in firmware. Only not tdls stations are excluded from this counting. Signed-off-by: Marek Puzyniak <marek.puzyniak@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2015-03-30ath10k: clear htt.freqMichal Kazior1-0/+1
If htt.freq isn't cleared and contains garbage fw may discard tx packets. Prevent this from happening by clearing htt.freq properly. Possible manifestation of the problem could be not being able to send auth request/response frames on firmware with HTT >= 3.4 (when freq param was introduced), e.g. on qca6174.

2015-03-30ath10k: fix HTT op backwards compatibility for QCA6174Kalle Valo2-1/+24
Commit 8348db298496 ("ath10k: add ATH10K_FW_IE_HTT_OP_VERSION") broke QCA6174 receive side as the HTT ids from ATH10K_FW_HTT_OP_VERSION_MAIN don't have HTT_TLV_T2H_MSG_TYPE_RX_IN_ORD_PADDR_IND set. Fix this by adding a backwards compatibility code which sets HTT op version if it's not set by the firmware image.

2015-03-30cfg80211: pass name_assign_type to rdev_add_virtual_intf()Tom Gundersen3-4/+7
This will expose in /sys whether the ifname of a device is set by userspace or generated by the kernel. The latter kind (wlanX, etc) is not deterministic, so userspace needs to rename these devices to names that are guaranteed to stay the same between reboots. The former, however should never be renamed, so userspace needs to be able to reliably tell the difference.

2015-03-30ath10k: bump up FW API to 5Kalle Valo3-0/+11
Firmware 10.2.4.48-3 now supports management frames over HTT feature and has ATH10K_FW_FEATURE_HAS_WMI_MGMT_TX. But as 10.2.4 branch has conflicting HTT ids patch "ath10k: add ATH10K_FW_IE_HTT_OP_VERSION" is needed to fix the issue. Older ath10k versions don't have support that support and to maintain backwards compatibility we need bump up the FW API to 5 not break older versions.

2015-03-30ath10k: add ATH10K_FW_IE_HTT_OP_VERSIONRajkumar Manoharan5-33/+245
Target to host HTT messages are conflicting between 10.x and other firmware revisions. By maintaining separate HTT T2H tables for each firmware revisions (main, 10x and tlv) similar to WMI abstraction, solves the conflicts. Add ATH10K_FW_IE_HTT_OP_VERSION so that the firmware can advertise the HTT interface to ath10k. This fix is needed to get management frames over HTT (ie. ATH10K_FW_FEATURE_HAS_WMI_MGMT_TX disabled) working with 10.2.4.48-2 firmware. Otherwise there will be unknown htt events and nothing works: [30087.438343] ath10k_pci 0000:02:00.0: htt event (19) not handled [30087.448691] ath10k_pci 0000:02:00.0: htt event (19) not handled [30149.032974] ath10k_pci 0000:02:00.0: htt event (19) not handled If the firmware does not have ATH10K_FW_IE_HTT_OP_VERSION use the main HTT interface. That way old firmware images will still work.

2015-03-23ath10k: move driver state check before setting throttleRajkumar Manoharan1-9/+4
Since thermal daemon is unaware of the device state, it might try to adjust the throttle state when the device is powered down. So the driver caches the value and will configure it while powering up the target. The cached value will be programed later once the device is brought up. In such case, returning error status is confusing and misleading the user application. Hence moving the driver state check before sending wmi command to target.

2015-03-20wil6210: Align Rx frames on 4*n+2 by having SNAPVladimir Kondratiev4-3/+33
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>
