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.

2017-06-21Merge branch 'ipmr-ip6mr-add-Netlink-notifications-on-cache-reports'David S. Miller
Julien Gomes says: ==================== ipmr/ip6mr: add Netlink notifications on cache reports Currently, all ipmr/ip6mr cache reports are sent through the mroute/mroute6 socket only. This forces the use of a single socket for mroute programming, cache reports and, regarding ipmr, IGMP messages without Router Alert option reception. The present patches are aiming to send Netlink notifications in addition to the existing igmpmsg/mrt6msg to give user programs a way to handle cache reports in parallel with multiple sockets other than the mroute/mroute6 socket. Changes in v2: - Changed attributes naming from {IPMRA,IP6MRA}_CACHEREPORTA_* to {IPMRA,IP6MRA}_CREPORT_* - Improved packet data copy to handle non-linear packets in ipmr/ip6mr cache report Netlink notification creation - Added two rtnetlink groups with restricted-binding - Changed cache report notified groups from RTNL_{IPV4,IPV6}_MROUTE to the new restricted groups in ipmr/ip6mr Changes in v3: - Put message size calculation for {igmp,mrt6}msg_netlink_event in separate functions - Increased vif id attributes size from u8 to u32 ==================== Signed-off-by: David S.

2017-06-21brcmfmac: Use separate firmware for revision 0 of the brcm43430 chipHans de Goede
The brcm43430 chip needs different firmware files for chip revision 0 and 1. The file currently in linux-firmware is for revision 1 only. This commit makes brcmfmac request brcmfmac43430a0-sdio.bin instead of brcmfmac43430-sdio.bin for revision 0 chips. Note that the behavior for revision 1 chips is not changed, ideally those would load brcmfmac43430a1-sdio.bin, but that will break existing setups.

Second, if the peer rx-speed is configured, and if we are in 160 or 80+80 mode, and the peer rx-speed matches the max speed for 2x2 or 1x1 at 160Mhz (long guard interval), then use that info to set the peer_bw_rxnss_override appropriately. Without this, a 9984 firmware will not use 2x2 ratesets when transmitting to peer (it will be stuck at 1x1), because the firmware would not have configured the rxnss_override.

2017-06-21ath10k: use complete VHT chan width for 160MHz workaroundBen Greear
The ath10k firmware doesn't announce its VHT channel width capabilities in the vht_cap information from the "service ready event" arguments. The driver must therefore check whether the 160MHz short GI bit is set and whether the driver still doesn't set the bits for the 160/80+80 MHz capabilities. The two bits for the channel width are a two bit integer and not two separate bits which cannot be parsed without the knowledge of the other bit. Using IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160_80PLUS80MHZ (b10..) as a mask for this task doesn't make any sense. The correct mask for the VHT channel width should be used instead to make this check more readable.

2017-06-21perf/aux: Correct return code of rb_alloc_aux() if !has_aux(ev)Hendrik Brueckner
If the event for which an AUX area is about to be allocated, does not support setting up an AUX area, rb_alloc_aux() return -ENOTSUPP. This error condition is being returned unfiltered to the user space, and, for example, the perf tools fails with: failed to mmap with 524 (INTERNAL ERROR: strerror_r(524, 0x3fff497a1c8, 512)=22) This error can be easily seen with "perf record -m 128,256 -e cpu-clock". The 524 error code maps to -ENOTSUPP (in rb_alloc_aux()). The -ENOTSUPP error code shall be only used within the kernel. So the correct error code would then be -EOPNOTSUPP. With this commit, the perf tool then reports: failed to mmap with 95 (Operation not supported) which is more clear.

2017-06-20i40e: don't hold RTNL lock for the entire resetJacob Keller
We recently refactored i40e_do_reset() and its friends to be able to hold the RTNL lock only for the portions that actually need to be protected. However, a separate refactoring added several new callers of these functions during the PCIe error recovery and suspend/resume cycles. When merging the changes together, it was not noticed that we could reduce the RTNL scope by letting the reset function handle the lock itself, as previously it was not possible. Fix this by replacing these call sites to indicate that the reset function should handle its own lock. This enables multiple PFs to reset or resume simultaneously without serializing the resets via the RTNL lock. The end result is that on systems with lots of PFs and VFs the resets don't stall waiting for each other to finish. It is probable that we can also do the same for i40e_do_reset_safe, but this author did not research that change carefully enough to be confident.

2017-06-20i40e: Handle PE_CRITERR properly with IWARP enabledCatherine Sullivan
When IWARP is enabled, we weren't clearing the PE_CRITERR, just logging it and removing it from the mask. We need to do a corer to reset the PE_CRITERR register, so set the bit for that as we handle the interrupt. We should also be checking for the error against the PFINT_ICR0 register, and only need to clear it in the value getting written to PFINT_ICR0_ENA.

2017-06-20i40e: clear only cause_ena bitShannon Nelson
When disabling interrupts, we should only be clearing the CAUSE_ENA bit, not clearing the whole register. Clearing the whole register sets the NEXTQ_IDX field to 0 instead of 0x7ff which can confuse the Firmware in some reset sequences.

2017-06-20i40e: fix disabling overflow promiscuous modeAlan Brady
There exists a bug in which the driver does not correctly exit overflow promiscuous mode. This can occur if "too many" mac filters are added, putting the driver into overflow promiscuous mode, and the filters are then removed. When the failed filters are removed, the driver reports exiting overflow promiscuous mode which is correct, however traffic continues to be received as if in promiscuous mode still. The bug occurs because the conditional for toggling promiscuous mode was set to only execute when promiscuous mode was enabled and not when it was disabled as well. This patch fixes the conditional to correctly execute when promiscuous mode is toggled and not just enabled. Without this patch, the driver is unable to correctly exit overflow promiscuous mode.

Changes parsing of FW 4.33 AQ command Get CEE DCBX OPER CFG (0x0A07). Change is required because FW now creates the oper_prio_tc nibbles reversed from those in the CEE Priority Group sub-TLV. This change will only apply to FW 4.33 as future FW versions will use a different function to parse the CEE data.

2017-06-20i40e: comment that udp_port must be in host byte orderJacob Keller
The firmware expects the port number passed when setting up the UDP tunnel configuration to be in Little Endian format. The i40e_aq_add_udp_tunnel command byte swaps the value from host order to Little Endian. Since commit fe0b0cd97b4f ("i40e: send correct port number to AdminQ when enabling UDP tunnels") we've correctly sent the value in host order. Let's also add a comment to the function explaining that it must be in host order, as the port numbers are commonly stored as Big Endian values.
