This commit fixies two problems. The first one is interface types (e.g. PCI) that are used to switch antenna, and the second is to add wifi_only parameter to give correct state. Signed-off-by:

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. Signed-off-by:

Before firmware load, sometimes false interrupts are received. System hang is observed if interrupt handler is not registered to receive these interrupts. Hence interrupt handler registration is moved before firmware load. We will drop these false interrupts as these are not from the device. Signed-off-by:

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. Signed-off-by:

An earlier change to this function (3bdae810) fixed a leak in the case of an unsuccessful call to brcmf_sdiod_buffrw(). However, the glom_skb buffer, used for emulating a scattering read, is never used or referenced after its contents are copied into the destination buffers, and therefore always needs to be freed by the end of the function.

This change adds support for multi-scheduled scan in the driver. It currently relies on g-scan support in firmware and will set struct wiphy::max_sched_scan_reqs accordingly. This is limited to 16 concurrent requests. The firmware currently has a limit of 64 channels that can be configured for all requests in total regardless whether there are duplicates. So if a request uses 35 channels there are 29 channels left for another request. When user-space does not specify any channels cfg80211 will add all channels defined by the wiphy instance to the request, which makes reaching the limit rather easy for dual-band devices.

The former was easy but latter needed more thought. Apparently the mutex was taken too late, so I fixed so that the mutex is taken first and then check for iwl_mvm_firmware_running().

Paolo Abeni says: ==================== udp: reduce cache pressure In the most common use case, many skb fields are not used by recvmsg(), and the few ones actually accessed lays on cold cachelines, which leads to several cache miss per packet. This patch series attempts to reduce such misses with different strategies: * caching the interesting fields in the scratched space * avoid accessing at all uninteresting fields * prefetching Tested using the udp_sink program by Jesper[1] as the receiver, an h/w l4 rx hash on the ingress nic, so that the number of ingress nic rx queues hit by the udp traffic could be controlled via ethtool -L. The udp_sink program was bound to the first idle cpu, to get more stable numbers.

when udp_recvmsg() is executed, on x86_64 and other archs, most skb fields are on cold cachelines. If the skb are linear and the kernel don't need to compute the udp csum, only a handful of skb fields are required by udp_recvmsg(). Since we already use skb->dev_scratch to cache hot data, and there are 32 bits unused on 64 bit archs, use such field to cache as much data as we can, and try to prefetch on dequeue the relevant fields that are left out. This can save up to 2 cache miss per packet. v1 -> v2: - changed udp_dev_scratch fields types to u{32,16} variant, replaced bitfiled with bool Signed-off-by:Paolo Abeni <pabeni@redhat.com> Acked-by:

Since UDP no more uses sk->destructor, we can clear completely the skb head state before enqueuing. Amend and use skb_release_head_state() for that. All head states share a single cacheline, which is not normally used/accesses on dequeue. We can avoid entirely accessing such cacheline implementing and using in the UDP code a specialized skb free helper which ignores the skb head state. This saves a cacheline miss at skb deallocation time. v1 -> v2: replaced secpath_reset() with skb_release_head_state() Signed-off-by:

Saeed Mahameed says: ==================== mlx5-updates-2017-06-11 This series provides updates to mlx5 header rewrite feature, from Or Gerlitz. and three more small updates From maor and eran. ------- Or says: Packets belonging to flows which are different by matching may still need to go through the same header re-writes (e.g set the current routing hop MACs and issue TTL decrement). To minimize the number of modify header IDs, we add a cache for header re-write IDs which is keyed by the binary chain of modify header actions. The caching is supported for both eswitch and NIC use-cases, where the actual conversion of the code to use caching comes in separate patches, one per use-case. Using a per field mask field, the TC pedit action supports modifying partial fields. The last patch enables offloading that. ------- From Maor, update flow table commands layout to the latest HW spec. From Eran, ethtool connector type reporting updates. ==================== Signed-off-by:
