      Bluetooth: Fix reporting incorrect EIR in device found mgmt event · 6818375e
      Szymon Janc authored
      Some remote devices (ie Gigaset G-Tag) misbehave with ADV data length.
      This can lead to incorrect EIR format in device found event when
      ADV_DATA and SCAN_RSP are merged (terminator field before SCAN_RSP
      part).
      
      Fix this by inspecting ADV_DATA and correct its length if terminator
      is found.

      Note "Data length: 30" in ADV_DATA which results in 9 extra zero bytes
      after Battery Service UUID. Terminator field present in the middle of
      EIR in Device Found event resulted in userspace stop parsing EIR and
      skipping device name.

      sch_dsmark: improve memory locality · 47bbbb30
      Eric Dumazet authored
      Memory placement in sch_dsmark is silly : Better place mask/value
      in the same cache line.
      
      Also, we can embed small arrays in the first cache line and
      remove a potential cache miss.

      net: bcmgenet: Implement RX coalescing control knobs · 4a29645b
      Florian Fainelli authored
      Add support for the ethtool rx-frames coalescing parameter which allows
      defining the number of RX interrupts per frames received. The RDMA
      engine supports a configurable timeout with a resolution of
      approximately 8.192 us.
      
      We can no longer enable the BDONE/PDONE interrupts as those would
      fire for each packet/buffer received, which would defeat the MBDONE
      interrupt purpose. The MBDONE interrupt is guaranteed to correspond to a
      PDONE/BDONE interrupt when the threshold is set to 1.
