      ATM-iphase: Use kmalloc_array() in tx_init() · e808bb6e
      Markus Elfring authored
      * Multiplications for the size determination of memory allocations
        indicated that array data structures should be processed.
        Thus use the corresponding function "kmalloc_array".
      
        This issue was detected by using the Coccinelle software.
      
      * Replace the specification of data types by pointer dereferences
        to make the corresponding size determination a bit safer according to
        the Linux coding style convention.

      alx: add msi-x support
      
      This patchset adds msi-x support to the alx driver. It is a preparatory
      series for multi queue support, which I am currently working on. As there
      is no advantage over msi interrupts without multi queue support, msi-x
      interrupts are disabled by default. In order to test for regressions, a
      new module parameter is added to enable msi-x interrupts.
      
      Based on information of the downstream driver at github.com/qca/alx

      alx: add msi-x support · dc39a78b
      Tobias Regnery authored
      Add msi-x support to the alx driver. This is in preparation for multi queue
      support.
      
      msi-x interrupts are disabled by default because without multi queue support
      there is no advantage over msi interrupts. The performance numbers observed
      with iperf stay the same.

      alx: factor out part of the interrupt handler · a0373aef
      Tobias Regnery authored
      Factor out the handling of misc interrupts into a new function.
      This function can be reused later for msi-x interrupts.

      alx: refactor msi enablement and disablement · 9ee7b683
      Tobias Regnery authored
      Introduce a new flag field for the advanced interrupt capatibilities and add
      new functions to enable and disable msi interrupts. These functions will be
      extended later to cover msi-x interrupts.
      
      We enable msi interrupts earlier in alx_init_intr because with msi-x and multi
      queue support the number of queues must be set before we allocate resources for
      the rx and tx paths.

      In fact, these functions are only used in the file in which they are
      declared and don't need a declaration, but can be made static.
      so this patch marks these functions with 'static'.

      ====================
      Some BPF helper cleanups
      
      This series contains a couple of misc cleanups and improvements
      for BPF helpers. For details please see individual patches. We
      let this also sit for a few days with Fengguang's kbuild test
      robot, and there were no issues seen (besides one false positive,
      see last one for details).
