      net: dsa: select NET_SWITCHDEV · 3a89eaa6
      Vivien Didelot authored
      The support for DSA Ethernet switch chips depends on TCP/IP networking,
      thus explicit that HAVE_NET_DSA depends on INET.
      
      DSA uses SWITCHDEV, thus select it instead of depending on it.

      ====================
      mlx5 4K UAR
      
      The following series of patches optimizes the usage of the UAR area which is
      contained within the BAR 0-1. Previous versions of the firmware and the driver
      assumed each system page contains a single UAR. This patch set will query the
      firmware for a new capability that if published, means that the firmware can
      support UARs of fixed 4K regardless of system page size. In the case of
      powerpc, where page size equals 64KB, this means we can utilize 16 UARs per
      system page. Since user space processes by default consume eight UARs per
      context this means that with this change a process will need a single system
      page to fulfill that requirement and in fact make use of more UARs which is
      better in terms of performance.
      
      In addition to optimizing user-space processes, we introduce an allocator
      that can be used by kernel consumers to allocate blue flame registers
      (which are areas within a UAR that are used to write doorbells). This provides
      further optimization on using the UAR area since the Ethernet driver makes
      use of a single blue flame register per system page and now it will use two
      blue flame registers per 4K.
      
      The series also makes changes to naming conventions and now the terms used in
      the driver code match the terms used in the PRM (programmers reference manual).
      Thus, what used to be called UUAR (micro UAR) is now called BFREG (blue flame
      register).
      
      In order to support compatibility between different versions of
      library/driver/firmware, the library has now means to notify the kernel driver
      that it supports the new scheme and the kernel can notify the library if it
      supports this extension. So mixed versions of libraries can run concurrently
      without any issues.

      tcp: make TCP_INFO more consistent · b369e7fd
      Eric Dumazet authored
      tcp_get_info() has to lock the socket, so lets lock it
      for an extended critical section, so that various fields
      have consistent values.
      
      This solves an annoying issue that some applications
      reported when multiple counters are updated during one
      particular rx/rx event, and TCP_INFO was called from
      another cpu.

      bpf: rename ARG_PTR_TO_STACK · 39f19ebb
      Alexei Starovoitov authored
      since ARG_PTR_TO_STACK is no longer just pointer to stack
      rename it to ARG_PTR_TO_MEM and adjust comment.
