      net: fec: ptp: correct the ENET_ATCOR value · 34270f5f
      Fugang Duan authored
      The current driver adjust freq formula is:
      fe * diff = ppb * pc
      Note:
        fe: ENET ref clock frequency in Hz
        diff = inc_corr - inc: difference between default increment and correction increment
        ppb: parts per billion adjustment from base
        pc: correction period (in number of fe clock cycles)
      
      The correction increment will be used after N cycles of regular increments,
      not every N cycles (with N being the correction period). For example, set ENET_ATCOR=4,
      INC=8, INC_CORR=9, there will be 4 increments of 8 (ENET_ATINC[INC]) , followed by 1
      increment of 9 (ENET_ATINC[INC_CORR]).
      
      So, the correct formula is:
      	fe * diff = ppb * (pc + 1)
      
      For ENET_ATCOR, a value 0 disables the correction counter and no corrections occur.
      So base on the origin formula, set pc = pc > 1 ? pc - 1 : pc.

      tcp: get_cookie_sock() consolidation · b80c0e78
      Eric Dumazet authored
      IPv4 and IPv6 share same implementation of get_cookie_sock(),
      and there is no point inlining it.
      
      We add tcp_ prefix to the common helper name and export it.

      net: bcmgenet: improve TX timeout · 13ea6578
      Florian Fainelli authored
      Dump useful ring statistics along with interrupt status, software
      maintained pointers and hardware registers to help troubleshoot TX queue
      stalls.
      
      When a timeout occurs, disable TX NAPI for the rings, dump their states
      while interrupts are disabled, re-enable interrupts, NAPI and queue flow
      control to help with the recovery.
