Subject: [PATCH net-next 0/6] r8169: disable ASPM during NAPI poll

This is a rework of ideas from Kai-Heng on how to avoid the known
ASPM issues whilst still allowing for a maximum of ASPM-related power
savings. As a prerequisite some locking is added first.

Heiner Kallweit (6):
  r8169: use spinlock to protect mac ocp register access
  r8169: use spinlock to protect access to registers Config2 and Config5
  r8169: enable cfg9346 config register access in atomic context
  r8169: prepare rtl_hw_aspm_clkreq_enable for usage in atomic context
  r8169: disable ASPM during NAPI poll
  r8169: remove ASPM restrictions now that ASPM is disabled during NAPI
    poll
