2023-08-28r8169: fix ASPM-related issues on a number of systems with NIC version from ↵Heiner Kallweit
RTL8168h This effectively reverts 4b5f82f6aaef. On a number of systems ASPM L1 causes tx timeouts with RTL8168h, see referenced bug report.

2023-05-23r8169: Use a raw_spinlock_t for the register locks.Sebastian Andrzej Siewior
The driver's interrupt service routine is requested with the IRQF_NO_THREAD if MSI is available. This means that the routine is invoked in hardirq context even on PREEMPT_RT. The routine itself is relatively short and schedules a worker, performs register access and schedules NAPI. On PREEMPT_RT, scheduling NAPI from hardirq results in waking ksoftirqd for further processing so using NAPI threads with this driver is highly recommended since it NULL routes the threaded-IRQ efforts. Adding rtl_hw_aspm_clkreq_enable() to the ISR is problematic on PREEMPT_RT because the function uses spinlock_t locks which become sleeping locks on PREEMPT_RT. The locks are only used to protect register access and don't nest into other functions or locks. They are also not used for unbounded period of time. Therefore it looks okay to convert them to raw_spinlock_t. Convert the three locks which are used from the interrupt service routine to raw_spinlock_t.

The open code is defined as a helper function(tp_to_dev) on r8169_main.c, which the open code is &tp->pci_dev->dev. The helper function was added in commit 1e1205b7d3e9 ("r8169: add helper tp_to_dev"). And then later, commit f1e911d5d0df ("r8169: add basic phylib support") added r8169_phylink_handler function but it didn't use the helper function. Thus, tp_to_dev() replaces the open code.
