[SRU][L][PATCH 0/4] Ethernet not stable 23.04 (RTL8168/8169) (LP: #2031537)

[Juerg Haefliger]

[Impact]

Ethernet is unstable with Realtek RTL8168h/8111h NIC and kernel 6.2 resulting in frequent transmit queue timeouts. Related to ASPM. See 'original description' below.

[Test Case]

Just regular usage for an extended period of time. No transmit queue timeouts with RTL8168h/8111h NICs.

[Where Problems Could Occur]

Modification are isolated to the r8169 driver so only machine where that driver is loaded are affected. Issues could show up as kernel crashes, stack traces, non-fnuctional wired network.


Heiner Kallweit (4):
  r8169: fix ASPM-related problem for chip version 42 and 43
  r8169: revert 2ab19de62d67 ("r8169: remove ASPM restrictions now that
    ASPM is disabled during NAPI poll")
  Revert "r8169: disable ASPM during NAPI poll"
  r8169: fix ASPM-related issues on a number of systems with NIC version
    from RTL8168h
