[Intel-wired-lan] [PATCH iwl-net v2 0/2] e1000e: avoid unexpected autonomous power-gating on Panther Lake devices

[Vitaly Lifshits]

Panther Lake systems introduced an autonomous power gating feature for the
integrated Gigabit Ethernet in shutdown (S5) state. As part of it, the
reset value of DPG_EN bit was changed to 1. Clear this bit after
performing hardware reset, to avoid errors such as Tx/Rx hangs, or packet
loss/corruption.

This patch requires introducing a new board type for separating Panther
Lake and later devices from earlier ones.
