[PATCH net-next v4 0/2] net: stmmac: Disable EEE on i.MX

[Laurent Pinchart <laurent.pinchart@ideasonboard.com>]

Hello,

This small patch series fixes a long-standing interrupt storm issue with
stmmac on NXP i.MX platforms.

The initial attempt to fix^Wwork around the problem in DT ([1]) was
painfully but rightfully rejected by Russell, who helped me investigate
the issue in depth. It turned out that the root cause is a mistake in
how interrupts are wired in the SoC, a hardware bug that has been
replicated in all i.MX SoCs that integrate an stmmac. The only viable
solution is to disable EEE on those devices.

Individual patches explain the issue in more details. Patch 1/2,
authored by Russell, adds a new STMMAC_FLAG to disable EEE, and patch
2/2 sets the flag for i.MX platforms.
