[Intel-wired-lan] What to do with info log message: `e1000e: EEE TX LPI TIMER: 00000011`?

Dear David, dear Linux folks,


On several devices, like the Dell OptiPlex 3620, Linux 5.10.47 (and 
others) log the message below with info level (often during shutdown):

     e1000e: EEE TX LPI TIMER: 00000011

     $ git grep "LPI TIMER"
     drivers/net/ethernet/intel/e1000e/netdev.c:     pr_info("EEE TX LPI 
TIMER: %08X\n",


What information is that supposed to provide? For a normal user it looks 
like spam.

Could you please extend the message what to do about it? Or should it be 
made a debug message?


Kind regards,

Paul

Hello Paul,
I believe it is a simple debug print that has forgotten to remove.(more 
than seven years ago). It is comes just to inform: Low Power IDLE Entry 
Time - minimum time between low power idle entry and exit request.
You can process the patch to remove this line. (or I can do it and add 
you as "Suggested-by").
Thanks,
Sasha
