If there are two patches in this series, which the Subject line
implies, where is the second patch?

Is there a specific reason why it is not named RTL_FEATURE_ALDPS ?
RTL_FEATURE_EXTENDED is anything but enlightning.

This same code fragment will be repeated 3 extra times. The patch duplicates
a different fragment 3 times and the driver already repeats the disable
ALDPS sequence 3 times.
What about some factoring out frenzy ? :o)

What are you trying to achieve ?
After this patch the driver would look like:
1. disable ALDPS before setting firmware (unmodified by patch)
RTL_GIGA_MAC_VER_29 "RTL8105e"
RTL_GIGA_MAC_VER_30 "RTL8105e"
RTL_GIGA_MAC_VER_37 "RTL8402"

2. apply_firmware (unmodified by patch)

RTL_GIGA_MAC_VER_26 "RTL8168d/8111d"

RTL_GIGA_MAC_VER_39 "RTL8106e"
RTL_GIGA_MAC_VER_40 "RTL8168g/8111g"
3. enable ALDPS after firmware
RTL_GIGA_MAC_VER_34 "RTL8168evl/8111evl"
RTL_GIGA_MAC_VER_35 "RTL8168f/8111f"

RTL_GIGA_MAC_VER_39 "RTL8106e"
RTL_GIGA_MAC_VER_40 "RTL8168g/8111g"
The disable/enable ALDPS code is not trivially balanced.
Do we exactly perform the required ALDPS operations ? Nothing more,
nothing less ?

The flag is determined if the firmware is loaded. It doesn't mean to enable
ALDPS. Besides ALDPS, the firmware includes the other features about power
saving, performance, hw behavior, and so on. Thus, I think it is the extended
feature. Any suggestion?

I don't sure if the firmware code still exists and works after hibernation. I
clear the flag for safe. It would be set again after loading firmware. It is
used to make sure to enable ALDPS with firmware.

Because the different design between the giga nic and 10/100M nic, the behavior
would be different. For example, you couldn't disable the ALDPS of the giga nic
directly just like the 10/100M (8136 series) one. The giga nic would disable
ALDPS automatically when loading firmware, but the 8136 series wouldn't.
Best Regards,
Hayes
Enable ALDPS function to save power when link down. Note that the
feature should be set after the other PHY settings. And the firmware
is necessary. Don't enable it without loading the firmware.

I don't understand if you want to avoid a coding bug or a hardware problem.
The code only enables ALDPS in the hw_phy_config helpers. Said helpers are
the only places where firmware loading is requested. Loading the firmware
always set RTL_FEATURE_XYZ.
Whatever you are trying to achieve, the change in rtl8169_net_suspend
seem rather useless. Please explain.
(if you want to enforce that ALDPS does nothing when it is not called
right after firmware loading, the ALDPS enable method itself is imho the
natural place to reset the bit).

It would be nice to state these things in the commit message, namely:
- ALDPS should never be enabled for the RTL8105e
- none of the firmware-free chipsets support ALDPS
- neither do the RTL8168d/8111d

In a not too distant future somebody may try to figure if things should
be fed into one of the numerous -stable trees. He will appreciate figuring
from the comment if this commit is supposed to fix anything or if it's a
pure performance thing or whatever.
The pll_power changes could be a bugfix for instance. The ALDPS change
isn't.

Do you remember why firmware loading was introduced in the first place ?
I find it increasingly hard to believe that it does not apply here.

Within a few weeks / months there will be a new update with a new
set of completely obscure parameters. It will takes a kernel cycle or
more to be distributed.
There should be some higher level data struct that could use a mundane
"for" loop and some indirection in place of this code bloat.
It is getting out of control.

No, it won't hurt. The delay make suer there is enough time to pause ALDPS.

Enable ALDPS function to save power when link down. Note that the
feature should be set after the other PHY settings. And the firmware
is necessary. Don't enable it without loading the firmware.
None of the firmware-free chipsets support ALDPS. Neither do the
RTL8168d/8111d.
For 8136 series, make sure the ALDPS is disabled before loading the
firmware. For 8168 series, the ALDPS would be disabled automatically
when loading firmware. You must not disable it directly.

I'd appreciate to see such a statement if ALDPS can be enabled with the
RTL8105e !
You have sent ALDPS related patches for some specific chipsets. Now
would be a sensible time to check if ALDPS is correctly handled for
_all_ supported chipsets. I don't have access to your authoritative
resources. I can only outline something strange in the code wrt
ALDPS and the 8105e.
/me returns to 8169b RxOverflow oddities...

Applied, thanks.
