[PATCH 1/8] staging: et131x: Remove TODO entry 'alloc_etherdev initilising memory with zero'

[Mark Einon]

Removing this as I'm pretty sure its not true, and alloc_etherdev isn't provided by this driver anyway. Alternatively, its a badly written comment and I don't understand it.

This drivers use of alloc_etherdev() is within keeping with other net devices, so I'm happy.

[PATCH 2/8] staging: et131x: Introduce et1310_in_phy_coma() call

[Mark Einon]

In several places in the code, the pm_csr register is read and the PHY_SW_COMA bit checked.

Move this check into its own small function to make the code more readable.

[PATCH 3/8] staging: et131x: Remove adapter->bmsr, replace with phydev equivalents

[Mark Einon]

adapter->bmsr is no longer being updated, but is also used to check the link state in places.

Remove bmsr from adapter, and replace link state checks with phydev->link check.

[PATCH 5/8] staging: et131x: Fix add_timer() from et131x_open

[Mark Einon]

The error_timer was only getting initialised and an initial jiffies value set following a probe.
This could result in the timer needlessly expiring immediately after et131x_open is called.
Now this is all done from the open call instead.

[PATCH 8/8] staging: et131x: Fix indefinite low power sleep

[Mark Einon]

The mechanism by which the device is put into low power sleep is broken
in that the device can never come back out of low power mode afterwards.
Temorary fix to bring the device back out of sleep almost immediately,
until a suitable wake trigger can be found.

You can/should split et131x_{open/close} to remove this failure point.

There is not much driver specific there. It should probably go through
pci_driver.driver.pm.

Something like:

int et131x_open(struct net_device *netdev)
{
	add_timer(...)

	err = request_irq(...)
	if (err < 0)
		goto release_timer;

	et131x_start(...)

out:
	return err;

release_timer:
	blah;
	goto out;
}

Same thing with et131x_close / et131x_stop. You only use et131x_{start/stop}
for suspend/resume : one error path is gone away.

Both DRIVER_AUTHOR and DRIVER_AUTHOR2 are silly macros.  Put the name
in directly.  That way you won't need the comment explaining where to
find the definitions.  Also normally people use gt lt brackets for
emails:

MODULE_AUTHOR("Victor Soriano <vjsoriano@agere.com>");
MODULE_AUTHOR("Mark Einon <mark.einon@gmail.com>");

Go ahead and fix this in a later patch if you want.  All the macros
there should probably be replaced.

Btw, the problems with kernel.org have complicated things here, so
I can't tell if you have already fixed this, but the driver doesn't
compile any more.  The Kconfig file says it "depends on NETDEV_1000"
but NETDEV_1000 isn't around any more since f860b0522f65d3
"drivers/net: Kconfig and Makefile cleanup" was merged.

Hi Dan, thanks for the feedback.Removing et131x_version.h file and
simplifying the macros is alreadyon my todo list.

No, I've not experienced this issue yet. I'm using Greg's
staging-2.6tree, last updated at 7cbf3c7cd59 which doesn't have the
commit youmention.I'll look out for it when everything gets moving
again.
Cheers,
