[PATCH 1/7] sky2: add Wake On Lan support

[Stephen Hemminger]

[-- Attachment #1: sky2-wol2.patch --]
[-- Type: text/plain, Size: 12348 bytes --]

Adds basic magic packet wake on lan support to the sky2 driver.
Note: initial WOL value is based on BIOS settings.

[PATCH 2/7] sky2: use dev_err for error reports

[Stephen Hemminger]

[-- Attachment #1: sky2-dev-printk.patch --]
[-- Type: text/plain, Size: 6641 bytes --]

Use the standard dev_xxx functions instead of printk directly for
error reports. Fix a bug where the initialization would return 0
if allocation of network device failed.

[PATCH 3/7] sky2: TSO support for EC_U

[Stephen Hemminger]

[-- Attachment #1: sky2-ec-u-tso.patch --]
[-- Type: text/plain, Size: 1170 bytes --]

The Yukon EC_U chipset apparently supports TSO but only for non-Jumbo
frame sizes because it lacks a Ram buffer.

[PATCH 4/7] sky2: safer transmit timeout

[Stephen Hemminger]

[-- Attachment #1: sky2-tx-reset.patch --]
[-- Type: text/plain, Size: 2713 bytes --]

Rather than trying to be "smart" about possible transmit timeout
causes. Just clear all pending frames and reset the PHY.

[PATCH 5/7] sky2: Yukon Extreme support

[-- Type: text/plain, Size: 8491 bytes --]

This is basic support for the new Yukon Extreme
chip, extracted from the new vendor driver 10.0.4.3.

Since this is untested hardware, it has a big fat warning for now.

Any objection against the use of :

static bool is_yukon_extreme(struct sky2_hw *hw)
{
	return hw->chip_id == CHIP_ID_YUKON_XL ||
		hw->chip_id == CHIP_ID_YUKON_EC_U ||
		hw->chip_id == CHIP_ID_YUKON_EX;
}

?

These chips aren't "extreme", it might be easier to turn the
test around and test for the chips that aren't that way.
