Subject: r8169: prevent excessive busy-waiting

The MII registers read/write function blindly busy waits for an
amount of 1000 us (1 ms), then up to 200 ms. These functions are
called from irq disabled context. Depending on the clock management,
it triggers lost ticks events. Since the value is way above the
standard delay required for mii register access, it strangely looks
like a bandaid against posted writes.

e100 seems to have had a long standing bug where e100_init_hw was being

There were bugs in mmconfig access to PCI space, up to and
include 2.6.16-rc1. These prevented the sky2 driver from being
able to clear PCI express errors.

This patch makes the driver check (during probe), for errors
in PCI config access and fail.

Subject: [PATCH] sky2: set mac address fix

Using the sky2 driver with bonding can result in oopses related to
reinitializing the PHY when the MAC address is changed (which bonding
is wont to do).  This patch changes sky2_set_mac_address to take less
drastic measures.

This is analagous to the skge patch here:

	http://lkml.org/lkml/2005/9/29/399

which fixed the issue here:

	http://bugzilla.kernel.org/show_bug.cgi?id=5271

Subject: [PATCH] Kbuild menu - hide empty NETDEVICES menu when NET is disabled

Make the whole netdevices menu depend on NET, rather than having an empty
submenu when networking is disabled.

Indeed, almost the whole body of the menu was surrounded by if NETDEVICES,
and what was outside depended on NETCONSOLE which is inside the menu.
