2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: David Brownell commit 29bac7b7661bbbdbbd32bc1e6cedca22f260da7f upstream Bugfix for the new CDC Ethernet code: as part of activating the network interface's USB link, make sure its link management code knows whether the interface is open or not. Without this fix, the link won't work right when it's brought up before the link is active ... because the initial notification it sends will have the wrong link state (down, not up). Makes it hard to bridge these links (on the host side), among other things.
