It shouldn't be sending a "connect" event on the ethernet device if the network really isn't present. How about getting it fixed there, which will resolve the issues for all guest operating systems, not just Linux. Or, if this is something that the hyperv developers are not going to fix, we need to document it in the code itself so that people don't try to remove it in a few years as an "optimization". thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
