When enabling promiscuous mode on the host network interface vmnet module drops an assertion in the kernel due to fail to obtain the RTNL lock.

Created attachment 137686 [details, diff] Protect dev_set* calls with rtnl_lock/rtnl_unlock
Created attachment 137688 [details] Changed app-emulation/vmware-modules-1.0.0.17 ebuild to use the patch
Thanks very much for the patch. We're currently testing out vmware-modules-1.0.0.17-r1, which hopefully does all the spin-locking correctly, because it's based upon the vmware-any-any-update sources. You can find the latest version in the vmware overlay (accessible via layman). Please let me know if it fixes up your problems. Thanks... 5:)
