USB reverse tethering fails under OS X Yosemite 10.10.5

[ateamlunchbox]

Awesome piece of code here. Using release 7 of HoRNDIS, I have a Nexus 4 with Cyanogenmod (Android 4.4.4) successfully configured in a "USB reverse-tether" configuration so my USB-connected phone gets network access through the wifi on a MacBook running OS X Mavericks (10.9.5).

I tried the same USB reverse-tether configuration on a MacBook Pro running 10.10.5 and release 7, but have been unable to replicate the success I had with OS X 10.9.5. In Console.app on the 10.10.5 machine I see:

If I try to do a "normal" tether from the laptop through the phone, that seems to work fine: the "Nexus 4" shows up as "Connected" in the Network preference pane and I can ping from the phone to the laptop and back. Only when I then go to the Sharing preference pane and try to enable "Internet Sharing" from "Wi-Fi" to "Nexus 4" do things go south.

I was following http://www.androidjunkies.com/how-to-use-internet-via-usb-reverse-tethering-linux-and-mac-ver/ and when I run "netcfg usb0 dhcp" it eventually times out. I tried manually setting the usb0 interface on the phone to 192.168.2.2 (along with a default route) but still couldn't ping through.

Has anyone else encountered this behavior?
