Description airremi 2016-04-14 11:39:11 UTC

The TapFdNetDeviceHelper does not seem to work in ns-3.25.

Running the fd-tap-ping example crashes with the error:

assert failed. cond="numberOfDots == 3", msg="Error, can not build an IPv4 address from an invalid string: ", file=../src/network/utils/ipv4-address.cc, line=68

This is likely due to the changeset 11754, that prevents from creating IPv4 addresses from empty strings (which is done in several places in the TapFdNetDeviceHelper).
