For example in "iflib_legacy_setup" the function " taskqgroup_attach" is called with an irq value other than -1, which triggers the assert.
Now, with the assert disabled the driver seems to work and we can, e.g. get an IP with the dhcpcd0x tests. 
We haven't managed to find out what the assert is for exactly, so I don't know if that opens a can of worms.
Is this safe to do?
