WARNING when using send() to send via pppoe interface

[stark131]

Brief description

Scapy ver: 2.5.0

Issue description: I created a packet with the simple following elements:

ip=IP(dst=dst_ip,version=4) ### the dst_ip looks like "1.1.1.1", which is a valid IPv4 address. 
pac=ip/tcpdata/Raw(load=data)
pac.show()
send(ip,verbose=1)

When I try to call send() to an address that goes through the Ethernet interface, it was all fine. However, when I try to call send() to an address that goes through the pppoe interface, this warning comes up:

WARNING: Incompatible L3 types detected using <class 'scapy.layers.inet.IP'> instead of <class 'scapy.layers.inet6.IPv46'> !

I am not sure if this is bug or feature but I am pretty sure that the packet is created properly.
