tap: Pass source address to protocol handler functions

Browse Source 
The tap code passes the IPv4 or IPv6 destination address of packets it
receives to the protocol specific code.  Currently that protocol code
doesn't use the source address, but we want it to in future.  So, in
preparation, pass the IPv4/IPv6 source address of tap packets to those
functions as well.
