You could enhance the structures in ip_addr.h to store the information
received. The way SER uses UDP sockets would force you to do
setsockopt() quite often, though.
SER already allows you to set a resonable global default (i.e. tos=104)
in ser.cfg which is used for all outbound messages.

Just out of curiosity: What's your application? Do you need different
TOS values on different 'routes'?
