Please verify this assumption:

I should not do any processing on the bytes of an IPv4 address because
regardless of endianity it is always interpreted as a guint8[4] where
[0] contains the first byte. so that would always be
stored regardless of the endianity as 0a:0b:0c:0d.

Is that correct?
At least for IPv4 addresses handed to SET_ADDRESS() or 
proto_tree_add_ipv4(), yes, the IPv4 address should be a sequence of 4 
bytes in network byte order, so that the first byte (byte[0]) is the 
topmost byte of the address.
ip_to_str()/ip_to_str_buf(), etc. also expect the address to be in that 
format.  At least as I read the inet_nto* man pages, so do inet_ntoa, 
inet_ntop, etc..
