str2sa_range() already allows the caller to provide <proto> in order to
get a pointer on the protocol matching with the string input thanks to
5fc9328a ("MINOR: tools: make str2sa_range() directly return the protocol")
However, as stated into the commit message, there is a trick:
"we can fail to return a protocol in case the caller
accepts an fqdn for use later. This is what servers do and in this
case it is valid to return no protocol"
In this case, we're unable to return protocol because the protocol lookup
depends on both the [proto type + xprt type] and the [family type] to be
known.
While family type might not be directly resolved when fqdn is involved
(because family type might be discovered using DNS queries), proto type
and xprt type are already known. As such, the caller might be interested
in knowing those address related hints even if the address family type is
not yet resolved and thus the matching protocol cannot be looked up.
Thus in this patch we add the optional net_addr_type (custom type)
argument to str2sa_range to enable the caller to check the protocol type
and transport type when the function succeeds.
