intervals: Convert byte order implicitly
|
|
|
|
When converting ranges to intervals, the latter's high and low values
|
|
must be in network byte order. Instead of creating the low/high constant
|
|
expressions with host byte order and converting the value, create them
|
|
with Big Endian and keep the value as is. Upon export, Little Endian MPZ
|
|
values will be byte-swapped by mpz_export_data() if BYTEORDER_BIG_ENDIAN
|
|
is passed.
|
|
|
|
The benefit of this is that value's byteorder may be communicated to
|
|
libnftnl later by looking at struct expr::byteorder field. By the time
|
|
this information is required during netlink serialization, there is no
|
|
other indicator for data byte order available.
