expression: Set range expression 'len' field
|
|
|
|
The length value is needed for netlink debug output of concatenated
|
|
ranges. Set it to one of the inner elements' lengths (which should be
|
|
identical).
|
|
|
|
Since the inner element length may not be set initially, set it in
|
|
eval phase again. This covers at least all cases in tests/py.
|
|
|
|
Without this, netlink_gen_concat_key() et al. would have to inspect
|
|
element types and extract lengths accordingly, this is much easier.
