netlink_delinearize: fix decoding of concat data element
|
|
|
|
Its possible to use update as follows:
|
|
|
|
meta l4proto tcp update @pinned { ip saddr . ct original proto-src : ip daddr . ct original proto-dst }
|
|
|
|
... but when listing, only the first element of the concatenation is
|
|
shown.
|
|
|
|
Check if the element size is too small and parse subsequent registers as
|
|
well.
