set_elem: Introduce support for NFTNL_SET_ELEM_KEY_END
|
|
|
6ed431 |
|
|
|
6ed431 |
The new set element attribute maps to the netlink attribute
|
|
|
6ed431 |
NFTA_SET_ELEM_KEY_END in the same way as NFTNL_SET_ELEM_KEY
|
|
|
6ed431 |
maps to NFTA_SET_ELEM_KEY, and represents the key data used
|
|
|
6ed431 |
to express the upper bound of a range, in concatenations.
