This is what we have in lib/meta-flow.h:
/* "recirc_id".
*
* ID for recirculation. The value 0 is reserved for initially received
* packets. Internal use only, not programmable from controller.
*
* Type: be32.
* Maskable: no.
* Formatting: decimal.
* Prerequisites: none.
* Access: read-only.
* NXM: NXM_NX_RECIRC_ID(36) since v2.2.
* OXM: none.
*/
The current strategy for recirc-id allocation is to get the next free one,
which is essentially unsuitable for masking.
If we want to make a future change to maskable easier, then that is a different
issue
