[v8,20/23] event/dlb2: add PMD's token pop public interface
Checks
Commit Message
The PMD uses a public interface to allow applications to
control the token pop mode. Supported token pop modes are
as follows, and they impact core scheduling affinity for
ldb ports.
AUTO_POP: Pop the CQ tokens immediately after dequeueing.
DELAYED_POP: Pop CQ tokens after (dequeue_depth - 1) events
are released. Supported on load-balanced ports
only.
DEFERRED_POP: Pop the CQ tokens during next dequeue operation.

This comment applies to the dlb series too:
Those lines should be aligned with spaces, not tabs.
And the crypto_scheduler line is missing a comma.

Fixed in local repos for both DLB and DLB2. Will be included in next rev of patch-sets.

I have made the requested changes to doc/api/doxy-api-index.md in DLB and DLB2 repos, but I still see this error:
/home/travis/build/ovsrobot/dpdk/doc/api/doxy-api-index.md:54: error: unable to resolve reference to `rte_pmd_dlb.h' for \ref command (warning treated as error, aborting
I was hoping that the formatting issues were the culprit, but apparently not. Any thoughts?
Thanks,
Tim

You must instruct where to find this header via doxy-api.conf.in
