  This patchset contains performance optimizations
for the DLB2 eventdev PMD.

The port probing patch is dependent on patch 115303
"eal: make eal_parse_coremask external",
since the application can pass in a coremask to aid in
discovering the best performing port/core combinations.

The fence bypass patch uses a #define intentionally.
The performance improvement is significant, but
only customers with very specific use cases can benefit
from this. We don't want to expose a command line option
that when used incorrectly could lead to data corruption.

Depends-on: patch-115303 ("eal: make eal_parse_coremask external")

Timothy McDaniel (3):
  event/dlb2: add producer port probing optimization
  event/dlb2: add fence bypass option for producer ports
  event/dlb2: optimize credit allocations
