The feature will resume CQ scheduling + when the number of pending completions fall below a configured + threshold. + +* **Introduced dynamic HL (History List) feature for DLB device.** + + * Users can configure history list entries dynamically by passing + parameters ``use_default_hl`` and ``alloc_hl_entries``. + + * When 'use_default_hl = 1', Per port HL is set to + DLB2_FIXED_CQ_HL_SIZE (32) and command line parameter + alloc_hl_entries is ignored. + + * When 'use_default_hl = 0', Per LDB port HL = 2 * CQ depth and per + port HL is set to 2 * DLB2_FIXED_CQ_HL_SIZE. + +* **DLB credit handling scenario improvements.** + + * When ports hold on to credits but can't release them due to insufficient + accumulation (less than 2 * credit quanta) deadlocks may occur. + Improvement made for worker ports to release all accumulated credits when + back-to-back zero poll count reaches preset threshold and producer ports + release all accumulated credits if enqueue fails for a consecutive number + of retries. + + * New meson options are provided for handling credits. Valid options + are ``bypass_fence``, ``hw_credits_checks``, ``sw_credits_checks`` and + ``type_check``. These options need to be provided in meson in comma + separated form.
