From: Igor Romanov Date: Fri, 2 Jul 2021 08:39:36 +0000 (+0300) Subject: common/sfc_efx/base: add user mark RxQ flag X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c414c567c76b3d8ea0bc44d4aea9749bea48dcac;p=dpdk.git common/sfc_efx/base: add user mark RxQ flag Add a flag to request support for user mark field on an RxQ. The field is required to retrieve generation count value from counter RxQ. Implement it only for Riverhead and EF10 ESSB since they support the field in the Rx prefix.
