From: Qi Zhang Date: Thu, 29 Aug 2019 02:36:28 +0000 (+0800) Subject: net/ice/base: add function to configure Tx AQ command X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d1880ece7d116fe88fbe97ae49697a73f1973ae3;p=dpdk.git net/ice/base: add function to configure Tx AQ command This function is needed by the driver to move PSM leaf nodes to a new parent. Additionally, add struct ice_aqc_move_txqs to struct ice_aq_desc so driver code can access it.
