From: Ajit Khaparde Date: Wed, 12 May 2021 07:58:07 +0000 (-0700) Subject: net/bnxt: support runtime queue setup X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=0105ea1296c91d9c2ff4ba5a13992566d7c3fc84;p=dpdk.git net/bnxt: support runtime queue setup Add support for runtime Rx and Tx queue setup. This will allow Rx/Tx queue setup after the interface is started.
