From: Ori Kam Date: Thu, 18 Apr 2019 13:16:06 +0000 (+0000) Subject: net/mlx5: add Forward Database table type X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=a567a5b683fddb2c24b6af4c84a137437294f953;p=dpdk.git net/mlx5: add Forward Database table type Actions like encap/decap, modify header require setting the flow table type. Until now we supported only Nic RX and Nic TX, this commits adds the support for FDB table type for those actions.
