From: Viacheslav Ovsiienko Date: Mon, 29 Jul 2019 12:41:04 +0000 (+0000) Subject: net/mlx5: fix ConnectX-4LX minimal inline data limit X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=9f350504bb32;p=dpdk.git net/mlx5: fix ConnectX-4LX minimal inline data limit Mellanox ConnectX-4LX NIC in configurations with disabled E-Switch can operate without minimal required inline data into Tx descriptor. There was the hardcoded limit set to 18B in PMD, fixed to be no limit (0B).
