From: Viacheslav Ovsiienko Date: Mon, 5 Aug 2019 13:03:49 +0000 (+0000) Subject: net/mlx5: fix default minimal data inline X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=614de6c898aa938b3ec8c9991bec0bfdebc31545;p=dpdk.git net/mlx5: fix default minimal data inline The patch [Fixes] sets the default value of required minimal inline data to 0 bytes. On some configurations (depends on switchdev/legacy settings and FW version/settings) the ConnectX-4LX NIC requires minimal 18 bytes of Tx descriptor inline data to operate correctly. Wrongly set to 0 default value may prevent NIC from operating with out-of-the-box settings, this patch reverts default value for ConnectX-4LX back to 18 bytes (inline L2).
