Date: Sat, 25 Jan 2020 05:11:58 +0000 From: Saeed Mahameed <saeedm@...lanox.com> To: "David S. Miller" <davem@...emloft.net> CC: "netdev@...r.kernel.org" <netdev@...r.kernel.org>, Erez Shitrit <erezsh@...lanox.com>, Saeed Mahameed <saeedm@...lanox.com> Subject: [net-next V2 13/14] net/mlx5: DR, Handle reformat capability over sw-steering tables From: Erez Shitrit <erezsh@...lanox.com> On flow table creation, send the relevant flags according to what the FW currently supports. When FW doesn't support reformat option over SW-steering managed table, the driver shouldn't pass this.
