From 8c8eea07c1fd46455b3a275a03c27326ddc42b20 Mon Sep 17 00:00:00 2001 From: Raed Salem Date: Wed, 23 Oct 2019 16:03:12 +0300 Subject: net/mlx5: Use the correct IPsec capability function for FPGA ops Currently the IPsec acceleration capability function is also used at IPsec fpga capable device code. This could cause a future bug as the acceleration layer is agnostic to the device implementing its API. Fix by using the IPsec FPGA capability function instead of acceleration layer capability function in case of FPGA IPsec only related operations. Downstream patches will add support for Connect-X IPsec, this can avoid a future bug.
