Subject: [PATCH net-next 09/15] i40e: Initialize hardware capabilities at single place
From: Ivan Vecera <ivecera@...hat.com>
Some i40e_hw.caps bits are set in i40e_set_hw_caps(), some of them
in i40e_init_adminq() and the rest of them in i40e_sw_init().
Consolidate the initialization to single proper place i40e_set_hw_caps().
