[ Upstream commit 61343e6da7810de81d6b826698946ae4f9070819 ]
When FEC mode was changed the link didn't know it because the link was not reset and new parameters were not negotiated. Set a flag 'I40E_AQ_PHY_ENABLE_ATOMIC_LINK' in 'abilities' to restart the link and make it run with the new settings.
