i40e: simplified init string
In a similar way to how ixgbe works, print a short one-line string showing what features and number of queues the driver and hardware has enabled at probe time. Example (wrapped for the commit message): i40e 0000:06:00.1: Features: PF-id[1] VFs: 64 VSIs: 66 QP: 32 FDir RSS ATR NTUPLE DCB Change-ID: I177bf7f93d1c4c921529c92fdf66e614f6b4f755 Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: Catherine Sullivan <catherine.sullivan@intel.com> Tested-by: Kavindya Deegala <kavindya.s.deegala@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
