As part of support for E810 XXV devices, some device ids were inadvertently left out. Add those missing ids. Fixes: 195fb97766da ("ice: add additional E810 device id") Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> Acked-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Acked-by: Paul Menzel <pmenzel@molgen.mpg.de>
