The build failures in CentOS 7, Ubuntu 18.04 and in OpenSUSE Leap 15.2 no longer reproduce. But we just noticed that Ubuntu 16.04.7 (gcc 5.4.0) is also failing with a different error:

"""
drivers/net/ice/ice_rxtx_vec_avx512.c:1:0: error: bad value (skylake-avx512) for -march= switch
 /* SPDX-License-Identifier: BSD-3-Clause
"""
Which is also caused by "net/ice: add AVX512 vector path".

Regards,
Ali
