Any combination of (IDPF || ICE || I40E) can register auxiliary_dev, so use '||' instead of '&&' in IRDMA config.

PS: found in stable v6.12.58, it makes IRDMA be removed when select ICE+I40E+(!IDPF).
Hi Wentao,
Thank you for finding this. The Kconfig dependency change 060842fed53f ("RDMA/irdma: Update Kconfig") went in linux kernel 6.18 where RDMA IDPF support was merged.
Even though IDPF driver exists in older kernels, it doesn't provide RDMA support so there is no need for IRDMA to depend on IDPF in kernels <= 6.17.
060842fed53f ("RDMA/irdma: Update Kconfig") patch shouldn't have been backported in kernels <= 6.17 and it should be reverted.
Then the line "depends on ICE && I40E" should resolve the issue you are seeing.
