be2net: Use Kconfig flag to support for enabling/disabling adapters
Add flags to enable/disable supported chips in be2net. With disable support are removed coresponding PCI IDs and also codepaths with [BE2|BE3|BEx|lancer|skyhawk]_chip checks. Disable chip will reduce module size by: BE2 ~2kb BE3 ~3kb Lancer ~10kb Skyhawk ~9kb When enable skyhawk only it will reduce module size by ~20kb New help style in Kconfig Reviewed-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: Petr Oros <poros@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
