selecting a tristate

Hello,

I wrote a network driver that needs CONFIG_CRC32, so I have:

	config NS9XXX_ETH
		tristate "..."
		depends on PHYLIB
		select CRC32

Currently if I choose CONFIG_NS9XXX_ETH=m I get CONFIG_CRC32=y. I would prefer to only get CONFIG_CRC32>=CONFIG_NS9XXX_ETH. I tried to implement it, but I did't find a way to do so.

Is this idea sensible? Do you know any breakage this would introduce?

AFAIK "depends on" works this way. That is if CONFIG_PHYLIB=m above I cannot select NS9XXX_ETH=y.

Best regards
Uwe
