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.
