Minor issue with this: mdio_phy_id_is_c45() returns bool, and that's not defined by default. Should I add #include <stdbool.h> or change the return type to int for maximum compatibility?

And I sure as hell am not going to compromise using a correct type just to make this usable by userspace. I think this is of dubious value, and combined with the bool complication I'm not going to apply this, sorry. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Without this, userland doing clause 45 MDIO has to duplicate the ID packing definitions. I intended to export these to userland in the first place; that's why the header already has an #ifdef __KERNEL__. I was about to get rid of the duplicate definitions in our utilities when I realised I hadn't exported them. Ben.

Then come up with a real solution to the bool issue. But note that changing the bool to an int is not a solution, neither is #include <stdbool.h> unless we can reach consensus on lkml that this is OK. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I could just move the mdio_phy_id_is_c45(), mdio_phy_id_prtad(), mdio_phy_id_devad() functions inside #ifdef __KERNEL__ since userland shouldn't need to unpack PHY IDs. Ben.
