OK, how about adding a CONFIG_MACB_ADVERTISE(id)-option, where id is
the id of the MACB (passed to the macb_eth_initialize-function). This
makes it possible to add this without touching anything but the
macb-driver (i.e. without changing the macb_eth_initialize-prototype).
In the config-files, one could then have:
#define CONFIG_MACB_ADVERTISE(id) ( \
(id == 0) ? ( \
ADVERTISE_ALL | ADVERTISE_CSMA \
) : ( \
ADVERTISE_CSMA | ADVERTISE_10HALF | \
ADVERTISE_10FULL \
))
Or in the simple (and probably mose usual case (only one set of options
advertised):
#define CONFIG_MACB_ADVERTISE(id) ( \
(ADVERTISE_CSMA | ADVERTISE_10HALF | ADVERTISE_10FULL)
This would require saving the id to the macb_device struct. If this is
unacceptable, it could be changed to using the regs-offset instead of
the id.
Any thoughts about this?
Best regards,
