[GSOC] Help regarding pc386 3c509.c file

[Vipul Nayyar]

Hello,

Thanks for the guidance. As in the case of 3c509, there is I believe only one method, that need to be added to bsp.h . But for other files, there are multiple methods for example in ckinit, that are not internally used, but I feel they definitely cannot be removed(like a method to install interrupt handler, etc). So, I hope having multiple prototypes in bsp.h from a single file should not be a problem. Right ?

Regards
Vipul Nayyar

Hello Vipur,

its good that you ask.  Actually you found a bug in the BSPs using 
3c509.c.  As Joel already said this rtems_3c509_driver_attach() is the 
main entry point of the network interface driver and can be used by 
applications to use this interface.

So lets have a look which BSP is affected:

~/git-rtems $ grep -r 3c509.c c | grep 'am:'
c/src/lib/libbsp/i386/pc386/Makefile.am:3c509_rel_SOURCES = 3c509/3c509.c

So luckily only the pc386 BSP.  You can now add the prototype to 
"c/src/lib/libbsp/i386/pc386/include/bsp.h" line 83.  Just have a look 
at the other network interface definitions.

If I delete it, then I end up deleting all other functions also. But this rtems_3c509_driver_attach() stores references to different handlers & calls them by passing a ifnet structure to if_attach(). I think it's a very important method & I don't think I should delete it.
