Hi all,

I have written a custom driver implementation for GRETH adapted to rtems-libbsd(branch version 5), for an RTEMS 5-based space project.
I would like to contribute it and would appreciate some guidance:
- Should I submit it as-is to get early feedback?
- Are there documentation references or examples you recommend reviewing to better align the driver with rtems-libbsd expectations?

My driver has been tested only on 10/100 Mbit mode and only on the following targets:
-     GR712RC (sparc/leon3, real hardware)
-     QEMU(sparc/leon3), with GRETH emulation that I developed specifically for this purpose(i'll try to push my commits on qemu as well ).

The driver was developed in the context of a publicly funded ESA project.
To the best of my knowledge, there are no restrictions on contributing it under the usual RTEMS/libbsd licensing.

The original driver may have some project-specific assumptions that I'd be happy to clean up if needed.

Thank you very much — I'm looking forward to contributing!
