Hi Rob There was a bit of discussion about this with the RFC patches. The bit stream protocol used here is not that used by SMI in MDIO. It is something proprietary to Realtek. I don't expect we will be re-using the code with other vendors. The only real reason to abstract this out is if there happens to be other Realtek switches which uses the same SMI bitstream, but have completely different registers, meaning a separate DSA driver would be needed. The SMI code is well structured, so it should not be too hard to turn it into a library which drivers can share. So i personally don't see a problem with this.
