The LAN9118 driver uses memory fences in a novel but erroneous fashion, due to a misunderstanding of some under-commented code. This series fixes these erroneous uses, documenting the unusual requirements of the LAN9118 chip that lead us to this situation, and introduces new helpers to handle this in a more consistent fashion.
