Log: sfxge(4): rename API to check Rx scale and hash support Rename efx_rx_scale_support_get() to efx_rx_scale_default_support_get(), and efx_rx_hash_support_get() to efx_rx_hash_default_support_get(). All these really report is whether an exclusive RSS context was successfully acquired at efx_rx_init(). efx_rx_scale_support_get() sounds like it reports whether the device supports RSS, and whether exclusive or shared contexts are supported, but it doesn't do that. Renaming it to efx_rx_scale_default_support_get() helps to reflect that it reports what RSS support the client gets without trying to allocate RSS contexts itself. Also rename efx_rx_scale_support_t to efx_rx_scale_context_type_t, to make the enum more suitable for specifying the type of an RSS context to be allocated.
