Currently we set the default number of Tx and Rx descriptors to 128 by default. For Rx this amounts to a full page (assuming 4K pages) because each Rx descriptor is 32 Bytes, but for Tx it only amounts to a half page because each Tx descriptor is 16 Bytes (assuming 4K pages). Instead of assuming 4K pages, determine the ring size and the number of descriptors for Tx and Rx based on a calculation using the PAGE_SIZE, ICE_MAX_NUM_DESC, and ICE_REQ_DESC_MULTIPLE. This change is being made to improve the performance of the driver when using the default settings.
