[PATCH] net/nfp: use Tx ring pointer write back

From: Long Wu This follows the mainline Linux kernel commit 0dcf7f500b0a (nfp: use TX ring pointer write back) by Jakub Kicinski. This will speed up Tx completions, because we avoid a read from device memory (replacing PCIe read with DMA read), and it works on CoreNIC firmware with NFDk. Signed
