Subject: [PATCH net-next 4/9] idpf: convert to libie Tx buffer completion
From: Alexander Lobakin <aleksander.lobakin@...el.com>
&idpf_tx_buffer is almost identical to the previous generations, as well
as the way it's handled. Moreover, relying on dma_unmap_addr() and
!!buf->skb instead of explicit defining of buffer's type was never good.
Use the newly added libeth helpers to do it properly and reduce the
copy-paste around the Tx code.
