From 3c2192863f2dfc64384a6c201dcf96a887367b30 Mon Sep 17 00:00:00 2001 From: Bogdan Purcareata Date: Sun, 29 Oct 2017 08:20:41 +0000 Subject: staging: fsl-dpaa2/eth: Don't account SWA in tx_data_offset When configuring the Tx buffer layout, the software annotation size is mentioned, and MC accounts for it when configuring the frame tx_data_offset. No need to handle it in the driver as well. This results in 64B less memory allocated per frame.
