From 05fa39c6b93fd859cd768a48a1d9615edcff0a94 Mon Sep 17 00:00:00 2001 From: Ioana Radulescu Date: Tue, 6 Jun 2017 10:00:37 -0500 Subject: [PATCH] staging: fsl-dpaa2/eth: Only store bpid in priv struct We only need to know the buffer pool id, so save exactly that in the device's private structure, instead of the entire DPBP attributes struct.
