[dpdk-dev] [PATCH 06/10] net/enetc: cache align enetc bdr structure

[Hemant Agrawal <hemant.agrawal@nxp.com>]

From: Alex Marginean <alexandru.marginean@nxp.com>

Reorder the members of the structure so that the ones used on datapath fit
in a single cache line, to slightly reduce pressure on cache and miss rate.
