[dpdk-dev] [PATCH v2 03/16] bus/fslmc: combine thread specific variables

[Hemant Agrawal]

From: Gagandeep Singh <g.singh at nxp.com>

This is to reduce the thread local storage.
Note that though these variables are part of *.map file
but they are internal to tbe fslmc and dpaa2 drivers and not exposed
outside.
