Subject: bus/fslmc: remove unused funcs and align names in QBMAN
X-Git-Tag: spdx-start~1769
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=69293c7762a0dbb3c28f5e93be00aaa49b52cb48;p=dpdk.git

bus/fslmc: remove unused funcs and align names in QBMAN

name alignment for check command and result functions
putting them as separate functions instead of changing the original
functions.
