Subject: net/ice/base: check RSS flow profile list
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=171a4ae26d14ae308729cf0c5beda396ea46b3af;p=dpdk.git

net/ice/base: check RSS flow profile list

Minor change to check if there are any RSS flow profiles to remove.
This will avoid flow profile lock acquisition and release
if the list is empty.
