Subject: net/bnxt: free EM index on failure
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=f01b6fceac77d9649aed46daf231b334f6a9dc94;p=dpdk.git

net/bnxt: free EM index on failure

When a Exact Match entry fails insertion, the allocated index needs to
be pushed back to the allocation stack. This patch takes care of that.
