Subject: net/mlx5: remove unused hash list operations
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=a12c188b858d99ab6ba4a33b79115c578e533f00;p=dpdk.git

net/mlx5: remove unused hash list operations

In previous commits the hash list objects have been converted
to new thread safe hash list. The legacy hash list code can be
removed now.
