Subject[PATCH 4.14 035/183] i40iw: Free IEQ resources
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mustafa Ismail <mustafa.ismail@intel.com>


[ Upstream commit f20d429511affab6a2a9129f46042f43e6ffe396 ]

The iWARP Exception Queue (IEQ) resources are not freed when a QP is
destroyed. Fix this by freeing IEQ resources when freeing QP resources.

Fixes: d37498417947 ("i40iw: add files for iwarp interface")
