From 1d11d26cf0d6974551049a3d7353ee1336b8632e Mon Sep 17 00:00:00 2001 From: Shiraz Saleem Date: Tue, 24 Nov 2020 18:56:17 -0600 Subject: [PATCH] RDMA/i40iw: Remove push code from i40iw The push feature does not work as expected in x722 and has historically been disabled in the driver. Purge all remaining code related to the push feature in i40iw.
