From f95be3d28d891b0c0f339a504e3aa8e382bbd9a6 Mon Sep 17 00:00:00 2001 From: Gal Pressman Date: Sun, 5 May 2019 20:59:21 +0300 Subject: [PATCH] RDMA: Add EFA related definitions Add EFA driver ID to the IOCTL interface uapi. This patch also adds unspecified node/transport type that will be used by EFA (usnic is left unchanged as it's already part of our ABI).
