From 40b8c45492efc97d9d397475bf475d497fbb9174 Mon Sep 17 00:00:00 2001 From: "Mintz, Yuval" Date: Fri, 7 Apr 2017 11:04:59 +0300 Subject: [PATCH] qede: Prevent VFs from using XDP Current implementation of VFs is very tight in regard to queue resources. VFs support for XDP would require quite a bit of additional infrastructure in qede and qed [sharing of queue-zones between queues, more VF cids, mapping of the doorbell bar, etc.]. For now, prevent XDP programs from being attached to VFs. Signed-off-by: Yuval Mintz Signed-off-by: David S.
