From e7b80dece83b86f8f630a47a9e0419051c7b1005 Mon Sep 17 00:00:00 2001 From: "Mintz, Yuval" Date: Sun, 4 Jun 2017 13:31:09 +0300 Subject: [PATCH] qede: VF XDP support This introduces 2 changes needed for XDP to be supported for VFs: a. On VF-side, publish the NDO based on qed outputs b. On PF-side, request qed to allocate sufficient cids per-VF to allow the child vfs to support it Signed-off-by: Yuval Mintz Signed-off-by: David S.
