From 81bd5ded60c8a369fee6c4d94a0bcb84ad9ce56a Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Wed, 17 Jan 2018 18:51:06 -0800 Subject: [PATCH] nfp: bpf: disable all ctrl vNIC capabilities BPF firmware currently exposes IRQ moderation capability. The driver will make use of it by default, inserting 50 usec delay to every control message exchange. This cuts the number of messages per second we can exchange by almost half. None of the other capabilities make much sense for BPF control vNIC, either. Disable them all. Signed-off-by: Jakub Kicinski Reviewed-by: Dirk van der Merwe Signed-off-by: David S.
