Subject: nfp: bpf: disable all ctrl vNIC capabilities
Patch-mainline: v4.16-rc1
Git-commit: 81bd5ded60c8a369fee6c4d94a0bcb84ad9ce56a
References: bsc#1109837
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.
