xen/netback: set default upper limit of tx/rx queues to 8
[ Upstream commit 56dd5af9bc23d0d5d23bb207c477715b4c2216c5 ]
The default for the maximum number of tx/rx queues of one interface is
the number of cpus of the system today. As each queue pair reserves 512
grant pages this default consumes a ridiculous number of grants for
large guests.
Limit the queue number to 8 as default. This value can be modified
via a module parameter if required.
