Merge branch 'veth-flexible-channel-numbers'
Paolo Abeni says:
====================
veth: more flexible channels number configuration
XDP setups can benefit from multiple veth RX/TX queues. Currently
veth allow setting such number only at creation time via the
'numrxqueues' and 'numtxqueues' parameters.
This series introduces support for the ethtool set_channel operation
and allows configuring the queue number via a new module parameter.
The veth default configuration is not changed.
Finally self-tests are updated to check the new features, with both
valid and invalid arguments.
This iteration is a rebase of the most recent RFC, it does not provide
a module parameter to configure the default number of queues, but I
think could be worthy
RFC v1 -> RFC v2:
- report more consistent 'combined' count
- make set_channel as resilient as possible to errors
- drop module parameter - but I would still consider it.
- more self-tests
====================
