Subject: [PATCH RFC v2 0/5] veth: more flexible channels number configuration
Date: Fri, 16 Jul 2021 17:34:18 +0200 [thread overview]
Message-ID: <cover.1626449533.git.pabeni@redhat.com> (raw)
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 covers the feedback provided by Toke and Jakub.
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
Paolo Abeni (5):
veth: always report zero combined channels
veth: factor out initialization helper
veth: implement support for set_channel ethtool op
veth: create by default nr_possible_cpus queues
selftests: net: veth: add tests for set_channel
