[RFC,0/3] veth: more flexible channels number configuration

Message

Paolo Abeni July 9, 2021, 9:39 a.m. UTC

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.

Paolo Abeni (3):
  veth: implement support for set_channel ethtool op
  veth: make queues nr configurable via kernel module params
  selftests: net: veth: add tests for set_channel
