This patch set addresses some of the concerns outlined in: https://bugs.launchpad.net/os-vif/+bug/1704485 * Determining the VF number from the netdev's phys_port_name: phys_port_name is read and then cast to an int. Currently there is no standard method to associate a representor with the VF number. phys_port_name has emerged as the "default" choice, but merely casting it as a single number has shortcomings: * A switchdev can potentially have VFs, PFs and physical ports as representors. * A switchdev can have multiple PFs. In this case, the recommendation is to use a parse tree that accepts naming conventions like: * 42 * vf42 * PF1VF42 * vf42@PF1 * Test cases have been added for the above scenarios. * An internal function for PF matching has been added for future use. This is important when PF representors are eventually exposed. Change-Id: I051fcc6fd136b389a6200076bd6fc3b73b626d5e Closes-Bug: #1704485 Signed-off-by: Jan Gutter <jan.gutter@netronome.com>
