No; we have no support for doing that.

For specific drivers, you could patch in something similar.  For example, in the Intel driver, if you were to delete the "If link is already up, do not attempt to reset the PHY" portion of intel_reset(), then performing "ifclose" should reset the chip including a link-level reset.
