'dummy_pmd' class is a replacement for 'dummy' class.
Created in purposes of testing of PMD interfaces.
May be activated instead of usual 'dummy' by additional
parameter 'pmd' to --enable-dummy.
Ex.:
ovs-vswitchd --enable-dummy=pmd
or
ovs-vswitchd --enable-dummy=override,pmd
Name of 'dummy_pmd' class is "dummy". So, all ports should be
added as usual:
ovs-vswitchd set interface <iface> type=dummy
