Hi Team, In the old UV design, we said that in order to use the /dev/net network device nodes, applications need to be ported to use libdlpi, and libdlpi will first try to open the /dev/net node, and if that fails, falls back to open the /dev node.
I think that approach causes randomness. Most of DLPI applications (and all DLPI appliations that were ported to use libdlpi, I believe) should open the /dev/net network device nodes without problem, and if there is any problem, it should be a bug in the UV gates. So that I propose to change the behavior to don't fallback to /dev nodes in the common case, but add a DLPI_LEGACY flag to libdlpi. If that flag is set, only open the legacy /dev nodes. (This might be needed for some application). Further, we will keep the DLPI_LEGACY environment variable. If that is set, open the /dev nodes. This might be useful for diagnose purpose, so that it won't be documented. What do you think. - Cathy
