Hi David and Laszlo, This patch is not focused on the discussion about the multiple NICs existed case, just use to update the ping command option. So, please don't misunderstand.
For the discussion in <http://thread.gmane.org/gmane.comp.bios.edk2.devel/10046>, If there are multiple NICs existed in the platform and no source IP is specified (no '-s' option), the first NIC will be selected as default interface to ping the target. '-s SourceIp' can be used to specify any interface you want. That's the current implementation choice. I agree your and Bhupesh 's option to support no source IP specified case, that's meaningful to improve the command's friendliness(Windows and Linus do this resolution). How about selecting the first both connected and configured interface automatically? If so, I can create another patch to support that solution. Thanks.
