what is this? I see no code that handles it either in this patch
or in the later patches?!
Yes, I am not handling these actions in RDS in this patch series. I am
thinking first I should have basic infrastructure in place (and want to
make sure it works and accepted by community) then I will add more
changes for RDS which includes handling socksg actions at RDS level.
But fine, I can add code that handles socksg actions.
Thanks
