Explain what about it?  What "Ma" is, or what the operation is?

"SMB Ma" is short for "SMB Mailslot"; it's cut short because the 
Protocol column is too narrow - try dragging the line between "Protocol" 
and "Info" to the write if you want to see it all.

SMB mailslots (and much of the rest of SMB) are documented in CIFS 
Technical Reference 1.00:

I *suspect* mailslots were an interprocess communication mechanism in 
OS/2 (but don't know whether that was the case); they allow messages to 
be sent between machines, and are used for some "side protocols" used 
with SMB (such as browsing for servers).
