New Revision: 11891
WebSVN: http://websvn.samba.org/cgi-bin/viewcvs.cgi?view=rev&root=samba&rev=11891
Log:
- added pipe_flags field in smb2_trans
- while running dcerpc over SMB2, the server will occasionally send us
a oh-so-useful STATUS_PENDING result meaning "I don't have a result
for you yet, but I'm working on it". These can be discarded :-)
