r11980: ronnie worked out that opcode 0xb in SMB2 is in fact ioctl, and that
it only appeared to be like a SMBtrans request as it was being called
with function 0x11c017 which is "named pipe read write"
I wonder if this means we could do DCE/RPC over SMB using ntioctl
calls as well?
(This used to be commit f2b8857797328be64b0b85e875ae6d108e2aeaaa)
