Hi Experts,
Please help me review two new probes interface for COMSTAR FC target.
It's a complement for [PSARC/2009/291 FastTrack]
Here's the doc:

Your comments before Jun 26 will be very much appreciated!
Allan,
Since this is public list, you will have to post your text file
either via email, or to opensolaris.org somewhere. Otherwise,
community members cannot read it.
It is probably easiest to just send it in email.
Thanks!

Hi Dan,
Thank you for reminding me.
Here's the doccument:
4. Technical Description
The fc provider provides probes for tracing fibre channel port provider
activity.
This is a kernel provider built into the COMSTAR fc target port provider.
This project proposes to add two new providers to trace RSCN and ABTS packets
4.1 Probes overview
Fibre Channel Event Type Probes
------------------------ ------
rscn receive fc:::rscn-receive
abts receive fc:::abts-receive
4.2 Probe argument commonality
These new providers follow the arguments rules of PSARC case 2009/291,
no new arguments defined.
4.3 Detailed probes specification
4.3.1 RSCN Packet Probes
fc:::rscn-receive trace all RSCN packets target port received
Probes Variable Type Description
----- --------- ---- -----------
fc:::rscn-receive args[0] conninfo_t * connection info
fc:::rscn-receive args[1] fc_port_info_t * local port info
fc:::rscn-receive args[2] int port id
args[2] is the port id which retrived from RSCN pages
4.3.2 ABTS Packet Probes
Probes Variable Type Description
------ -------- ---- -----------
fc:::abts-receive args[0] conninfo_t * connection info
fc:::abts-receive args[1] fc_port_info_t * local port info
fc:::abts-receive args[2] fc_port_info_t * remote port info

5. Reference Documents:

PSARC/2007/523 COMSTAR: Common Multiprotocol SCSI Target
6. Resources and Schedule
6.4. Steering Committee requested information
6.4.1. Consolidation C-team Name:
ON
6.5. ARC review type: FastTrack
6.6. ARC Exposure: open
Thanks,
