Martin,

Please apply the updated qla2xxx patch series implementing SAN
Congestion Management (SCM) support to the scsi tree at your
earliest convenience.

We will follow this up with another patchset to add SCM statistics to
the scsi transport fc, as recommended by James.

v3->v4:
1. Removed unused structure highlighted by Himanshu.
2. Addressed issues highlighted by James.
3. Changed the use of GFP_ATOMIC allocations to be the exception
than the norm during FPIN events.

v2->v3:
1. Updated Reviewed-by tags

v1->v2:
1. Applied changes to address warnings highlighted by Bart.
2. Removed data structures and functions that should be part of fc
transport, to be send out in a follow-up patchset.
3. Changed the existing code to use definitions from fc transport
headers.

Thanks,
Nilesh
