Hi Tom,
What is the purpose of this?
Is there a reason you did it only for mthca and not mlx4?

SRP I/O with small block sizes causes a high CPU load. Processing IB

This series of four patches adds SRP_CRED_REQ support in ib_srp, which is a
feature defined by the SRP (draft) standard. Compared to an earlier patch for
implementing this functionality that I posted a few months ago I have done my
best to address all comments that were posted to this mailing
The patch below realizes the following transformations on the symbolic
constants defined in ib_srp.h and used in ib_srp.h and ib_srp.c:
* Added the constants SRP_RQ_MASK and SRP_SQ_MASK.
* Renamed SRP_SQ_SIZE into SRP_REQ_SQ_SIZE.
* Changed the value of SRP_SQ_SIZE from 63 to 64.
Note: this patch
This patch enables allocation of request and response information units on the
send queue instead of only requests, and implements processing of SRP_CRED_REQ
information units. Also, declarations have been added to include/scsi/srp.h
for the SRP_CRED_REQ and SRP_CRED_RSP information units.
Makes sure that the SCSI mid-layer never tries to queue more than
(SRP request limit) - 1 SCSI commands. Improves performance for targets whose
request limit is less than or equal to SRP_SQ_REQ_SIZE (63) by reducing the
number of BUSY responses.

Exports req_lim via sysfs, which is convenient for debugging purposes.

Hi Tziporet,
I just picked mthca arbitrarily to demonstrate how to do it. If people
like the verb, then I'll do it for all the devices, but I didn't want to

Add cleanup to remove CR from SP and EP
during DTO errors in dapli_evd_cqe_to_event.
dapl_sp_remove_ep needs to remove cr_ptr
reference from EP before freeing cr object.

When transitioning a QP to the error state, in progress RWQEs need
to be marked complete. This also involves releasing the reference
count to the memory regions referenced in the SGEs. The locking in
the receive packet processing wasn't sufficient to prevent
qib_error_qp() from modifying the r_sge
