2016-12-05i40iw: Fill in IRD value when on connect requestShiraz Saleem
IRD is not populated on connect request and application is getting 0 for the value. Fill in the correct value on connect request. Signed-off-by: Shiraz Saleem <shiraz.saleem@intel.com> Signed-off-by: Faisal Latif <faisal.latif@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
2016-12-05i40iw: Set TOS field in IP headerShiraz Saleem
Set the TOS field in IP header with the value passed in from application. If there is mismatch between the remote client's TOS and listener, set the listener Tos to the higher of the two values.

2016-12-05i40iw: Add missing cleanup on device closeMustafa Ismail
On i40iw device close, disconnect all connected QPs by moving them to error state; and block further QPs, PDs and CQs from being created. Additionally, make sure all resources have been freed before deallocating the ibdev as part of the device close.

2016-12-05i40iw: Utilize physically mapped memory regionsHenry Orosco
Add support to use physically mapped WQ's and MR's if determined that the OS registered user-memory for the region is physically contiguous. This feature will eliminate the need for unnecessarily setting up and using PBL's when not required.

2016-12-05i40iw: Fix incorrect assignment of SQ headHenry Orosco
The SQ head is incorrectly incremented when the number of WQEs required is greater than the number available. The fix is to use the I40IW_RING_MOV_HEAD_BY_COUNT macro. This checks for the SQ full condition first and only if SQ has room for the request, then we move the head appropriately.

2016-12-05i40iw: Remove variable flush_code and check to set qp->sq_flushHenry Orosco
The flush_code variable in i40iw_bld_terminate_hdr() is obsolete and the check to set qp->sq_flush is unreachable. Currently flush code is populated in setup_term_hdr() and both SQ and RQ are flushed always as part of the tear down flow.

2016-12-05i40iw: Remove NULL check for cm_node->iwdevHenry Orosco
It is not necessary to check cm_node->iwdev in i40iw_rem_ref_cm_node() as it can never be NULL after a successful call out of i40iw_make_cm_node().

2016-12-05i40iw: Remove checks for more than 48 bytes inline dataHenry Orosco
Remove dead code, which isn't executed because we return error if the data size is greater than 48 bytes. Inline data size greater than 48 bytes isn't supported and the maximum WQE size is 64 bytes.

Some resources are consumed internally and not available to the user.

2016-12-05i40iw: Use vector when creating CQsHenry Orosco
Assign each CEQ vector to a different CPU when possible, then when creating a CQ, use the vector for the CEQ id. This allows completion work to be distributed over multiple cores.

2016-12-05i40iw: Convert page_size to encoded valueHenry Orosco
Passed in page_size was used as encoded value for writing the WQE and passed in value was usually 4096. This was working out since bit 0 was 0 and implies 4KB pages, but would not work for other page sizes.
