RDMA/qedr: Remove enumerated type qed_roce_ll2_tx_dest

2018-10-01T01:21:11Z

Clang warns when one enumerated type is explicitly converted to another. drivers/infiniband/hw/qedr/qedr_roce_cm.c:198:28: warning: implicit conversion from enumeration type 'enum qed_roce_ll2_tx_dest' to different enumeration type 'enum qed_ll2_tx_dest' [-Wenum-conversion] ll2_tx_pkt.tx_dest = pkt->tx_dest; ~ ~~~~~^~~~~~~ 1 warning generated. Turns out that QED_ROCE_LL2_TX_DEST_NW and QED_ROCE_LL2_TX_DEST_LB are only used once in the whole tree and QED_ROCE_LL2_TX_DEST_MAX is used nowhere. Remove them and use the equivalent values from qed_ll2_tx_dest in their place.

qed*: Utilize FW 8.37.2.0

2018-06-05T14:48:09Z

This FW contains several fixes and features. RDMA - Several modifications and fixes for Memory Windows - drop vlan and tcp timestamp from mss calculation in driver for this FW - Fix SQ completion flow when local ack timeout is infinite - Modifications in t10dif support ETH - Fix aRFS for tunneled traffic without inner IP. - Fix chip configuration which may fail under heavy traffic conditions. - Support receiving any-VNI in VXLAN and GENEVE RX classification. iSCSI / FcoE - Fix iSCSI recovery flow - Drop vlan and tcp timestamp from mss calc for fw 8.37.2.0 Misc - Several registers (split registers) won't read correctly with ethtool -d Signed-off-by: Ariel Elior Signed-off-by: Manish Rangankar Signed-off-by: Michal Kalderon Signed-off-by: David S.

qed: Add srq core support for RoCE and iWARP

2018-06-04T21:09:54Z

This patch adds support for configuring SRQ and provides the necessary APIs for rdma upper layer driver (qedr) to enable the SRQ feature. Signed-off-by: Michal Kalderon Signed-off-by: Ariel Elior Signed-off-by: Yuval Bason Signed-off-by: David S. Miller

qed: iWARP CM add error handling

2017-07-03T08:43:45Z

This patch introduces error handling for errors that occurred during connection establishment. Signed-off-by: Michal Kalderon Signed-off-by: Yuval Mintz Signed-off-by: Ariel Elior Signed-off-by: David S. Miller

qed: iWARP implement disconnect flows

2017-07-03T08:43:45Z

This patch takes care of active/passive disconnect flows. Disconnect flows can be initiated remotely, in which case a async event will arrive from peer and indicated to qedr driver. These are referred to as exceptions. When a QP is destroyed, it needs to check that it's associated ep has been closed.

qed: iWARP CM add active side connect

2017-07-03T08:43:45Z

This patch implements the active side connect. Offload a connection, process MPA reply and send RTR. In some of the common passive/active functions, the active side will work in blocking mode.

qed: iWARP CM add passive side connect

2017-07-03T08:43:45Z

This patch implements the passive side connect. It addresses pre-allocating resources, creating a connection element upon valid SYN packet received. Calling upper layer and implementation of the accept/reject calls. Error handling is not part of this patch.

qed: iWARP CM add listener functions and initial SYN processing

2017-07-03T08:43:45Z

This patch adds the ability to add and remove listeners and identify whether the SYN packet received is intended for iWARP or not. If a listener is not found the SYN packet is posted back to the chip. Signed-off-by: Michal Kalderon Signed-off-by: Yuval Mintz Signed-off-by: Ariel Elior Signed-off-by: David S. Miller

qed: Implement iWARP initialization, teardown and qp operations

2017-07-03T08:43:44Z

This patch adds iWARP support for flows that have common code between RoCE and iWARP, such as initialization, teardown and qp setup verbs: create, destroy, modify, query. It introduces the iWARP specific files qed_iwarp.[ch] and iwarp_common.h Signed-off-by: Michal Kalderon Signed-off-by: Yuval Mintz Signed-off-by: Ariel Elior Signed-off-by: David S. Miller

qed*: Rename qed_roce_if.h to qed_rdma_if.h

2017-06-21T19:32:59Z

Rename the qed_roce_if file to qed_rdma_if as it represents a common interface for RoCE and iWARP. this commit affects RDMA/qedr as well. Signed-off-by: Michal Kalderon Signed-off-by: Yuval Mintz Signed-off-by: David S. Miller
