qed: Fix qed_chain_set_prod() for PBL chains with non power of 2 page count

2019-01-04T20:57:30Z

In PBL chains with non power of 2 page count, the producer is not at the beginning of the chain when index is 0 after a wrap. Therefore, after the producer index wrap around, page index should be calculated more carefully. Signed-off-by: Denis Bolotin Signed-off-by: Ariel Elior Signed-off-by: David S. Miller

qed: Expose the doorbell overflow recovery mechanism to the protocol drivers

2018-11-30T21:45:13Z

Most of the doorbelling entities are outside of the core module. L2 queues, Roce queues, iscsi and fcoe all need to register. Make the APIs available for these drivers. Signed-off-by: Ariel Elior Signed-off-by: Michal Kalderon Signed-off-by: Tomer Tayar Signed-off-by: David S. Miller

qed: Add doorbell overflow recovery mechanism

2018-11-30T21:45:12Z

Add the database used to register doorbelling entities, and APIs for adding and deleting entries, and logic for traversing the database and doorbelling once on behalf of all entities.

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.

This patch adds support for tc mqprio offload, using this different traffic classes on the adapter can be utilized based on configured priority to tc map. For example - tc qdisc add dev eth0 root mqprio num_tc 4 map 0 1 2 3 This will cause SKBs with priority 0,1,2,3 to transmit over tc 0,1,2,3 hardware queues respectively.
