* RDMA/bnxt_re: Remove dynamic pkey tableKamal Heib2021-11-251-9/+0
| | | | | | | | | | | | The RoCE spec requires RoCE devices to support only the default pkey. However the bnxt_re driver maintains a 0xFFFF entry pkey table and uses only the first entry. Remove the pkey table and hard code a table of length one hard wired with the default pkey.

* RDMA/bnxt_re: Add extended statistics countersSelvin Xavier2021-09-201-0/+28
| | | | | | | | | | | | Implement extended statistics counters for newer adapters. Check if the FW support for this command and issue the FW command only if is supported. Includes code re-organization to handle extended stats. Also, add AH and PD software counters.

* RDMA/bnxt_re: Code refactor while populating user MRsSelvin Xavier2021-01-181-1/+1
| | | | | | | | | | | | | | | Refactor code that populates MR page buffer list. Instead of allocating a pbl_tbl to hold the buffer list, pass the struct ib_umem directly to bnxt_qplib_alloc_init_hwq() as done for other user space memories. Fix the PBL level to handle the above mentioned change. Also, remove an unwanted flag from the input to bnxt_qplib_reg_mr() function.

* RDMA/bnxt_re: Honor vlan_id in GID entry comparisonSelvin Xavier2019-07-221-1/+6
| | | | | | | | | | | | | | | | | | | | A GID entry consists of GID, vlan, netdev and smac. Extend GID duplicate check comparisons to consider vlan_id as well to support IPv6 VLAN based link local addresses. Introduce a new structure (bnxt_qplib_gid_info) to hold gid and vlan_id information. The issue is discussed in the following thread https://lore.kernel.org/r/AM0PR05MB4866CFEDCDF3CDA1D7D18AA5D1F20@AM0PR05MB4866.eurprd05.prod.outlook.com Fixes: 823b23da7113 ("IB/core: Allow vlan link local address based RoCE GIDs") Cc: <stable@vger.kernel.org> # v5.2+ Link: https://lore.kernel.org/r/20190715091913.15726-1-selvin.xavier@broadcom.com Reported-by: Yi Zhang <yi.zhang@redhat.com> Co-developed-by: Parav Pandit <parav@mellanox.com> Signed-off-by: Parav Pandit <parav@mellanox.com> Signed-off-by: Selvin Xavier <selvin.xavier@broadcom.com> Tested-by: Yi Zhang <yi.zhang@redhat.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>

| | | | | | | | | | | | Simplify drivers by ensuring lifetime of ib_ah object. The changes in .create_ah() go hand in hand with relevant update in .destroy_ah(). We will use this opportunity and convert .destroy_ah() to don't fail, as it was suggested a long time ago, because there is nothing to do in case of failure during destroy.

* RDMA/bnxt_re: HW workarounds for handling specific conditionsEddie Wai2017-06-141-0/+2
| | | | | | | | | | | | | | | | | | This patch implements the following HW workarounds 1. The SQ depth needs to be augmented by 128 + 1 to avoid running into an Out of order CQE issue 2. Workaround to handle the problem where the HW fast path engine continues to access DMA memory in retranmission mode even after the WQE has already been completed. If the HW reports this condition, driver detects it and posts a Fence WQE. The driver stops reporting the completions to stack until it receives completion for Fence WQE.

This patch introduces the RoCE driver for the Broadcom NetXtreme-E 10/25/40/50G RoCE HCAs. The RoCE driver is a two part driver that relies on the parent bnxt_en NIC driver to operate. The changes needed in the bnxt_en driver have already been incorporated via Dave Miller's net tree into the mainline kernel.
