Broadcom's 575xx adapter series has support for SRIOV VFs. Making changes to enable SRIOV VF support. There are two major area where changes are done: - Added new DB location for control-path and data-path DB ring - New devices do not need to issue the sriov-config slow-path command thus, skipping to call that firmware command. For now enabling support for 64 RoCE VFs. Link: https://lore.kernel.org/r/1570081715-14301-1-git-send-email-devesh.sharma@broadcom.com Signed-off-by:

The default maximum immediate size is too big for old srp clients, which do not support immediate data. According to the SRP and SRP-2 specifications, the IOControllerProfile attributes for SRP target ports contains the maximum initiator to target iu length. The maximum initiator to target iu length can be obtained by sending MAD packets to query subnet manager port and SRP target ports. We should calculate the max_it_iu_size instead of the default value, when remote maximum initiator to target iu length available.

According to SRP specifications 'srp-r16a' and 'srp2r06', IOControllerProfile attributes for SRP target port include the maximum initiator to target IU size. SRP connection daemons, such as srp_daemon, can get the value from the subnet manager. The SRP connection daemon can pass this value to kernel. This patch adds a parse function for it. Upstream commit [1] enables the kernel parameter, 'use_imm_data', by default. [1] also use (8 * 1024) as the default value for kernel parameter 'max_imm_data'. With those default values, the maximum initiator to target IU size will be 8260. In case the SRPT modules, which include the in-tree 'ib_srpt.ko' module, do not support SRP-2 'immediate data' feature, the default maximum initiator to target IU size is significantly smaller than 8260. For 'ib_srpt.ko' module, which built from source before [2], the default maximum initiator to target IU is 2116. [1] introduces a regression issue for old srp targets with default kernel parameters, as the connection will be rejected because of a too large maximum initiator to target IU size. [1] commit 882981f4 ("RDMA/srp: Add support for immediate data") [2] commit 5dabcd04 ("RDMA/srpt: Add support for immediate data") Link: https://lore.kernel.org/r/20190927174352.7800-1-honli@redhat.com Reviewed-by:
