Luoyouming c5a6776e44 RDMA/hns: Fix incorrect sge nums calculation ... [ Upstream commit 0c5e259b06 ] The user usually configures the number of sge through the max_send_sge parameter when creating qp, and configures the maximum size of inline data that can be sent through max_inline_data. Inline uses sge to fill data to send. Expect the following: 1) When the sge space cannot hold inline data, the sge space needs to be expanded to accommodate all inline data 2) When the sge space is enough to accommodate inline data, the upper limit of inline data can be increased so that users can send larger inline data Currently case one is not implemented. When the inline data is larger than the sge space, an error of insufficient sge space occurs. This part of the code needs to be reimplemented according to the expected rules. The calculation method of sge num is modified to take the maximum value of max_send_sge and the sge for max_inline_data to solve this problem. Fixes: 05201e01be ("RDMA/hns: Refactor process of setting extended sge") Fixes: 30b707886a ("RDMA/hns: Support inline data in extented sge space for RC") Link: https://lore.kernel.org/r/20221108133847.2304539-3-xuhaoyue1@hisilicon.com Signed-off-by: Luoyouming <luoyouming@huawei.com> Signed-off-by: Haoyue Xu <xuhaoyue1@hisilicon.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> Signed-off-by: Sasha Levin <sashal@kernel.org>		2022-12-31 13:32:33 +01:00
