From ac63f8ebcd7ca816bcdd846ff3524954fe01378c Mon Sep 17 00:00:00 2001 From: wenglianfa Date: Thu, 16 Oct 2025 19:40:49 +0800 Subject: [PATCH] RDMA/hns: Fix the modification of max_send_sge [ Upstream commit f5a7cbea5411668d429eb4ffe96c4063fe8dac9e ] The actual sge number may exceed the value specified in init_attr->cap when HW needs extra sge to enable inline feature. Since these extra sges are not expected by ULP, return the user-specified value to ULP instead of the expanded sge number.
