RDMA/bnxt_re: Add a max slot check for SQ
Overview
Description

In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Add a max slot check for SQ The variable WQE mode must be validated against the maximum slots supported by HW. The max supported value is 64K. Adding a max and min check and fail if user supplied value is more than the max supported and zero.
