The problem hasn't arisen so far because NVME_MAX_VFS has been 127. This patch separated identify data itself from the actual secondary controller list managed by controller to support more than 127 secondary controllers with the following patch. This patch reused NvmeSecCtrlEntry structure to manage all the possible secondary controllers, and copy entries to identify data structure when the command comes in.
