From 9abb0d1bbd9529c574eacd8586e2bf68d17966cd Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Tue, 27 Jun 2017 16:49:53 +0300 Subject: RDMA: Simplify get firmware interface There is a need to forward FW version to user space application through RDMA netlink. In order to make it safe, there is need to declare nla_policy and limit the size of FW string. The new define IB_FW_VERSION_NAME_MAX will limit the size of FW version string. That define was chosen to be equal to ETHTOOL_FWVERS_LEN, because many drivers anyway are limited by that value indirectly. The introduction of this define allows us to remove the string size from get_fw_str function signature.
