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. Signed-off-by: Leon Romanovsky <leonro@mellanox.com>
