driver: tun: Use new macro SOCK_IOC_TYPE instead of literal number 0x89 The current codes use _IOC_TYPE(cmd) == 0x89 to check if the cmd is one socket ioctl command like SIOCGIFHWADDR. But the literal number 0x89 may confuse readers. So create one macro SOCK_IOC_TYPE to enhance the readability. Signed-off-by: Gao Feng <fgao@ikuai8.com> Signed-off-by: David S.
