How to check and confirm whether a module option has been applied?

Issue

• What command can be used to verify that module parameters are currently  applied?
• For example, the qla2xxx module is loaded into the kernel :

        [root@host ~]# lsmod |grep qla2xxx
        qla2xxx              1019552  235 
        qla2xxx_conf          310408  1 
        scsi_mod              152465  7 sg,sr_mod,qla2xxx,libata,megaraid_sas,usb_storage,sd_mod
        [root@host ~]# 

• In modprobe.conf :

        [root@host ~]# grep options /etc/modprobe.conf|grep -v bond0
        options qla2xxx qlport_down_retry=1 ql2xfailover=0 ConfigRequired=0

• Question on module options
• As you know, kernel driver modules can often be loaded with some options being specified. An obvious case is the bonding driver but it’s true for many other drivers as well.
• One thing I don’t seem to be able to find out is what options/parameters a module has been loaded with. We can always look in the appropriate module options file under /etc/modprobe.d but there’s no guarantee that the file hasn’t been edited after the module was loaded.
• Is there any way to interrogate the system to find out what values of the various options are in force?
