The user might want to modify the values for R_A_TOV and E_D_TOV, so add new module parameters 'e_d_tov' and 'r_a_tov' for the 'fcoe' modules and allow to modify them via sysfs attributes.

When running in VN2VN mode there is no central instance which would send out any FIP VLAN discovery notifications. So this patch adds a new sysfs attribute 'fip_vlan_responder' which will activate a FIP VLAN discovery responder.

I had a typo in a variable name for the previous patch (SCSI: fcoe: convert bus code to use bus_group) that broke the build, this fixes that. Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
The bus_attrs field of struct bus_type is going away soon, dev_groups should be used instead. This converts the fcoe bus code to use the correct field.

Declare local variables and functions 'static'. This patch does not change any functionality. Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Robert Love <robert.w.love@intel.com>
This patch does a few things.
1) Makes /sys/bus/fcoe/ctlr_{create,destroy} interfaces.
These interfaces take an <ifname> and will either
create an FCoE Controller or destroy an FCoE
Controller depending on which file is written to.
The new FCoE Controller will start in a DISABLED
state and will not do discovery or login until it
is ENABLED. This pause will allow us to configure
the FCoE Controller before enabling it.
2) Makes the 'mode' attribute of a fcoe_ctlr_device
writale. This allows the user to configure the mode
in which the FCoE Controller will start in when it
is ENABLED.
Possible modes are 'Fabric', or 'VN2VN'.
The default mode for a fcoe_ctlr{,_device} is 'Fabric'.
Drivers must implement the set_fcoe_ctlr_mode routine
to support this feature.
libfcoe offers an exported routine to set a FCoE
Controller's mode. The mode can only be changed
when the FCoE Controller is DISABLED.
This patch also removes the get_fcoe_ctlr_mode pointer
in the fcoe_sysfs function template, the code in
fcoe_ctlr.c to get the mode and the assignment of
the fcoe_sysfs function pointer to the fcoe_ctlr.c
implementation (in fcoe and bnx2fc). fcoe_sysfs can
return that value for the mode without consulting the
LLD.
3) Make a 'enabled' attribute of a fcoe_ctlr_device. On a
read, fcoe_sysfs will return the attribute's value. On
a write, fcoe_sysfs will call the LLD (if there is a
callback) to notifiy that the enalbed state has changed.
This patch maintains the old FCoE control interfaces as
module parameters, but it adds comments pointing out that
the old interfaces are deprecated.
