fcoe: implement FIP VLAN responder

2016-07-20T23:49:41Z

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. Signed-off-by: Hannes Reinecke Acked-by: Johannes Thumshirn Signed-off-by: Martin K.

scsi: Convert uses of compare_ether_addr to ether_addr_equal

2013-10-14T15:25:40Z

Preliminary to removing compare_ether_addr altogether: Use the new bool function ether_addr_equal to add some clarity and reduce the likelihood for misuse of compare_ether_addr for sorting.

scsi: fcoe: fix build error

2013-09-26T23:15:02Z

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 Signed-off-by: Greg Kroah-Hartman

SCSI: fcoe: convert bus code to use bus_groups

2013-09-26T22:49:42Z

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. Cc: Robert Love Cc: "James E.J. Bottomley" Signed-off-by: Greg Kroah-Hartman

libfcoe, fcoe, bnx2fc: Add new fcoe control interface

2012-12-14T18:38:54Z

This patch does a few things. 1) Makes /sys/bus/fcoe/ctlr_{create,destroy} interfaces. These interfaces take an 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. Signed-off-by: Robert Love Acked-by: Neil Horman

libfcoe: Save some memory and optimize name lookups

2012-12-04T18:16:38Z

Instead of creating a structure with an enum and a pointer to a string, simply allocate an array of strings and use the enum values for the indicies. This means that we do not need to iterate through the list of entries when looking up a string name by its enum key. This will also help with a latter patch that will add more fcoe_sysfs attributes that will also use the fcoe_enum_name_search macro. One attribute will also do a reverse lookup which requires less code when the enum-to-string mappings are organized as this patch makes them to be. Signed-off-by: Robert Love Acked-by: Neil Horman
