2013-04-25bnx2x, bnx2fc: Use per port max exchange resourcesBhanu Prakash Gollapudi1-15/+20
The firmware supports a maximum of 4K FCoE exchanges. In 4-port devices, or when working in multi-function mode, this resource needs to be distributed between the various possible FCoE functions. This information needs to be calculated by bnx2x and propagated into bnx2fc via cnic. bnx2fc can then use this value to calculate corresponding xid resources instead of using global constants.

2013-03-25bnx2fc: Make the fcoe_cltr the SCSI host parentRobert Love1-3/+2
The fcoemon userspace daemon is searching for the a hostX under the the /sys/bus/fcoe/devices/ctlrX/ entries. When interfaces created using fcoe_sysfs and fcoe.ko this linkage is setup correctly, but bnx2fc is not doing the same thing and therefore fcoemon does not create the fcoe interface for bnx2fc. This patch sets up the correct linkage for bnx2fc such that fcoemon will work correctly with fcoe_sysfs and bnx2fc.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers.

2012-12-14bnx2fc: Use the fcoe_sysfs control interfaceRobert Love1-29/+139
This patch adds support for the new fcoe_sysfs control interface to bnx2fc.ko. It keeps the deprecated interface in tact and therefore either the legacy or the new control interfaces can be used. A mixed mode is not supported. A user must either use the new interfaces or the old ones, but not both. The fcoe_ctlr's link state is now driven by both the netdev link state as well as the fcoe_ctlr_device's enabled attribute. The link must be up and the fcoe_ctlr_device must be enabled before the FCoE Controller starts discovery or login.

2012-12-14libfcoe, fcoe, bnx2fc: Add new fcoe control interfaceRobert Love1-1/+0
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.

This patch has the SW FCoE driver and the bnx2fc driver make use of the new fcoe_sysfs API added earlier in this patch series. After this patch a fcoe_ctlr_device is allocated with private data in this order. +------------------+ +------------------+ | fcoe_ctlr_device | | fcoe_ctlr_device | +------------------+ +------------------+ | fcoe_ctlr | | fcoe_ctlr | +------------------+ +------------------+ | fcoe_interface | | bnx2fc_interface | +------------------+ +------------------+ libfcoe also takes part in this new model since it discovers and manages fcoe_fcf instances. The memory allocation is different for FCFs. I didn't want to impact libfcoe's fcoe_fcf processing, so this patch creates fcoe_fcf_device instances for each discovered fcoe_fcf. The two are paired using a (void * priv) member of the fcoe_ctlr_device. This allows libfcoe to continue maintaining its list of fcoe_fcf instances and simply attaches and detaches them from existing or new fcoe_fcf_device instances.

2012-05-23[SCSI] bnx2fc: Allocate fcoe_ctlr with bnx2fc_interface, not as a memberRobert Love1-42/+74
Currently the fcoe_ctlr associated with an interface is allocated as a member of struct bnx2fc_interface. This causes problems when when later patches attempt to use the new fcoe_sysfs APIs which allow us to allocate the bnx2fc_interface as private data to a fcoe_ctlr_device instance. The problem is that libfcoe wants to be able use pointer math to find a fcoe_ctlr's fcoe_ctlr_device as well as finding a fcoe_ctlr_device's assocated fcoe_ctlr. To do this we need to allocate the fcoe_ctlr_device, with private data for the LLD. The private data will contain the fcoe_ctlr and its private data will be the bnx2fc_interface. +-------------------+ | fcoe_ctlr_device | +-------------------+ | fcoe_ctlr | +-------------------+ | bnx2fc_interface | +-------------------+ This prep work will allow us to go from a fcoe_ctlr_device instance to its fcoe_ctlr as well as from a fcoe_ctlr to its fcoe_ctlr_device once the fcoe_sysfs API is in use (later patches in this series).

2011-10-16[SCSI] bnx2fc: call ctlr_link_up only when the interface is enabledBhanu Prakash Gollapudi1-0/+2
Link may not be up when the driver receives ulp_start event, and hence fcoe_ctlr_link_up is not called. Call fcoe_ctlr_link_up during indicate_netevent only when the interface is enabled. (It has to be called when enabled because that is an indication that the vlan discovery is completed).

2011-09-17[SCSI] bnx2fc: Avoid calling bnx2fc_if_destroy with unnecessary locksBhanu Prakash Gollapudi1-6/+2
It is not required to hold rtnl_lock and bnx2fc_dev_lock when calling bnx2fc_if_destroy, as the locking is only required to serialize creation and deletion of fcoe instances. More importantly, this unnecessary locking causes deadlock as bnx2fc_if_destroy calls fc_remove_host holding rtnl_lock.

2011-09-17[SCSI] bnx2fc: Validate vlan id in NETDEV_UNREGISTER handlerNithin Nayak Sujir1-3/+3
When bnx2fc receives an UNREGISTER event on a vlan interface it calls destroy on all interfaces that matches the physical interface. Add vlan_id check to destroy only the vlan interface that generated the event.

2011-09-17[SCSI] bnx2fc: Send solicitation only after vlan discovery is completeBhanu Prakash Gollapudi1-4/+17
Link up event is generated to the driver even before vlan discovery has started. Because of this driver can send discovery solicitation on a stale vlan. Call fcoe_ctlr_link_up() only when the driver is in enabled state, which implies the vlan discovery is complete before sending solicitation.

2011-09-15net: consolidate and fix ethtool_ops->get_settings callingJiri Pirko1-1/+3
This patch does several things: - introduces __ethtool_get_settings which is called from ethtool code and from drivers as well. Put ASSERT_RTNL there. - dev_ethtool_get_settings() is replaced by __ethtool_get_settings() - changes calling in drivers so rtnl locking is respected. In iboe_get_rate was previously ->get_settings() called unlocked. This fixes it. Also prb_calc_retire_blk_tmo() in af_packet.c had the same problem. Also fixed by calling __dev_get_by_index() instead of dev_get_by_index() and holding rtnl_lock for both calls. - introduces rtnl_lock in bnx2fc_vport_create() and fcoe_vport_create() so bnx2fc_if_create() and fcoe_if_create() are called locked as they are from other places. - use __ethtool_get_settings() in bonding code Signed-off-by: Jiri Pirko <jpirko@redhat.com> v2->v3: -removed dev_ethtool_get_settings() -added ASSERT_RTNL into __ethtool_get_settings() -prb_calc_retire_blk_tmo - use __dev_get_by_index() and lock around it and __ethtool_get_settings() call v1->v2: add missing export_symbol Reviewed-by: Ben Hutchings <bhutchings@solarflare.com> [except FCoE bits] Acked-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S.
