| * [SCSI] bnx2fc: call ctlr_link_up only when the interface is enabledBhanu Prakash Gollapudi2011-10-161-0/+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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [SCSI] bnx2fc: Introduce interface structure for each vlan interfaceBhanu Prakash Gollapudi2011-07-276-495/+467
| | | | | | | | | | | | | | | | | | Currently, bnx2fc has a hba structure that can work with only a single vlan interface. When there is a change in vlan id, it does not have the capability to switch to different vlan interface. To solve this problem, a new structure called 'interface' has been introduced, and each hba can now have multiple interfaces, one per vlan id. Most of the patch is a moving the interface specific fields from hba to the interface structure, and appropriately modifying the dereferences. A list of interfaces (if_list) is maintained along with adapter list. During a create call, the interface structure is allocated and added to if_list and deleted & freed on a destroy call. Link events are propagated to all interfaces belonging to the hba. Signed-off-by: Bhanu Prakash Gollapudi <bprakash@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
