In direct attach mode, if port features like QoS/Trunk/FEC/CR are enabled, driver can receive PLOGI from the target before firmware notifies lport online to the driver.

This patch includes change to enable firmware patch simplication feature. This feature is targeted to address the requirement to have independent patch release for firmware. Prior to 3.2.3, releasing a patch fix for firmware requires changes to bfa, to use new firmware images. But with these changes, if the new firmware is flashed on to the HBA with brocade adapter management utilites, driver uses the new firmware after checking the patch release byte in the firmware version.

Bfa driver crash is observed while pushing the firmware on to chinook quad port card due to uninitialized bfi_image_ct2 access which gets initialized only for CT2 ASIC based cards after request_firmware(). For quard port chinook (CT2 ASIC based), bfi_image_ct2 is not getting initialized as there is no check for chinook PCI device ID before request_firmware and instead bfi_image_cb is initialized as it is the default case for card type check. This patch includes changes to read the right firmware for quad port chinook.

Root cause: When kernel crashes, On brocade 815/825 adapters, bfa IOC state machine and FW doesn't get a notification and hence are not cleanly shutdown. So registers holding driver/IOC state information are not reset back to valid disabled/parking values. This causes subsequent driver initialization to fail during kdump kernel boot. Fix description: during the initialization of first PCI function, reset corresponding register when unclean shutown is detect by reading chip registers. This will make sure that ioc/fw gets clean re-initialization. Signed-off-by: NVijaya Mohan Guvva <vmohan@brocade.com> Signed-off-by: NJames Bottomley <JBottomley@Parallels.com>

D-Port is a new port type created with the intention of running link level diagnostic tests like loopback, traffic test. In static D-port mode, user configures the port to D-port mode and starts the test, but in dynamic D-port, once the Brocade switch port is configured to D-port, it will reject the regular FLOGI from HBA with reason that it is in D-port mode. So based on the reason code HBA port will turn itself into D-port and start diagnostic test.

由 Vijay Mohan Guvva 提交于
When a switch disable/enable or a reboot is done, the HBA port gets an offline and a subsequent online notification. When the port comes up a link up notification is sent to bfa from the firmware. The bfa then send an FLOGI to the firmware which is sent out on the wire. The switch port meanwhile goes offline (presumably for diagnostics) which causes the switch not to respond to the FLOGI. The link down notification is sent to the HBA driver. However owing to a bug in the lps state machine handling the lps state machine does not move to sm_init state (it remains in sm_login state and send a login complete message to fcs). This results in a zero PID assignment as the login is not really complete. This fix is to correctly handle the events in lps state machine.

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.
