Use 'make namespacecheck' to code that could be declared static. After that remove code that is not being used. Compile tested only. Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-12-18bna: Firmware Patch SimplificationRasesh Mody1-27/+591
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 the 3.2.3.0 firmware, releasing a patch fix for firmware would require changes to bna driver, to use new firmware images. However with these changes, if the new firmware is flashed on to the Adapter, the driver will use the new firmware after checking the patch release byte in the firmware version. Update the f/w version to 3.2.3.0 Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-10-04bna: Multiple Definition and Interface Setup FixRasesh Mody1-1/+4
drivers/net/built-in.o: In function `bfa_ioc_ct2_poweron': (.text+0xcdc90): multiple definition of `bfa_ioc_ct2_poweron' drivers/scsi/built-in.o:(.text+0x17f9a0): first defined here This patch renames bfa_ioc_ct2_poweron() to bfa_nw_ioc_ct2_poweron() to avoid multiple definition with Brocade scsi driver. It also modifies asic specific interface setup to allocate MSIX resources at power on in case of 1860 HW with no asic block and warns if the asic gen is neither BFI_ASIC_GEN_CT nor BFI_ASIC_GEN_CT2.

2011-08-11bna: ENET and Tx Rx Redesign EnablementRasesh Mody1-136/+253
Change details: This patch contains additional structure and function definition changes that are required to enable the new msgq/enet/txrx redesign introduced by the previous 4 patches. - structure and function definition changes to header files as a result of Ethport, Enet, IOCEth, Tx, Rx redesign. - ethtool changes to use new enet function and definitions - Set number of Tx and Rx queues bassed on underlying hardware. Define separate macros for maximum and supported numbers of Tx and Rx queues based on underlying hardware. Take VLAN header into account for MTU calculation. Default to INTx mode when pci_enable_msix() fails. Set a bit in Rx poll routine, check and wait for that bit to be cleared in the cleanup routine before proceeding. - The TX and Rx coalesce settings are programmed in steps of 5 us. The value that are not divisible by 5 are rounded to the next lower number. This was causing the value os 1 to 4 to be rounded to 0, which is an invalid setting. When creating Rx and Tx object, we are currently assigning the default values of Rx and Tx coalescing_timeo. If these values are changed in the driver to a different value, the change is lost during such operations as MTU change. In order to avoid that, pass the configured value of coalescing_timeo before Rx and Tx object creation. Fix bnad_tx_coalescing_timeo_set() so it applies to all the Tx objects. - Reorg uninitialization path in case of pci_probe failure. - Hardware clock setup changes to pass asic generation, port modes and asic mode as part firmware boot parameters to firmware. - FW mailbox interface changes to defined asic specific mailbox interfaces. h/w mailbox interfaces take 8-bit FIDs and 2-bit port id for owner. Cleaned up mailbox definitions and usage for new and old HW. Eliminated usage of ASIC ID. MSI-X vector assignment and programming done by firmware. Fixed host offsets for CPE/RME queue registers. - Implement polling mechanism for FW ready to have poll mechanism replaces the current interrupt based FW READY method. The timer based poll routine in IOC will query the ioc_fwstate register to see if there is a state change in FW, and sends the READY event. Removed infrastructure needed to support mbox READY event from fw as well as IOC code. - Move FW init to HW init. Handle the case where PCI mapping goes away when IOCPF state machine is waiting for semaphore. - Add IOC mbox call back to client indicating that the command is sent.

2011-08-11bna: MSGQ ImplementationRasesh Mody1-5/+9
Change details: - Currently modules communicate with the FW using 32 byte command and response register. This limits the size of the command and response messages exchanged with the FW to 32 bytes. We need a mechanism to exchange the comamnds and responses exchange with FW that exceeds 32 bytes. - MSGQ implementation provides that facility. It removes the assumption that command/response queue size is precisely calculated to accommodate all concurrent FW commands/responses. The queue depth is made variable now, defined by a macro. A waiting command list is implemented to hold all the commands when there is no place in the command queue. Callback is implemented for each command entry to invoke the module posting the command, when there is space in the command queue and the command was finally posted to the queue. Module/Object information is embedded in the response for tracking purpose. Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S. Miller <davem@davemloft.net>
