Change details: - Add debugfs support to obtain firmware trace, saved firmware trace on an IOC crash, driver info and read/write to registers. - debugfs hierarchy: bna/pci_dev:<pci_name> where the pci_name corresponds to the one under /sys/bus/pci/drivers/bna - Following are the new debugfs entries added: fwtrc: collect current firmware trace. fwsave: collect last saved fw trace as a result of firmware crash. regwr: write one word to chip register regrd: read one or more words from chip register. drvinfo: collect the driver information.

Change details: - Add a callback in the BNA, which is called before sending FW command to stop RxQs. After this callback is called, driver should not post anymore Rx buffers to the RxQ. This addresses a small window where driver posts Rx buffers while FW is stopping/has stopped the RxQ. - Registering callback function, rx_stall_cbfn, during bna_rx_create. Invoking callback function, rx_stall_cbfn, before sending rx_cfg_clr command to FW - Bnad_cb_rx_stall implementation - set a flag in the Rxq to mark buffer posting disabled state. While posting buffers check for the above flag. Signed-off-by: NGurunatha Karaje <gkaraje@brocade.com> Signed-off-by: NRasesh Mody <rmody@brocade.com> Signed-off-by: NDavid S.

Change details: - Add tx_skb counters and NAPI debug counters to ethtool stats. - Add rlb stats strings to bnad_net_stats_strings{} array. rlb_stats field was added to struct bfi_enet_stats {} but the corresponding name structure array for ethtool was not initialized with right strings, even though the actual name structure array got expanded. This caused a NULL pointer violation and a crash when doing ehtool -S <if_name>. - Modify dim timer stop logic to make it dependent on cfg and run flags - While setting the ring parameter restore the rx, vlan configuration and set rx mode - Indentation fix Signed-off-by: NGurunatha Karaje <gkaraje@brocade.com> Signed-off-by: NRasesh Mody <rmody@brocade.com> Signed-off-by: NDavid S.

Change details: - Add bnad_pci_unmap_skb() API to unmap skb from transmit path and update the unmap index. Add more checks for illegal skbs in transmit path. Add tx_skb counters for dropped skbs. - The unmap_cons index used in bnad_free_txbufs() is incorrectly declared as u16. It quickly wraps around and accesses null sk_buff ptr. So using u32 to handle unmap_array. - Disable and enable interrupts from the same polling context to prevent reordering in Rx path. - Add Rx NAPI debug counters. - Make NAPI budget check more generic. - Modify dim timer stop logic to make it dependent on cfg and run flags - Handle reduced MSI-X vectors case in bnad_enable_msix. - Check for single frame TSO skbs and send them out as non-TSO. - Put memory barrier after bna_txq_prod_indx_doorbell().

Change details: - Remove unnecessary ccb check from bnad_poll_cq - Add bnad pointer to rx_ctrl structure, so that bnad can be accessed directly from rx_ctrl in the NAPI poll routines, even if ccb is NULL - Validate ccb before referencing to it in bnad_msix_rx and bnad_napi_poll_rx - Fix the order of NAPI init / uninit in Tx / Rx setup / teardown path: a. Kill bnad tx free tasklet ahead of call to bna_tx_destroy() b. Call NAPI disable only after call to Rx free_irq(). This makes sure Rx interrupt does not schedule a poll when NAPI is already disabled - NAPI poll runs before the h/w has completed configuration. This causes a crash. Delay enabling NAPI till after bna_rx_enable(). Split NAPI initialization into 2 steps, bnad_napi_init() & bnad_napi_enable().

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.
