Change details: - Found a leak in sk_buff unmapping of PCI dma addresses where boundary conditions are not properly handled in freeing all Tx buffers. Freeing of all Tx buffers is done considering sk_buffs data and fragments can be mapped at the boundary. Signed-off-by:

sk_buff unmap_array grows greater than 65536 (x2) with Tx ring of 65536. Reducing TXQ depth and safe(max) acking of Tx events to 32768 (same as Rx). Add defines for TX and RX queue depths. Signed-off-by:

Change details: - Check the BNAD_RF_MBOX_IRQ_DISABLED flag after acquiring the bna_lock, since checking the flag and executing bna_mbox_handler needs to be atomic. If not, it opens up window where flag is reset when it was checked, but got set while spinning on the lock by the other thread which is actually holding the lock Signed-off-by:

Change details: - Async mode of Tx/Rx queue initialization in BNAD from a task queue context runs into non-unique taskq allocation issues. Get rid of Tx/Rx initialization from task q context - In the attach function, wait for IOC enable, then do Tx/Rx queue initialization. Default BNA attributes are used when IOC enable from attach fails and values are set to: 1 TxQ, 1 RxQ, 1 Unicast MAC, 1 RIT entry Signed-off-by:

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: -

Change details: - Initialize rx_id to 0 for bnad_cleanup_rx - Return -ENOMEM in case if bna_rx_create fails - Count the Rx buffer allocation failures in bnad_alloc_n_post_rxbufs() - Remove unnecessary initialization of using_dac to false in bnad_pci_probe - Release lock if error while doing bna_num_txq_set in bnad_pci_probe Signed-off-by:

Change details: - Print log messages when running with reduced number of MSI-X vectors and when defaulting to INTx mode. - Remove BUG_ONs and header file inclusion that are not needed - Comments addition/cleanup - Unused code cleanup - Add New Line to Print msg in bfa_sm_fault - Formatting fix Signed-off-by:

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(). Signed-off-by: -

Naming changes: rename devid, BNAD_MAX_TXS, BNAD_MAX_RXS, BNAD_MAX_RXPS_PER_RX to device, BNAD_MAX_TX, BNAD_MAX_RX, BNAD_MAX_RXP_PER_RX respectively and change all the references. Macro Fix: Add ioc_isr_mod_set check to bfa_nw_ioc_mbox_regisr macro Signed-off-by:

The functionality of xlist and llist is almost same. This patch replace xlist with llist to avoid code duplication. Known issues: don't know how to test this, need special hardware? Signed-off-by:
