2011-09-15stmmac: remove the STBus bridge setting from the GMAC code (v3)Giuseppe CAVALLARO
This patch removes a piece of code (actually commented) only useful for some ST platforms in the past. This kind of setting now can be done by using the platform callbacks provided in linux/stmmac.h (see the stmmac.txt for further details).

2011-09-15bna: SKB PCI UNMAP FixRasesh Mody
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.

2011-09-15bna: MBOX IRQ Flag Check after LockingRasesh Mody
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: Gurunatha Karaje <gkaraje@brocade.com> Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S.

2011-09-15bna: Async Mode Tx Rx Init FixRasesh Mody
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: Gurunatha Karaje <gkaraje@brocade.com> Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S.

2011-09-15bna: Ethtool Enhancements and FixRasesh Mody
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: Gurunatha Karaje <gkaraje@brocade.com> Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S.

2011-09-15bna: TX Path and RX Path ChangesRasesh Mody
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().

2011-09-15bna: Interrupt Polling and NAPI Init ChangesRasesh Mody
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().
