* tg3: Add MDIO bus address assignmentsMatt Carlson2009-09-02
| | | | | | | | | | | | The 5717 is a dual port chip that has a shared MDIO bus design. While it is impossible for one function to interface with the wrong phy, that function still needs to know which MDIO bus address to use when interfacing with its own phy. This patch adds code to determine which MDIO bus address to use. Signed-off-by: Matt Carlson <mcarlson@broadcom.com> Reviewed-by: Benjamin Li <benli@broadcom.com> Signed-off-by: David S.

* tg3: Assign rx ret producer indexes by vectorMatt Carlson2009-09-02
| | | | | | | | | | | | | When RSS is enabled, the status block format changes slightly. The "rx_jumbo_consumer", "reserved", and "rx_mini_consumer" members get mapped to the other three rx return ring producer indexes. This patch introduces a new per-interrupt member which identifies which location in the status block a particular vector should look for return ring updates.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bartlomiej Zolnierkiewicz reported an atomic order-6 allocation failure for ipw2200 firmware loading in kernel 2.6.30. High order allocation is likely to fail and should always be avoided. The patch fixes this problem by replacing the original order-6 pci_alloc_consistent() with an array of order-1 pages from a pci pool. This utilized the ipw2200 DMA command blocks (up to 64 slots). The maximum firmware size support remains the same (64*8K).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NETPOLL API requires that interrupts remain disabled in netpoll_send_skb(). The use of "A functions set" in the NETPOLL API callbacks causes the interrupts to get enabled and can lead to kernel instability. The solution is to use "B functions set" to prevent the irqs from getting enabled while in netpoll_send_skb(). A functions set: local_irq_disable()/local_irq_enable() spin_lock_irq()/spin_unlock_irq() spin_trylock_irq()/spin_unlock_irq() B functions set: local_irq_save()/local_irq_restore() spin_lock_irqsave()/spin_unlock_irqrestore() spin_trylock_irqsave()/spin_unlock_irqrestore() Signed-off-by: Dongdong Deng <dongdong.deng@windriver.com> Acked-by: Matt Mackall <mpm@selenic.com> Signed-off-by: David S.

| * E100: fix interaction with swiotlb on X86.Krzysztof Hałasa2009-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | E100 places it's RX packet descriptors inside skb->data and uses them with bidirectional streaming DMA mapping. Data in descriptors is accessed simultaneously by the chip (writing status and size when a packet is received) and CPU (reading to check if the packet was received). This isn't a valid usage of PCI DMA API, which requires use of the coherent (consistent) memory for such purpose. Unfortunately e100 chips working in "simplified" RX mode have to store received data directly after the descriptor. Fixing the driver to conform to the API would require using unsupported "flexible" RX mode or receiving data into a coherent memory and using CPU to copy it to network buffers. This patch, while not yet making the driver conform to the PCI DMA API, allows it to work correctly on X86 with swiotlb (while not breaking other architectures).

When ibm_newemac slave is shutdown with "ifconfig down", the bonding interface won't detect any link status change because netif_carrier_ok() keeps returning TRUE.

| * drivers/net: fixed drivers that support netpoll use ndo_start_xmit()Dongdong Deng2009-08-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NETPOLL API requires that interrupts remain disabled in netpoll_send_skb(). The use of spin_lock_irq() and spin_unlock_irq() in the NETPOLL API callbacks causes the interrupts to get enabled and can lead to kernel instability. The solution is to use spin_lock_irqsave() and spin_unlock_restore() to prevent the irqs from getting enabled while in netpoll_send_skb(). Call trace: netpoll_send_skb() { -> local_irq_save(flags) ---> dev->ndo_start_xmit(skb, dev) ---> spin_lock_irq() ---> spin_unlock_irq() *******here would enable the interrupt. ... -> local_irq_restore(flags) } Signed-off-by: Dongdong Deng <dongdong.deng@windriver.com> Signed-off-by: Jason Wessel <jason.wessel@windriver.com> Acked-by: Bruce Ashfield <bruce.ashfield@windriver.com> Acked-by: Matt Mackall <mpm@selenic.com> Signed-off-by: David S.
