* virtio_net: Set the mac config only when VIRITO_NET_F_MACAlex Williamson2009-04-041-6/+4
| | | | | | | | | | | VIRTIO_NET_F_MAC indicates the presence of the mac field in config space, not the validity of the value it contains. Allow the mac to be changed at runtime, but only push the change into config space with the VIRTIO_NET_F_MAC feature present.

* e1000: fix loss of multicast packetsJesse Brandeburg2009-04-041-8/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | e1000 (and e1000e, igb, ixgbe, ixgb) all do a series of operations each time a multicast address is added. The flow goes something like 1) stack adds one multicast address 2) stack passes whole current list of unicast and multicast addresses to driver 3) driver clears entire list in hardware 4) driver programs each multicast address using iomem in a loop This was causing multicast packets to be lost during the reprogramming process. reference with test program: http://kerneltrap.org/mailarchive/linux-netdev/2009/3/14/5160514/thread Thanks to Dave Boutcher for his report and test program. This driver fix prepares an array all at once in memory and programs it in one shot to the hardware, not requiring an "erase" cycle.

| | | | | | | | | | | | | commit 1577ecef766650a57fceb171acee2b13cbfaf1d3 ("netdev: Merge UCC and gianfar MDIO bus drivers") introduced a regression so that UCC MDIO buses no longer work.

* r8169: reset IntrStatus after chip resetKarsten Wiese2009-04-021-2/+3
| | | | | | | | | | | | | | | | | | | | | Original comment (Karsten): On a MSI MS-6702E mainboard, when in rtl8169_init_one() for the first time after BIOS has run, IntrStatus reads 5 after chip has been reset. IntrStatus should equal 0 there, so patch changes IntrStatus reset to happen after chip reset instead of before. Remark (Francois): Assuming that the loglevel of the driver is increased above NETIF_MSG_INTR, the bug reveals itself with a typical "interrupt 0025 in poll" message at startup. In retrospect, the message should had been read as an hint of an unexpected hardware state several months ago :o( Fixes (at least part of) https://bugzilla.redhat.com/show_bug.cgi?id=460747 Signed-off-by: Karsten Wiese <fzu@wemgehoertderstaat.de> Signed-off-by: Francois Romieu <romieu@fr.zoreil.com> Tested-by: Josep <josep.puigdemont@gmail.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | Impact: Fix Yinghai Lu found one system with 82575EB where, in the kernel that is kexeced, probe igb failed with -2, the reason being that the adapter could not be brought back from D3 by the kexec kernel, most probably due to quirky hardware (it looks like the same behavior happened on forcedeth). Prevent igb from putting the adapter into D3 during shutdown except when we going to power off the system. For this purpose, seperate igb_shutdown() from igb_suspend() and use the appropriate PCI PM callbacks in both of them. Signed-off-by: "Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch takes care of Initialization and configuration steps of Neterion Inc's X3100 Series 10GbE PCIe I/O Virtualized Server Adapter. - Device Initialization. - Verification and setting of device config parameters. - Allocation of Tx FIFO and Rx Ring descriptors (DTR). - APIs to get various type of hw stats - APIs to configure RTS (Receive Traffic Steering) - Changes in this submission - - Include vmalloc header without which a compilation error occured on sparc64, ppc64 and IA64 plaforms. - Fixed compilation warning in register_poll, write32_upper, write32_lower and the special write64 functions on ppc64. - General cleanup - removed redundant includes and defines. - Changes in previous submissions - - Add readq/writeq implementation for the driver for 32 bit systems - reported by Dave Miller. - Incorporated following comments from Ben Hutchings - Start a comment with "/**" to make it a kernel-doc comment. - Use prefix, "__vxge" in front of hw functions to make them globally unique. - Fixed unnecessary clearing members of *channel just before freeing - Use backslashes only for macro definitions and not in multi-line statements. - Used pci_find_capability instead of redefining it. - Used device and revision ids that are already in pdev - no need to read them again. - Used pci_save_state() and pci_restore_state() around resets. - Used udelay and mdelay directly instead of wrapper. - In __vxge_hw_device_register_poll() reset i to 0 after the microsecond delay loop to commence the millisecond delay loop. - Corrected spelling "sapper" - should be "swapper" - Remove too much vertical whitespace. - Replaced magic numbers with appropriate macros - Incorporated following comments from Andi Kleen [andi@firstfloor.org] - Reduced the arguments in functions or refactored them into smaller functions. - Allocate page sized memories used in slow path with vmalloc. - Use asserts where necessary. - Use macros instead of magic numbers. - Use the pci layer code instead of defining own functions - Remove driver wrappers such as xge_hw_device_private_set(). - Fixed sparse warnings.

| | | | | | | | | | | | | | | | | | | | | | | | | - Complete Register map details of Neterion Inc's X3100 Series 10GbE PCIe I/O Virtualized Server Adapter. - No change from previous submission. - Changes in previous submissions - - Incorporated following comments from Ben Hutchings - Use original macros for endian checks - Remove VXGE_OS_PLATFORM_* macros as they are unused. - Converted multiple bVALX macros into single with additional width parameter and renamed it to vxge_bVALn. - Using __packed instead of pragma pack(1) - Added a comment of the use of a hw swapper so driver code is portable (does not have to change the byte order for register access as well as dma operations) on different ENDIAN platforms. - Using the <linux/pci_regs.h> definitions instead of redefing them. - Using the PCI capabilities registers in <linux/pci_regs.h> instead of redefing them.

* sfc: Call netif_napi_add() before registering our interrupt handlerBen Hutchings2009-03-311-4/+3
| | | | | | | | | | | If we use a shared legacy IRQ then our interrupt handler may be called as soon as it is registered even though IRQs are disabled on the NIC. Now that the legacy interrupt handler also checks for event delivery, it may decide to schedule polling in this case. Ensure that the NAPI context is valid but disabled at this point.
