2009-04-02tcp: miscounts due to tcp_fragment pcount resetIlpo Järvinen
It seems that trivial reset of pcount to one was not sufficient in tcp_retransmit_skb. Multiple counters experience a positive miscount when skb's pcount gets lowered without the necessary adjustments (depending on skb's sacked bits which exactly), at worst a packets_out miscount can crash at RTO if the write queue is empty! Triggering this requires mss change, so bidir tcp or mtu probe or like.

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

2009-04-02net: allow multiple dev per napi with GROStephen Hemminger
GRO assumes that there is a one-to-one relationship between NAPI structure and network device. Some devices like sky2 share multiple devices on a single interrupt so only have one NAPI handler. Rather than split GRO from NAPI, just have GRO assume if device changes that it is a different flow. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

2009-04-02r8169: reset IntrStatus after chip resetKarsten Wiese
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.

2009-04-02Neterion: New driver: register set - vxge-reg.hRamkrishna Vepa
- 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.

2009-04-02Neterion: Driver help fileRamkrishna Vepa
- vxge driver help text file. - No change from previous submission. - Changes in previous submissions - Removed the performance tuning section with instructions to disable time stamps and change sysctl settings - Reported by Dave Miller General clean up. - Removed tx/rx_pause, exec_mode, tx_steering_type, rx_steering_type, gro, intr_type, rx & tx max_indicate_pkts and exec_mode loadable parameters. The driver default settings work well in most if not all cases. Another patch to configure these parameters with ethtool will be released in the future - Reported by Stephen Hemminger. - Incorporated following fixes based on comments from Ben Hutchings Removed references to earlier kernel versions. Removed sections that are similar for all drivers - Load/Unload Identifying the adapter/interface Boot time configuration Removed loadable parameter - NAPI - Napi is always enabled. rx_steering_type & ring_blocks - The driver default settings work well in most if not all cases. Another patch to configure these parameters with ethtool will be released in the future. Removed ethtool support section - No need to duplicate ethtool docs here. Removed Known Issue on SUSE 9 - Doesn't apply when using a current kernel. Removed Common Problems section - These don't apply to in-tree modules. Removed Available Downloads section - Not sure this belongs in-tree. Removed Copyright information - This notice doesn't belong in the kernel.

2009-03-31sfc: Call netif_napi_add() before registering our interrupt handlerBen Hutchings
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.
