- Added support to poll entire set of device errors and alarams. - A note on how device errors and alarms are handled: - The adapter will automatically recover from uncorrectable ECC errors. Packets containing corrupted data will be dropped (not transmitted) or tagged as invalid before being passed to the host. - The adapter cannot recover from any internal state machine errors. A state machine error requires a device reset. - Any internal error that could potentially result in .store trampling. (undesirable PCI behaviour)is tagged as a "serious error". In such cases the adapter will give up its ability to be a bus master. In this situation the host will still be able to read internal device registers in order to generate an error report. A device reset is necessary to return to normal operation. - In the event of a pcix data parity error, the adapter will automatically disable itself. Adapter_En will automatically transition from '1' to '0' and the adapter will enter its clean-up routine. Once the device has achieved quiescence, an adapter reset should be performed. - Replaced alarm_intr_handler() with s2io_handle_errors(). - Added statistic counters to monitor the alarms. [ Fix warnings wrt. do_s2io_chk_alarm_bit(), Callers pass in an "unsigned long long *" but the function takes a "u64 *" which is different on many 64-bit platforms. -DaveM ] Signed-off-by:

- Added support to unmask entire set of device errors and alarams. Alarm interrupts are generated for a myriad of purposes, ranging from illegal operations or requests to internal state machine errors and uncorrectable data corruption errors. In several cases the adapter can recover gracefully from unexpected events; however, in some cases, a device reset may be necessary. This patch handles alarms generated by all the blocks within the device. The adapter generates the following types of alarms: 1. Link state transitions (local/remote fault) or other link-related problems. 2. Problems with any device peripherals, including the EEPROM, FLASH, etc. 3. Correctable ECC errors (single-bit errors) on internal data structures or frame data. 4. Uncorrectable ECC errors (multi-bit errors) on internal data structures or frame data. 5. State machine errors, which indicate that internal control structures have become corrupted. 6. PCI related errors, including parity errors or illegal transactions. 7. Other unexpected events. - Implemented Jeff's review comments to use do_s2io_write_bits function to avoid duplicate codes. Signed-off-by: -

Currently, the driver only tries up to 5 times (5us) to get the results of a CQ context operation. Testing has shown the chip can take as much as 50us to return the response on SG_CONTEXT_CMD operations. So we up the retry count to 100 to cover high loads. Signed-off-by:

The cxgb3 driver is incorrectly configuring the HW CQ context for CQ's that use overflow-avoidance. Namely the RDMA control CQ. This results in a bad DMA from the device to bus address 0. The solution is to set the CQ_ERR bit in the context for these types of CQs. Signed-off-by:

This patch adds support for the Intel 82598 PCI-Express 10GbE chipset. Devices will be available on the market soon. This version of the driver is largely the same as the last release: * Driver uses a single RX and single TX queue, each using 1 MSI-X irq vector. * Driver runs in NAPI mode only * Driver is largely multiqueue-ready (TM) Changes since 20070803: * removed wrappers for hardware functions * incorporated e1000e-style HW api reorganization code * sparse/checkpatch cleanups, namespace cleanups * driver prints out extra debugging information at load time identifying adapter board number, mac, phy types * removed ixgbe_api.c, ixgbe_api.h, ixgbe_osdep.h * driver update to 1.1.18 * removed ixgbe.txt which contained no useful info anymore [ Integrated napi_struct changes from Auke as well... -DaveM ] Signed-off-by:Ayyappan Veeraiyan <ayyappan.veeraiyan@intel.com> Signed-off-by:

The PS3 virtual network device requires a vlan tag in the sending packet to select the destination device, ethernet port or wireless. As the vlan tag field is in the middle of the passed data, we should insert it into the packet data. To avoid copying much of the packet data, the driver used two tx descriptors for one tx skb; one descriptor was for sending a small static buffer which contained vlan tag and copied header (two mac addresses), one was for the residual data after the vlan field. This patch changes the way to insert the vlan tag. By changing netdev->hard_header_len, we can make the headroom for moving mac address fields in the skb buffer. Then we can send one tx skb with one tx descriptor. This also gives us a tx throughut gain of approx. 20% according to netperf results. Signed-off-by:

Unfortunately there's no timeout for how long a packet can sit on the TX ring after completion before an interrupt is generated, and we want to have a threshold that's larger than one packet per interrupt. So we have to have a timer that occasionally cleans the TX ring even though there hasn't been an interrupt. Instead of setting up a dedicated timer for this, just clean it in the NAPI poll routine instead. [ Resolved conflicts with napi_struct changes... -DaveM ] Signed-off-by:

Move away from using the pci config access functions for simple register access. Our device has all of the registers in the config space (hey, from the hardware point of view it looks reasonable :-), so we need to somehow get to it. Newer firmwares have it in the device tree such that we can just get it and ioremap it there (in case it ever moves in future products). For now, provide a hardcoded fallback for older firmwares.

Use the kernel interfaces for advanced error reporting. This should be cleaner and clear up errors on boot. For those systems with busted BIOS's that don't correctly support mmconfig, advanced error reporting will be disabled. The PCI registers for advanced error reporting start at 0x100 which is too large to be accessed by legacy functions. Signed-off-by:
