HARD_TX_LOCK micro is a nice aggregation that could be used in other spots. move it to netdevice.h Also makes sure the previously superflous cpu arguement is used.

The bulk of the CIPSO option parsing/processing in the cipso_v4_sock_getattr() and cipso_v4_skb_getattr() functions are identical, the only real difference being where the functions obtain the CIPSO option itself. This patch creates a new function, cipso_v4_getattr(), which contains the common CIPSO option parsing/processing code and modifies the existing functions to call this new helper function.

For the operations get-tx-csum get-sg get-tso get-ufo the default ethtool_op_xxx behavior is fine for all drivers, so we permit op==NULL to imply the default behavior. This provides a more uniform behavior across all drivers, eliminating ethtool(8) "ioctl not supported" errors on older drivers that had not been updated for the latest sub-ioctls. The ethtool_op_xxx() functions are left exported, in case anyone wishes to call them directly from a driver-private implementation -- a not-uncommon case. Should an ethtool_op_xxx() helper remain unused for a while, except by net/core/ethtool.c, we can un-export it at a later date.

We now have struct net_device_stats embedded in struct net_device, and the default ->get_stats() hook does the obvious thing for us. Run through drivers/net/* and remove the driver-local storage of statistics, and driver-local ->get_stats() hook where applicable. This was just the low-hanging fruit in drivers/net; plenty more drivers remain to be updated.

It's been a useless no-op for long enough in 2.6 so I figured it's time to remove it.

- Code Optimization of s2io_isr function. - Isr check using per device napi variable instead of driver global. - Reduced from 3 to 1 if condition before check for processing packet receive packets. - Implemented Jeff's comment to use synchronize_irq. Removed the isr_cnt variable as it became redundant. - One time de assert the interrupts by writing all F's to the general_int_mask register instead of de asserting by clearing the source of interrupts with multiple writes which causes loss of interrupts (race conditions). It is entirely possible that before the driver has a chance to mask the asserted alarm bit, another alarm/traffic interrupt bit gets asserted as well. In this case Herc will keep the INTA line asserted and the bridge will not send a new Assert_INTA message upstream.

- 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.

- 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.

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.

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.

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: Auke Kok <auke-jan.h.kok@intel.com> Signed-off-by: Ayyappan Veeraiyan <ayyappan.veeraiyan@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: David S.

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.

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.

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.
