This patch adds NAPI support to the qeth layer 2 and layer 3 discipline. It is important to understand that we can not enable/disable IRQs as usual, we have to use the corresponding new QDIO interface. Also to not overdraw the budget we have to stop and restart buffer processing at any point during processing a bulk of QDIO buffers. Having the driver NAPI enabled it is possible to turn on GRO for the layer 3 discipline. Signed-off-by:

Since the claw code calls ccwgroup_remove_ccwdev(), we need to make sure CCWGROUP is enabled when CLAW is enabled. Otherwise we hit fun undefined references at build time: ERROR: "ccwgroup_remove_ccwdev" [drivers/s390/net/claw.ko] undefined! ERROR: "ccwgroup_probe_ccwdev" [drivers/s390/net/claw.ko] undefined!

Extend the qdio API to allow polling in the upper-layer driver. This is needed by qeth to use NAPI. To use the new interface the upper-layer driver must specify the queue_start_poll(). This callback is used to signal the upper-layer driver that is has initiative and must process the inbound queue by calling qdio_get_next_buffers(). If the upper-layer driver wants to stop polling it calls qdio_start_irq(). Since adapter interrupts are not completely stoppable qdio implements a software bit QDIO_QUEUE_IRQS_DISABLED to safely disable interrupts for an input queue. The old interface is preserved and will be used as is by zfcp. Signed-off-by:

Several users report issues with 32-bit adapters when plugged into PCI slots in machines with >= 4GB ram. In particular AMD systems with HyperTransport to PCI bridges seem to trigger the issue, but it isn't limited to only them. This issue is not easily reproducible here, yet still continues to occur in the field. For e1000 on PCI devices, just disable DMA addresses over the 4GB boundary when in PCI (not PCI-X) mode, to prevent the issue from continuing to pop up. The performance impact for this is negligible. The code was refactored to move the init of the hw struct to its own function. This allows the init to be called very early in probe, which then allows using hw-> members for this fix. A slight refactor to the DMA mask code was done for minor correctness based on the instructions in DMA-API-HOWTO. Signed-off-by:

Casts __kernel to __user pointer require __force markup, so add it. Also sock_get/setsockopt() takes @optval and/or @optlen arguments as user pointers but were taking kernel pointers, use new variables 'uoptval' and/or 'uoptlen' to fix it.

This patch introduces cx82310_eth driver - driver for USB ethernet port of ADSL routers based on Conexant CX82310 chips. Such routers usually have ethernet port(s) too which are bridged together with the USB ethernet port, allowing the USB-connected machine to communicate to the network (and also internet through the ADSL, of course). This is my first driver, so please check thoroughly. As there's no protocol documentation, it was done with usbsnoop dumps from Windows driver, some parts (the commands) inspired by cxacru driver and also other usbnet drivers. The driver passed my testing - some real work and also pings sized from 0 to 65507 B. The only problem I found is the ifconfig error counter. When I return 0 (or 1 but empty skb) from rx_fixup(), usbnet increases the error counter although it's not an error condition (because packets can cross URB boundaries). Maybe the usbnet should be fixed to allow rx_fixup() to return empty skbs (or some other value, e.g. 2)? The USB ID of my device is 0x0572:0xcb01 which conflicts with some ADSL modems using cxacru driver (they probably use the same chipset but simpler firmware). The modems seem to use bDeviceClass 0 and iProduct "ADSL USB MODEM", my router uses bDeviceClass 255 and iProduct "USB NET CARD". The driver matches only devices with class 255 and checks for the iProduct string during init. I already posted a patch for the cxacru driver to ignore these devices. Signed-off-by:

Yaniv Rosner authored
Make the needed changes for the new scheme especially around PHY initialization, and link detection. - The get_emac_base function was changed to enable setting different MAC access setting for each PHY based of external configuration. - As a part of the dual-media preparation, the save_spirom_version was modified to accept a PHY specific version address to be saved in the shmem. This will enable to save more than single spirom version in different locations. - The test_link function was changed also as a preparation for the dual-media upcoming changes - Duplicate initialization logic was removed from the link_setting_status and link_initialize functions Signed-off-by:

Yaniv Rosner authored
Move the code into PHY oriented functions, and for that a new structure is defines for each PHY which contain PHY properties and its own functions. This also enables to encapsulate all PHY specific operations into the PHY functions. During initialization, the PHYs will be probed by the "bnx2x_phy_probe" function to detect which PHYs exist on-board, and configure them accordingly. Note that the ext_phy_reset implementation was incorporated in the ext_phy_init since it is actually part of the PHY initialization procedure. Signed-off-by:

The function has an unsigned return type, but returns a negative constant to indicate an error condition. The result of calling the function is always stored in a variable of type (signed) int, and thus unsigned can be dropped from the return type.

This showed up in my audit because we use strcpy() to copy "ds" into a 32 character buffer inside the isdn_tty_dial() function. But it turns out that we only ever use the first 32 characters so it's OK. I have changed the declaration to make the static checkers happy. Signed-off-by:
