* USB: serial: do not forward USB specific errors in writeJohan Hovold2011-11-15
| | | | | | | | | | | | | Use usb_translate_errors() to map USB-specific errors to errors appropriate for user space (ENOMEM, ENODEV and EIO) in write. Currently almost all serial drivers simply forward error codes from the stack (e.g. from usb_submit_urb()), but these codes often have different meanings in user-space. Doing the mapping in usb-serial core simplifies driver code and allows for more consistent error reporting.

* USB: Add optional match for interface class to dynamic ID facilityJosua Dietze2011-11-15
| | | | | | | | | | | | | | | | When adding the ID of a composite device dynamically to a driver, all hitherto unbound interfaces are bound to this driver regardless of their class, which may not be intended. The patch adds the option to tell the targeted interface class to a driver via the "new_id" attribute, in addition to the device ID. Also, it appends the ABI documentation accordingly. Example: $ echo "1234 2a2a ff" >/sys/bus/usb-serial/drivers/option1/new_id will bind only vendor-specific interfaces to the 3G driver.

* USB: ehci: report Data Buffer Error in debug modeVikram Pandita2011-11-14
| | | | | | | | | | | | | | | | | | | | Data Buffer Error as per spec section 4.15.1.1.2 results when there is Underrun or Overrun condition. This error is considered non-fatal and never gets reported. Its a very good indication on things going wrong at system level, like running memory at much slower speed. This is a good error to flag allowing system level corrections. An issue was found with OMAP4460 board where DDR had to be run at full speed and this logging helped.

* USB: Remove the SAW_IRQ hcd flagAlan Stern2011-11-14
| | | | | | | | | | | | | | | The HCD_FLAG_SAW_IRQ flag was introduced in order to catch IRQ routing errors: If an URB was unlinked and the host controller hadn't gotten any IRQs, it seemed likely that the IRQs were directed to the wrong vector. This warning hasn't come up in many years, as far as I know; interrupt routing now seems to be well under control. Therefore there's no reason to keep the flag around any more.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rx byte count was off; instead use the hardware's count. Tx packet count was counting pre-TSO packets; instead count on-the-wire packets. Report hardware dropped frame count as rx_fifo_errors. - The count of transmitted packets reported by the forcedeth driver reports pre-TSO (TCP Segmentation Offload) packet counts and not the count of the number of packets sent on the wire. This change fixes the forcedeth driver to report the correct count. Fixed the code by copying the count stored in the NIC H/W to the value reported by the driver. - Count rx_drop_frame errors as rx_fifo_errors: We see a lot of rx_drop_frame errors if we disable the rx bottom-halves for too long. Normally, rx_fifo_errors would be counted in this case. The rx_drop_frame error count is private to forcedeth and is not reported by ifconfig or sysfs. The rx_fifo_errors count is currently unused in the forcedeth driver. It is reported by ifconfig as overruns. This change reports rx_drop_frame errors as rx_fifo_errors.
