ax88179_178a: fix bonding failure

2014-10-20T04:53:30Z

The following patch fixes a bug which causes the ax88179_178a driver to be incapable of being added to a bond. When I brought up the issue with the bonding maintainers, they indicated that the real problem was with the NIC driver which must return zero for success (of setting the MAC address). I see that several other NIC drivers follow that pattern by either simply always returing zero, or by passing through a negative (error) result while rewriting any positive return code to zero. With that same philisophy applied to the ax88179_178a driver, it allows it to work correctly with the bonding driver. I believe this is suitable for queuing in -stable, as it's a small, simple, and obvious fix that corrects a defect with no other known workaround. This patch is against vanilla 3.17(.0).

Revert "USBNET: ax88179_178a: enable tso if usb host supports sg dma"

2014-03-07T19:48:13Z

This reverts commit 3804fad45411b48233b48003e33a78f290d227c8. This commit, together with commit 247bf557273dd775505fb9240d2d152f4f20d304 "xhci 1.0: Limit arbitrarily-aligned scatter gather." were origially added to get xHCI 1.0 hosts and usb ethernet ax88179_178a devices working together with scatter gather. xHCI 1.0 hosts pose some requirement on how transfer buffers are aligned, setting this requirement for 1.0 hosts caused USB 3.0 mass storage devices to fail more frequently. USB 3.0 mass storage devices used to work before 3.14-rc1. Theoretically, the TD fragment rules could have caused an occasional disk glitch. Now the devices *will* fail, instead of theoretically failing. >From a user perspective, this looks like a regression; the USB device obviously fails on 3.14-rc1, and may sometimes silently fail on prior kernels. The proper soluition is to implement the TD fragment rules for xHCI 1.0 hosts, but for now, revert this patch until scatter gather can be properly supported.

usbnet: remove generic hard_header_len check

2014-02-17T19:35:46Z

This patch removes a generic hard_header_len check from the usbnet module that is causing dropped packages under certain circumstances for devices that send rx packets that cross urb boundaries. One example is the AX88772B which occasionally send rx packets that cross urb boundaries where the remaining partial packet is sent with no hardware header. When the buffer with a partial packet is of less number of octets than the value of hard_header_len the buffer is discarded by the usbnet module. With AX88772B this can be reproduced by using ping with a packet size between 1965-1976. The bug has been reported here: https://bugzilla.kernel.org/show_bug.cgi?id=29082 This patch introduces the following changes: - Removes the generic hard_header_len check in the rx_complete function in the usbnet module. - Introduces a ETH_HLEN check for skbs that are not cloned from within a rx_fixup callback. - For safety a hard_header_len check is added to each rx_fixup callback function that could be affected by this change. These extra checks could possibly be removed by someone who has the hardware to test. - Removes a call to dev_kfree_skb_any() and instead utilizes the dev->done list to queue skbs for cleanup. The changes place full responsibility on the rx_fixup callback functions that clone skbs to only pass valid skbs to the usbnet_skb_return function.

usb: Fix FSF address in file headers

Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL so that we do not have to keep updating the header comments anytime the address changes.
