Package: src:linux Version: 3.2.41-2 Severity: wishlist Tags: patch Dear Maintainer, The ax88197_178a USB 3.0 Gigabit ethernet adapter driver was merged upstream with commit e2ca90c2 (included in 3.9-rc2). It adds support for newer USB 3.0/2.0 Gigabit Ethernet adapters using Asix chipsets. The attached patches (including a backport of e2ca90c2) add the driver to 3.2.41. The bulk of the required changes are due to the introduction of usbnet control functions in 3.8 which are used by the upstream driver. Part of the changes required have been inspired by/copied from the out-of-tree version provided by Asix in [1]. The driver has been tested and seems to be working in order (RX/TX, MTU 4088, ethtool & MII interfaces). Please include the driver in Debian's 3.2 if possible.

Subject: [PATCH 1/5] ax88179_178a: ASIX AX88179_178A USB 3.0/2.0 to gigabit
ethernet adapter driver
This is a resubmission.
Added kfree() in ax88179_get_eeprom to prevent memory leakage.
Modified "__le16 rxctl" to "u16 rxctl" in "struct ax88179_data" and removed pointless casts.
Removed asix_init and asix_exit functions and added "module_usb_driver(ax88179_178a_driver)".
Fixed endianness issue on big endian systems and verified this driver on iBook G4.
Removed steps that change net->features in ax88179_set_features function.
Added "const" to ethtool_ops structure and fixed the coding style of AX88179_BULKIN_SIZE array.
Fixed the issue that the default MTU is not 1500.
Added ax88179_change_mtu function and enabled the hardware jumbo frame function to support an
MTU higher than 1500.
Fixed indentation and empty line coding style errors.
The _nopm version usb functions were added to access register in suspend and resume functions.
Serveral variables allocted dynamically were removed and replaced by stack variables.
ax88179_get_eeprom were modified from asix_get_eeprom in asix_common.
This patch adds a driver for ASIX's AX88179 family of USB 3.0/2.0
to gigabit ethernet adapters. It's based on the AX88xxx driver but
the usb commands used to access registers for AX88179 are completely different.
This driver had been verified on x86 system with AX88179/AX88178A and
Sitcomm LN-032 USB dongles.

Subject: [PATCH 3/5] ax88179_178a: ax88179_write_cmd_async using a control
URB
ax88179_write_cmd_async() uses usbnet_write_cmd_async(), which was introduced
in 3.8. Rewrite ax88179_write_cmd_async() to use a control URB instead.
This patch is based on the driver version 1.4.0 by Asix but refactored to minimize
changes. Also added the URB_FREE_BUFFER transfer flag to have usb_free_urb()
automatically free up the buffer upon completion (original driver lacked this).

Subject: [PATCH 4/5] ax88179_178a: remove disable_hub_initiated_lpm
usb_driver flag
The disable_hub_initiated_lpm usb_driver flag was introduced in kernel version
3.5 and set to 1 for all existing devices. There is no equivalent functionality
in 3.2, so the flag must be removed.
