2017-08-07asix: Fix small memory leak in ax88772_unbind()Dean Jenkins
When Ethernet frames span mulitple URBs, the netdev buffer memory pointed to by the asix_rx_fixup_info structure remains allocated during the time gap between the 2 executions of asix_rx_fixup_internal(). This means that if ax88772_unbind() is called within this time gap to free the memory of the parent private data structure then a memory leak of the part filled netdev buffer memory will occur. Therefore, create a new function asix_rx_fixup_common_free() to free the memory of the netdev buffer and add a call to asix_rx_fixup_common_free() from inside ax88772_unbind(). Consequently when an unbind occurs part way through receiving an Ethernet frame, the netdev buffer memory that is holding part of the received Ethernet frame will now be freed.

2016-08-31net: asix: Add in_pm parameterRobert Foss
From: Freddy Xin <freddy@asix.com.tw> In order to R/W registers in suspend/resume functions, in_pm flags are added to some functions to determine whether the nopm version of usb functions is called. Save BMCR and ANAR PHY registers in suspend function and restore them in resume function. Reset HW in resume function to ensure the PHY works correctly.

2015-10-05asix: Rename remaining and size for clarityDean Jenkins
The Data header synchronisation is easier to understand if the variables "remaining" and "size" are renamed. Therefore, the lifetime of the "remaining" variable exists outside of asix_rx_fixup_internal() and is used to indicate any remaining pending bytes of the Ethernet frame that need to be obtained from the next socket buffer. This allows an Ethernet frame to span across multiple socket buffers. "size" is now local to asix_rx_fixup_internal() and contains the size read from the Data header 32-bit word. Add "copy_length" to hold the number of the Ethernet frame bytes (maybe a part of a full frame) that are to be copied out of the socket buffer.

2014-01-16drivers/net: delete non-required instances of include <linux/init.h>Paul Gortmaker
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. This covers everything under drivers/net except for wireless, which has been submitted separately. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: David S.

2013-12-06usb: Fix FSF address in file headersJeff Kirsher
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 <http://www.gnu.org/licenses/> so that we do not have to keep updating the header comments anytime the address changes.

2013-01-18net: asix: handle packets crossing URB boundariesLucas Stach
ASIX AX88772B started to pack data even more tightly. Packets and the ASIX packet header may now cross URB boundaries. To handle this we have to introduce some state between individual calls to asix_rx_fixup(). Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-07-19asix: Rework reading from EEPROMChristian Riesch
The current code for reading the EEPROM via ethtool in the asix driver has a few issues. It cannot handle odd length values (accesses must be aligned at 16 bit boundaries) and interprets the offset provided by ethtool as 16 bit word offset instead as byte offset. The new code for asix_get_eeprom() introduced by this patch is modeled after the code in drivers/net/ethernet/atheros/atl1e/atl1e_ethtool.c and provides read access to the entire EEPROM with arbitrary offsets and lengths.

The Asix AX88172A is a USB 2.0 Ethernet interface that supports both an internal PHY as well as an external PHY (connected via MII).
