net: asix: add support for the Sitecom LN-028 USB adapter

2015-02-27T22:12:20+00:00

Just another AX88178-based 10/100/1000 USB-to-Ethernet dongle. This one
shows up in lsusb as: "Sitecom Europe B.V. LN-028 Network USB 2.0 Adapter".

net: USB: Deletion of unnecessary checks before the function call "kfree"

2014-11-21T20:16:10+00:00

The kfree() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

asix: Do full reset during ax88772_bind

2014-11-07T20:30:03+00:00

commit 3cc81d85ee01 ("asix: Don't reset PHY on if_up for ASIX 88772")
causes the ethernet on Arndale to no longer function. This appears to
be because the Arndale ethernet requires a full reset before it will
function correctly, however simply reverting the above patch causes
problems with ethtool settings getting reset.

It seems the problem is that the ethernet is not properly reset during
bind, and indeed the code in ax88772_bind that resets the device is a
very small subset of the actual ax88772_reset function. This patch uses
ax88772_reset in place of the existing reset code in ax88772_bind which
removes some code duplication and fixes the ethernet on Arndale.

It is still possible that the original patch causes some issues with
suspend and resume but that seems like a separate issue and I haven't
had a chance to test that yet.

asix: Don't reset PHY on if_up for ASIX 88772

2014-10-03T22:38:49+00:00

I've noticed every time the interface is set to 'up,', the kernel
reports that the link speed is set to 100 Mbps/Full Duplex, even
when ethtool is used to set autonegotiation to 'off', half
duplex, 10 Mbps.
It can be tested by:
 ifconfig eth0 down
 ethtool -s eth0 autoneg off speed 10 duplex half
 ifconfig eth0 up

Then checking 'dmesg' for the link speed.

net: asix: add missing flag to struct driver_info

2014-02-14T20:47:43+00:00

The struct driver_info ax88178_info is assigned the function
asix_rx_fixup_common as it's rx_fixup callback. This means that
FLAG_MULTI_PACKET must be set as this function is cloning the
data and calling usbnet_skb_return. Not setting this flag leads
to usbnet_skb_return beeing called a second time from within
the rx_process function in the usbnet module.

usb: Fix FSF address in file headers

2013-12-06T17:37:55+00:00

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.

net: asix: Move declaration of ax88172a_info to shared header

2013-08-13T21:13:52+00:00

Ensure that the definition of ax88172a_info matches the declaration seen
by users and silence sparse warnings about symbols without declarations
in the global namespace by moving the declaration into the shared header
asix.h.

USBNET: centralize computing of max rx/tx qlen

2013-07-28T03:10:57+00:00

This patch centralizes computing of max rx/tx qlen, because:

- RX_QLEN()/TX_QLEN() is called in hot path
- computing depends on device's usb speed, now we have ls/fs, hs, ss,
so more checks need to be involved
- in fact, max rx/tx qlen should not only depend on device USB
speed, but also depend on ethernet link speed, so we need to
consider that in future.
- if SG support is done, max tx qlen may need change too

Generally, hard_mtu and rx_urb_size are changed in bind(), reset()
and link_reset() callback, and change mtu network operation, this
patches introduces the API of usbnet_update_max_qlen(), and calls
it in above path.

usb/net/asix_devices: Add USBNET HG20F9 ethernet dongle

2013-02-27T18:10:35+00:00

This USB ethernet adapter was purchased in anodyne packaging
from the computer store adjacent to linux.conf.au 2013 in
Canberra (Australia). A web search shows other recent
purchasers in Lancaster (UK) and Seattle (USA). Just like an
emergent virus, our age of e-commerce and airmail allows
underdocumented hardware to spread around the world instantly
using the vector of ridiculously low prices.

Paige Thompson, infected via eBay, discovered that the HG20F9
is a copy of the Asix 88772B; many viruses copy the RNA of
other viruses. See Paige's work at
.
This patch uses her discovery to update the restructured Asix
driver in the current kernel.

Just as some viruses inhabit seemingly-healthy cells, the
HG20F9 uses the Vendor ID 0x066b assigned to Linksys Inc.
For the present there is no clash of Product ID 0x20f9.
