dm9601: work around tx fifo sync issue on dm962x

2014-01-08T17:42:11+00:00

commit 4263c86dca5198da6bd3ad826d0b2304fbe25776 upstream.

Certain dm962x revisions contain an bug, where if a USB bulk transfer retry
(E.G. if bulk crc mismatch) happens right after a transfer with odd or
maxpacket length, the internal tx hardware fifo gets out of sync causing
the interface to stop working.

Work around it by adding up to 3 bytes of padding to ensure this situation
cannot trigger.

This workaround also means we never pass multiple-of-maxpacket size skb's
to usbnet, so the length adjustment to handle usbnet's padding of those can
be removed.

dm9601: fix reception of full size ethernet frames on dm9620/dm9621a

2014-01-08T17:42:11+00:00

commit 407900cfb54bdb2cfa228010b6697305f66b2948 upstream.

dm9620/dm9621a require room for 4 byte padding even in dm9601 (3 byte
header) mode.

[ Upstream commit bf0ea6380724beb64f27a722dfc4b0edabff816e ]

Pass-all-multicast is controlled by bit 3 in RX control, not bit 2
(pass undersized frames).

USB: convert drivers/net/* to use module_usb_driver()

2011-11-18T17:44:20+00:00

This converts the drivers in drivers/net/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

ethtool: Call ethtool's get/set_settings callbacks with cleaned data

2011-04-29T21:01:30+00:00

This makes sure that when a driver calls the ethtool's
get/set_settings() callback of another driver, the data passed to it
is clean. This guarantees that speed_hi will be zeroed correctly if
the called callback doesn't explicitely set it: we are sure we don't
get a corrupted speed from the underlying driver. We also take care of
setting the cmd field appropriately (ETHTOOL_GSET/SSET).

This applies to dev_ethtool_get_settings(), which now makes sure it
sets up that ethtool command parameter correctly before passing it to
drivers. This also means that whoever calls dev_ethtool_get_settings()
does not have to clean the ethtool command parameter. This function
also becomes an exported symbol instead of an inline.

All drivers visible to make allyesconfig under x86_64 have been
updated.

drivers/net/usb: Use kmemdup

2010-05-18T00:44:48+00:00

Use kmemdup when some other buffer is immediately copied into the
allocated region.

A simplified version of the semantic patch that makes this change is as
follows: (http://coccinelle.lip6.fr/)

// 
@@
expression from,to,size,flag;
statement S;
@@

-  to = \(kmalloc\|kzalloc\)(size,flag);
+  to = kmemdup(from,size,flag);
   if (to==NULL || ...) S
-  memcpy(to, from, size);

dm9601: fix phy/eeprom write routine

2010-05-03T22:26:30+00:00

Use correct bit positions in DM_SHARED_CTRL register for writes.

Michael Planes recently encountered a 'KY-RS9600 USB-LAN converter', which
came with a driver CD containing a Linux driver. This driver turns out to
be a copy of dm9601.c with symbols renamed and my copyright stripped.
That aside, it did contain 1 functional change in dm_write_shared_word(),
and after checking the datasheet the original value was indeed wrong
(read versus write bits).

On Michaels HW, this change bumps receive speed from ~30KB/s to ~900KB/s.
On other devices the difference is less spectacular, but still significant
(~30%).
