ENGR00181358-2: fec: add FEC driver support for MVF

2012-09-12T20:49:43+00:00

Add FEC driver support for MVF.
Update the phyid for micrel ksz8041 phy.

There are several version sz8041 with different phyid. Those id:
0x00221510, 0x00221512, 0x00221513 were found on different version
SER board. So change the mask to 0x00fffff0 to fit the different version.

ENGR00160701 Fix the Micrel PHY driver

2012-01-09T13:03:27+00:00

Received a fix from Micrel to fix their driver. Without this
patch the Micrel PHY does not get recognized during boot

dp83640: use proper function to free transmit time stamping packets

2011-11-11T17:37:18+00:00

commit f5ff7cd1a84caa9545d952a37ac872ccb73825fb upstream.

The previous commit enforces a new rule for handling the cloned packets
for transmit time stamping. These packets must not be freed using any other
function than skb_complete_tx_timestamp. This commit fixes the one and only
driver using this API.

The driver first appeared in v3.0.

dp83640: free packet queues on remove

2011-11-11T17:35:51+00:00

commit 8b3408f8ee994973869d8ba32c5bf482bc4ddca4 upstream.

If the PHY should disappear (for example, on an USB Ethernet MAC), then
the driver would leak any undelivered time stamp packets. This commit
fixes the issue by calling the appropriate functions to free any packets
left in the transmit and receive queues.

The driver first appeared in v3.0.

dp83640: increase receive time stamp buffer size

2011-08-16T01:31:42+00:00

commit 8028837d71ba9904b17281b40f94b93e947fbe38 upstream.

The dp83640 buffers receive time stamps from special PHY status frames,
matching them to received PTP packets in a work queue. Because the timeout
for orphaned time stamps is so long and the buffer is so small, the driver
can drop time stamps under moderate PTP traffic.

This commit fixes the issue by decreasing the timeout to (at least) one
timer tick and increasing the buffer size.

dp83640: drop PHY status frames in the driver.

2011-06-17T03:48:12+00:00

The dp83640 PHY provides time stamp and other information via special
PHY status frames. Previously, the driver decoded the frames and then
let the network stack drop them. This works fine when the PTP messages
come over UDP.

However, when receiving PTP messages via L2 packets, this creates a
problem. The status frames use the official PTP destination MAC address,
and so they are delivered to user space along with the "real" frames,
causing confusion for applications.

This commit fixes the issue by simply dropping the PHY status frames
in the driver.

dp83640: fix phy status frame event parsing

2011-06-17T03:48:12+00:00

If two eternal time stamp events occur at nearly the same time, the
phyter will add an extra word into the status frame. This commit fixes
the parsing code to recognize and skip over the extra word.

ptp: Fix dp83640 build warning when building statically

2011-05-23T20:32:11+00:00

If the dp83640 driver is not built as a module, the
MODULE_DEVICE_TABLE reference to dp83640_tbl nops out.

Since the table isn't referenced elsewhere, it it causes
the following warning:
drivers/net/phy/dp83640.c:1095: warning: ‘dp83640_tbl’ defined but not used

This apparently is common with mdio_device_id table structures,
and is avoided by using __maybe_unused annotation.

ptp: Added a clock driver for the National Semiconductor PHYTER.

2011-05-23T20:10:23+00:00

This patch adds support for the PTP clock found on the DP83640.
The basic clock operations and one external time stamp have
been implemented.
