dp83640: use proper function to free transmit time stamping packets

2011-11-11T17:44:48+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

2011-11-11T17:43:06+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: reduce driver noise

2011-09-29T04:32:04+00:00

The driver has two warning messages that might be triggered
by normal use cases. When they appear, the messages give the
impression of a never ending series of errors.

This commit changes them to debug messages instead.

net/phy: fix DP83865 phy interrupt handler

2011-08-26T16:48:24+00:00

According to the DP83865 datasheet we need to clear
the interrupt status bit by writing a 1 to the
corresponding bit in INT_CLEAR (2:0 are reserved).

Proposed and tested by Thorsten.

dp83640: increase receive time stamp buffer size

2011-08-08T05:53:22+00:00

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.
