Hi guys,

I work on a Freescale MPC8347 custom board. I ported u-boot-v2014.01 on it. My config is attached.
I ported linux-3.2.52 (long-term). DTS is attached.

linux-3.2.52 being a bit old, I switched to linux-3.10.29 (long-term).
For linux-3.10.29, I use the same DTS.

linux-3.2.52
------------
Ethernet works on both u-boot and linux-3.2.52: i.e. I can ping, and use a rootfs over NFS.
I attached outputs from u-boot, ifconfig, mii-diag and ethtool utilities (mii-ethtool-ifconfig-3.2.52.txt).

linux-3.10.29
-------------
Ethernet is broken: i.e. I can up the link, it says 100/Full-duplex, but I cannot ping anybody.
When I ping the device from my PC, I get "RX interrupts" (eth0_g0_rx) but no "RX bytes".
Because I cannot use NFS, I mounted rootfs from a compressed initramfs.
I attached outputs from u-boot, ifconfig, mii-diag and ethtool utilities (mii-ethtool-ifconfig-3.10.29.txt).
mii-diag dumps the PHY registers. Only one register differs between the two kernels: 0x15
Datasheet says this register is reserved. I have no control over it.

After a week long of trials, I believe the PHY is fine. Problem might come from the gianfar driver.
Which has widely changed between 3.2 and 3.10: 51 patches.

  $ git log --oneline v3.2.52..v3.10.29 drivers/net/ethernet/freescale/gianfar.c | wc -l
  51

I have not "git bisect" the bug, fearing that I would struggle to build the resulting kernel due to
changes in net/ and the driver model.

Hardware 
--------
The architecture is as follows:

+----------------------+
|  MPC8347  +----------+
|           | gianfar  |
|           | ethernet |
|           | TSEC0    |
|           |          |
|           |   +------+      +-------------+
|           |   | MDIO | <--> | BCM5241 PHY |
|           |   |  MII |      | addr:0      |
|           |   +------+      +-------------+
|           +----------+
+----------------------+

MDIO is connected in MII: 4 TX, 4RX, COL, CRS, TXCLK, RXCLK, MDIO, MDC.
Auto-negotiation is disabled by hardware (pull-ups), speed is fixed to 100Mbps and full-duplex.
The PHY lies at address 0.
MDIO link is fine: I can read/write registers on the PHY.

I made several trials, list is not exhaustive:
- switch to Generic PHY driver
- switch to Broadcom BCM5241 PHY driver
- fixed-link = <0 1 100 0 0> in DTS
- stub tbi-phy node in DTS
- stub ethernet1 node (TSEC1) in DTS
- reset the PHY with mii-diag
- remove the interrupt attribute in DTS

I made it work on linux-3.10.29 once, only 3/4 min after bootup. But I couldn't catch why...

Do you guys see what could be wrong in my config?
Or what has changed in linux-3.{4,6,8,10} that could break my ethernet?

thanks,
Emeric

Hi Emeric,

Thanks for the detailed logs.
You may refer to Romeo's issue:
http://permalink.gmane.org/gmane.linux.network/309587

There's this stable fix for the (older) TSEC controllers:
commit 5eaedf31319d5f80eaaee1eec8dd18c0b452f0d1
("gianfar: Add backwards compatible Single Queue mode polling")

that for some reason was not included in kernel 3.10
(but it was included in kernel 3.11).

Hi David,
Can we have this gianfar fix included in kernel 3.10 as well?
Is there anything I can do to help with this?

Thanks and regards,
Claudiu

Hi Claudiu,

This is it. It seems I haven't search enough on the web.

I cherry-picked it on 3.10.29 and it makes the job!

I second this. Thanks Claudiu!
