[PATCH 0/2] Fix register misuse in drivers/net/phy/marvel.c

[Wang Jian]

These 2 patches fixed misuse of register for 88e1111.

Notice: These two patches didn't fix some auto selection problem yet. I
will discuss the problem in seperate email.

It may not be appropriate to post here instead of netdev, but I am using 
powerpc dev board and I think there will be someone here who has board 
to test.

Hi,

The problem I want to fix is:

1. Plug the fiber and start the board in u-boot, the fiber link is 
established, you can transfer data using fiber link;

2. boot the kernel (not fixed one),  when you "ifconfig ethX up" (ethX 
uses 88e1111), the fiber link light goes off, the fiber link is lost;

After apply the patch #1, for the step 2, you can "ifconfig ethX 
w.x.y.z" and fiber link is ok. You can use the fiber link to transfer data.

I my case, the chip is in GMII mode. The patch #2 is obvious but I can't 
test it myself.

BTW, the two patches doesn't fix the problem when you unplug the fiber 
then plug back. That is another problem I have _partially_ fixed by 
patch marvell_read_status().

[PATCH 0/2] Fix register misuse in drivers/net/phy/marvel.c

[Wang Jian]

These 2 patches fixed misuse of register for 88e1111.

The problem can be reproduced in my powerpc dev board.

With fiber plugged, start the board in u-boot, the fiber link is
established and data transfer is ok. Booting into kernel with current
marvell.c implementation, and "ifconfig ethX up", the fiber link is lost.

The #1 patch fixed this.

The #2 patch is obvious but I can't test it myself because the board I
have using 88e1111 in GMII mode.

Notice: These two patches didn't fix some auto selection problem yet. I
will discuss the problem in seperate email.

[PATCH 0/2] Fix register misuse in drivers/net/phy/marvel.c

[Wang Jian]

The following 2 patches fixed misuse of register for 88e1111. I have
tested the patch 1/2. I have no board to test RGMII mode, patch 2/2 is
obvious but not tested.

I have sent email to Andy but get no response.
