I've upgraded CPU to rev2.1, board rev0.3.
Applied 5/5 patches onto paulus/powerpc.git at e403149c92a. Here is
the results:
If I use -rxid, then geth not able to transmit anything.
With -txid geth not able to receive anything.
With just -id everything works fine though...
Maybe there should be another condition, in addition to cpu rev2.1?

thanks for testing this. I tested these patches on a "pilot assy 0.3".

the errata simply states 'pilot boards', but we can probably modify
u-boot to look at the cpu rev and the board rev (BCSR 12).
My bcsr12 looks like:
=> md.b f800000c 1
f800000c: 10 .
what is yours?
If it's something like 0x03, the u-boot patch will probably look like:
if ((bcsr[12] == 0x10) &&
(immr->sysconf.spridr == SPR_8360_REV21 ||
immr->sysconf.spridr == SPR_8360E_REV21))
/* if phy-connection-type is "rgmii-id", set it to "rgmii-rxid" */
...
but these linux patches would remain the same (the clk and data delay
settings for the UCC's are still valid; it's just the PHY config
that is triggering your problem from what I can tell).

Yup, most likely this is not UCC specific, but PHY. For some reason
delays making harm here...

hmm..
Net: UEC: PHY is Marvell 88E11x1 (1410cc2)
I have jumper JP1 set to 3.3V.
can you send me your:

f8000010: 05 07 05 15 11 .....
and maybe try the following on top of these 5 patches (to specify rgmii
mode in the bcsr's):
diff --git a/arch/powerpc/platforms/83xx/mpc836x_mds.c b/arch/powerpc/platforms/83xx/mpc836x_mds.c

And today I was unable to reproduce yesterday's behaviour. Your
patches works fine, with sixth patch and without it. With -rxid
and with just -id.
Though, after few resets I hit on that:
- - - -
U-Boot 1.3.0-rc3-g281df457-dirty (Nov 6 2007 - 18:19:35) MPC83XX
Reset Status: External/Internal Soft, External/Internal Hard
CPU: e300c1, MPC8360E, Rev: 21 at 528 MHz, CSB: 264 MHz

SDRAM: 64 MB (local bus)
FLASH: 32 MB

Net: UEC: PHY is Marvell 88E11x1 (1410cc2)

FSL UEC0, FSL UEC1
- - - -
And UCC1 does not work at all. After another reset that message
disappears and it does work again.
So, I think hardware is tricking me in various ways, not your
patches fault.
:-(

excellent. btw, you should be paying a 50% packet loss price by not
going with the -rxid. ping your board with '-q -s 1400 -i 0.01 -c 100'
to notice the difference.

the RGMII bcsr settings survive soft-resets, which confuse u-boot since
it uses GMII mode.
