Kernel v2.6.32-rc5-1449-g2c33dca
Based on MPC5200B, DDR, no PCI, large flash mode.
Most importantly, has Micrel 8995 managed switch - currently just 
running in the default power on mode as a basic switch.

'git log' shows that we have that commit.

We have a very recent git:
$ git describe
v2.6.32-rc5-1449-g2c33dca

Hmmm. Looks like our fault. Maybe the networking is running slow?

On a previous MPC5200B board, also in large flash mode, we had slow 
networking performance. Denx provided a patch to disable the XLB bus 
snooping:
+ /* Disable (or enable?) BestComm XLB address snooping */
+ out_be32(&xlb->config, in_be32(&xlb->config) | 
MPC5200B_XLB_CONF_BSDIS);

I tried this at the end of mpc52xx_common.c : 
mpc5200_setup_xlb_arbiter(), but no luck.

Any other ideas?
