on the 7th of January 2014 ths patch was applied:

[PATCH v2] net: Do not enable tx-nocache-copy by default

In the Sheevaplug (ARM Feroceon 88FR131 from Marvell) this made packets to be
sent corrupted. I think this machine has something special about the cache.

Enabling back this tx-nocache-copy (as it used to be before the patch) the
transfers work fine again. I think that most people, encountering this problem,
completely disable the tx offload instead of enabling back this setting.

Is this an ARM kernel problem regarding this platform?
