U-boot might use non-8-byte-aligned addresses for sending data, which the kwgbe_send doesn't accept (bootp does this for me). This patch copies the data to be sent to a temporary buffer if it is non-aligned.
Kirkwood egiga driver may not be the only client for this kind of requirements. Any Ethernet controller using DMA will require aligned data pointer. I would suggest either upper layers should pass the aligned buffer pointers Or this patch should go in net/ethic, so that other drivers can benefit
