Yes, you are right.

Before we sent our our patch, we must test it on all covered platforms.


Thanks,

I guess Jim only tested the code on imx6q-fec.  We shouldn't enable it for the other two platforms until it's been tested on them.  As the counter example, although we expect FEC_QUIRK_HAS_CSUM should also work for imx28-fec, if we enable FEC_QUIRK_HAS_CSUM for it, fec driver will just break right way on imx28.
