I had an ER Lite, and hardware offload was re-validating packets. Things would come in as error, and come out the other side still invalid, but validated. And at the time my ISP was sending me a lot of uncorrectable errors. So a lot of services would refuse to run with hardware offload on, because the errors weren't being handled. (with it off, the errors were identified as errors and handled. slow, but accurate). Then the pole outside my house got hit by lightning and fried the thing, and I replaced it with something from mikrotik.
