What a load of CYA crap.  “Sometimes the packet is invalid; it must be a layout problem!  Or maybe Alpha Particles!”  That “CRCError” is am actual ethernet packet CRC error, as far as I can tell.  While those are supposed to be pretty rare in modern real ethernets

You can try just dropping the packet.  They seem to be assuming “the hardware is in a weird state, we’d better reset everything”, and I don’t think that’s true of all of the errors.  A more complete fix might be to separate out the individual errors, count them, and only do the reset when there is “unacceptable frequency of an error.”
