I don't know how you are switching input relative to capture. Fields mixing from other frames can also be DMA overflows in the capture. In my opinion, if you have a working Linux version that you are happy with, I suspect it will take more time tweeking the FreeBSD driver than you want to spend. If you want to make some serious updates to the bktr driver, the project could use a bktr maintainer. --Mark Tinguely.
