Brilliant! I was confused that on GNU/Linux the rtl8169 and e1000 drivers did not hinder the capture of headers with checksum properly filled in, but on GNU/kFreeBSD the driver bge for Tigon really does offload the computation. Thus I now know that the AH+ESP-transport is receiving and transmitting impeccably correct packages. All is well. Thanks for the illuminating reminder!
