bge and checksums

Hello!

	I try to use DSNiff with my FreeBSD 5.4-PRE and bge NIC. Unfortunatelly 
it does no work. My supposition is that the root of problem is bad tcp 
checksums (as shown by tcpdump). And DSNiff (and underlaying libnids) 
are checking for checksums. As I undrestand, bge has txcsum flag, so tcp 
stack does not computes checksum itself. Am I right? And may I turn off 
txcsum flag without modifying bge driver?

With respect,
