What is the proper syntax for this in /etc/rc.conf?

ifconfig_bge0="inet 192.168.1.1 -txcsum -rxcsum netmask 255.255.255.0"

??

Ironically, this is also recommended under Solaris 10 for the same NIC:

===========================
If you have a bge interface (eg, SunFire V210), then you may have
NAT problems with ipfilter unless you add the following to
/etc/system:

set ip:dohwcksum=0

This turns off hardware checksumming, which is on by default with
bge interfaces.
