How do you patch a driver?

[Foo Ji-Haw]

Thanks for the tip. Will take a look at it.

I know that OE6 is a bit dated, but I use IMAP heavily, and Thunderbird
likes to hang when it fails to get a connection with the IMAP server, and I
can't restart the connection short of restarting the app.

I have another question, which I hope you can help me with. This is quite
important to me:

I am trying to put set up port forwarding on my machine. So far the usual
'add allow' and 'add deny' rules work perfectly. The most important rule
which bugs me is the 'add fwd' rule, which the snippet below shows:
ipfw add fwd 192.168.0.4,80 tcp from 10.10.10.0 to any 80

When I try to enter this on the command line, I get the following error:
 ipfw: getsockopt(IP_FW_ADD): Invalid Argument

I tried researching the web. Some mention the error only upon recompiling
kernels. But I am using the standard 5.4 product release as-is. My firewall
rules in rc.conf are as follows:
firewall_enable="YES"
firewall_logging="YES"

I also have this line in dmesg:
 ipfw2 initialized, divert disabled, rule-based forwarding disabled, default
to deny, logging disabled

I see that 'rule-based forwarding' is disabled. Is this what caused the
error? How can I enable it? I can't find the details on the Handbook.

Thanks for your help Subhro!
