Subject: Re: Bad checksum on bridge with IP options

My thought of calling ip_forward_options to set RR and TS addresses (not 
to mention checksum) is not working out, because skb_rtable returns 
NULL.  I think I'm supposed to call skb_set_dst, but how
I get dst is eluding me.

Leaving broken values in the options, just recalculating the checksum, 
is starting to look very attractive right now, but I'd rather not.

How do I proceed?
