fixing out of order first fragment processing?

Hi,
This is one of those obscure, yet well known issues in FreeBSD,
some network stacks, like Linux, send the udp/icmp fragment
first (if multiple frags -- in reverse order), then the orginal
packet with the header.
In -current, we still cannot process this simple fragged icmp-echo
request from a Linux host. For example, 'ping -c 1 -s 1500 <freebsd ip>'.
FreeBSD discards the frag(s) and when it sees the initial packet with
header waits for the frags.
So two questions:
1. is there a gnats pr? I tried various searches with no success.
2. are there workarounds/patches?
