I have seen those packets, except the DF and MF flags were both set
and BTW you can recreate those packets by using Microsoft ping with
the following command:
ping -l 1500 (or what ever size you see). Just my .02 worth

The third type of traffic from the attacking machine consisted of
very
large ICMP echo-request packets, all going to the same destination IP
address. The ICMP packet contents consisted entirely of the lowercase
letters 'a' through 'w' repeated many times, e.g.,

  abcdefghijklmnopqrstuvwabcdefghijklmnopqrstuvw...

Anyway, this may mean that some type of WebDAV data-gathering or
exploit capability has been incorporated into a software package that
also compromises machines via SMB. There wasn't direct evidence that
the software package was associated with planned exploitation of the
CA-2003-09 vulnerability via WebDAV, although it may have been. The
ICMP traffic suggests that the software package may have a DoS
capability that's separate from the SMB and WebDAV traffic.
