[syslinux] EFI/PXE boot on Oracle X5-2

[Michael Glasgow]

Hello all,

I am seeing the same symptoms described here by Holger Baust on
5-Feb-2015.  The only differences in our setups that I can see are
that Mr. Baust claimed to be using HP DL380p Gen9, whereas I'm on
an Oracle X5-2, and Mr. Baust claimed to be using vlan tagging,
while I am not.

My capture looks similar too (attached).  This was done with the filter
suggested by Gene Cumm on 7-Feb:

tcpdump -i bond0 -s0 -w /tmp/pxe.pcap '(ether host 00:10:e0:71:ec:78) or ((udp port 67 or udp port 68) and (udp[36:4] = 0x0010e071 ) and (udp[40:2] = 0xec78))'

Tried with both 6.03 official binaries and also tried building from HEAD
at http://git.zytor.com/syslinux/syslinux.git, as of today (11-Jun-2015).
Same results in both cases.  The pcap is from the latter attempt.

Hope this is useful,
