[ipxe-devel] [ipxe] Adoptation of IPv6 from gPXE (#6)

[Brandon Penglase]

Old Thread Resurrection Time!

Ok, so I took your original patch from the first email, and the one
from the one I'm replying to, and combined them into a patch against the
current (as of 10/09/12 @ 21:55 EDT) master. This is attached.

This is working, in that I can do an ifopen, it gets a IP assigned from
via SLAAC. At this point, I've hit two problems.

1. When I try to ping the IPv6 address from another machine, I can
usually get one ping in, then the machine locks up (VMWare VM in this
case). Once I got 3, and then the VM told me the CPU entered a shutdown
state. Also, if it matters, the pings were 100+ms.

2. When I try to chainload to a IPv6 only address (via DNS), I see the
DNS Query, and it gets the response, however at that point, ipxe throws
"Connection Reset (http://ipxe.org/0f0c6039)".

At this point I'm not really sure how to proceed, as I'm not that
familiar with the code. But, at the very least, I figured I would hit
the ML up with the patch against the current master.

Note: needs -p1 when applying.
