[ipxe-devel] undionly.kpxe fails to DHCP on QLogic 8242

[Buck Huppmann]

Hi

I tried putting this up on the ``general'' forum, but my post disap-
peared into the ether somewhere (just like my iPXE's DHCP requests),
so this omits most of the details there and just reports the one half-
way technical finding i made that might be of interest to the devel-
oper audience

PXE loads undionly.kpxe and initializes devices but then the DHCP
request fails.  I notice the below tcpdump -VX frame seems to be the
one and only peep out of the card before iPXE quits.  (There is no
response from the DHCP server.)  Note that it looks like it has bo-
gus 802.2 LLC header, and then what tcpdump prints as the frame PDU
load looks like a good Ethernet DHCP frame, so it seems like the
UNDI on this QLogic card is trying to encapsulate the raw buffer
that undidev_transmit is putting in undi_transmit.TDB

Any idea?

(In the below, 00:0e:1e:06:f0:b8 is the correct MAC of the QLogic NIC;
b5:01:54:14:d9:5a is garbage, as far as i know; ditto the length, DSAP,
SSAP, etc., but then you can see the ffff ffff ffff 000e 1e06 f0b8 0800
... looks like a good DHCP frame)
