UEFI/PXE: couldn't send network packet

UEFI/PXE: couldn't send network packet

Hi,

I have hit a Dell UEFI BIOS (PowerEdge R720 with
Broadcom LAN-on-motherboard 2 x 10GbE 2 x 1GbE) which
loads GRUB by PXE but GRUB itself hits "error: couldn't send network
packet" and cannot download grub.cfg.

GRUB shows 8(!) efinet cards; there are four physical NICs,
each with 2 mac addresses (one for LAN, one for iSCSI offload).
This is  a Broadcom BCM57800.

However efinet0 efinet1 are given the same mac address
similarly for efinet2, efinet3 etc etc instead, the mac addresses should
differ by 1.

The box boots fine with grub-legacy, and an older BIOS/NIC firmware (in
fact that is how I got it to install). After the BIOS/NIC firmware upgrade
the problems started.

net_ls_addrs, net_ls_cards net_ls_routes don't look suspicious (except for
the duplicate mac addresses).

Does autoconfiguration by DHCP succeed?

Yes: DHCP autoconfiguration works but it looks odd: after UEFI, the IP
information is attached to efinet5. If I want to use bootp to try
autoconfiguration, it only works on efinet4.
efinet5 / efinet4 both refer to the same Broadcom NIC, one for LAN, and the
other for iSCSI.
The mac addresses are the same but should actually differ by 1 (as seen in
the BIOS).
