Re: UEFI/PXE: couldn't send network packet

[Anthony Alba]

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).

Does autoconfiguration by DHCP succeed?
