Subject: [PATCH] efinet: enable hardware filters when opening interface
Exclusive open on SNP will close all existing protocol instances which
may disable all receive filters on interface. Reinstall them after we
opened protocol exclusively.
Also follow UEFI specification recommendation and stop interfaces when
closing them:
Unexpected system errors, reboots and hangs can occur if an OS is loaded
and the network devices are not Shutdown() and Stopped().
Also by: Mark Salter <msalter@redhat.com>
Closes: 45204

From 4fe8e6d4a1279b1840171d8e797d911cd8443333 Mon Sep 17 00:00:00 2001

Subject: [PATCH] efinet: handle get_status() on buggy firmware properly
The EFI spec indicates that get_status() should return the address of the buffer
we passed into transmit to indicate the the buffer was transmitted. However we
have boxes where the firmware returns some arbitrary address instead, which
makes grub think that we've not sent anything. So since we have the SNP stuff
opened in exclusive mode just assume any non-NULL txbuf means that our transmit
occurred properly. This makes grub able to do its networking stuff properly on
our broken firmware. Thanks,
