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
