From 891b3d9051690d0ba39da4eda1d15773ebfee2b6 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Thu, 5 Oct 2017 16:36:02 +0200 Subject: efi_loader: fix efi_net_get_status The returned interrupt status was wrong. As out transmit buffer is empty we need to always set EFI_SIMPLE_NETWORK_TRANSMIT_INTERRUPT. When we have received a packet we need to set EFI_SIMPLE_NETWORK_RECEIVE_INTERRUPT. Furthermore we should call efi_timer_check() to handle events.
