From 8826cedd1df8cf82da69dce55e837f6498208ce9 Mon Sep 17 00:00:00 2001 From: Alexander Graf <agraf@suse.de> Date: Thu, 15 Mar 2018 17:28:10 +0100 Subject: [PATCH] efi_loader: Fix network DP with DM_ETH When CONFIG_DM_ETH is set, we assemble the device path properly with a full device hierarchy. Our helper function dp_fill() even put the MAC node itself in it for us. However, for non-DM compatibility we also have code in that added the MAC node manually. That code now runs on top of the existing MAC node: Handle 0x3db2f6b0 /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ] /USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1) /MacAddr(b8:27:eb:e1:81:47,57)/EndEntire We obviously don't need the additional node and in fact, grub chokes on it and fails to match the DP against the ethernet device node. So this patch moves the additional MAC node into the non-DM code path: Handle 0x3db3fde0 /HardwareVendor(e61d73b9-a384-4acc-aeab-82e828f3628b)[0: ] /USBClass(0,0,9,0,0)/USBClass(424,9514,9,0,2)/MacAddr(b8:27:eb:e1:81:47,1) /EndEntire While at it, we also mark the non-DM MAC node as ethernet.
