I'm pretty sure this isn't needed any more. I think this predates the
switch to seabios, and the seabios DSDT table has a DBUG() aml macro
which writes stuff to the seabios debug port (0x402).

The e1000_receive function for the e1000 needs to discard packets longer than
1522 bytes if the SBP and LPE flags are disabled. The linux driver assumes
this behavior and allocates memory based on this assumption.

This patch updates the seabios submodule to commit
b1c35f2b28cc0c94ebed8176ff61ac0e0b377798.
Most important change is that seabios sets the busmaster bit
in the pci config space for the lsi and esp scsi host adapters.
Since commit 1c380f9460 qemu
is strict here and disallows any dma access when the bit is
clear.

The e801 memory sizes in the multiboot structures hard-code the available
low memory to 640. However, the value should not include the size of the
EBDA. Fill the value in the option ROM, getting the size of low memory
from the BIOS.

Commit 0d8d769085 introduced
a regression in virtio-net performance because it looks

To fix, add parameters limiting lookahead, and

- simplify by doing object_dynamic_cast instead of messing with classes

Hotplugging them simply doesn't work, so tag them accordingly to
avoid users trying and then crashing qemu.
For xhci there is nothing fundamental which prevents hotplug from
working, we'll "only" need a exit() function which cleans up
everything properly. That isn't for 1.3 though.
For ehci+uhci+ohci hotplug can't be supported until qemu gains the
capability to hotplug multifunction pci devices.
