One VMD equipped platform has another PCI bridge with PCI ID [8086:a0bc]
that is not already in Ubuntu sauced PCI_DEV_FLAGS_ENABLE_ASPM list.
Link Capability Register shows ASPM L1 supported, but has ASPM Disabled
in Link Control status:
Some platforms have an AHCI controller behind VMD. These platforms are
working correctly except for a case when the AHCI MSI is programmed with
VMD IRQ vector 0 (0xfee00000). When programmed with any other interrupt
(0xfeeNN000), the MSI is routed correctly and is handled by VMD. Placing
the AHCI MSI(s) in the fast-interrupt allow list solves the issue.
This also requires that VMD allocate more than one MSI/X vector and
changes the minimum MSI/X vectors allocated to two.

UBUNTU: SAUCE: net/packet: fix overflow in tpacket_rcv
Using tp_reserve to calculate netoff can overflow as
tp_reserve is unsigned int and netoff is unsigned short.
This may lead to macoff receving a smaller value then
sizeof(struct virtio_net_hdr), and if po->has_vnet_hdr
is set, an out-of-bounds write will occur when
calling virtio_net_hdr_from_skb.
The bug is fixed by converting netoff to unsigned int
and checking if it exceeds USHRT_MAX.
