On physical systems the ram isn't initialized on boot. So, coreboot uses
the cache as ram in this boot phase. When exiting cache as ram, coreboot
calls INVD for making the cache consistent.
In a virtual environment ram is always initialized and the cache is
always consistent. So, we can safely ignore this call.

A replacement QAT driver will be imported, but this replacement does not
support Atom C2xxx hardware. So, the existing driver will be kept
around to provide opencrypto offload support for those chipsets.

Currently there is no upper bound on the PMTU value that is accepted.
Update hostcache only if the new pmtu is smaller than the current entry

Currently we accept any pmtu between IPV6_MMTU(1280B) and the link mtu.
In some network topologies could allow a bad actor to perform a DOS attack.
Contrary to IPv4 in IPv6 oversized packets are dropped, and a ICMP
PACKET_TOO_BIG message is sent back to the sender.
After receiving an ICMPv6 packet with pmtu bigger than the
current one the victim will start sending frames that will be dropped
a router with reduced MTU.
Although it will eventually receive another message with correct pmtu,
an attacker can still just inject their spoofed packets frequently
enough to overwrite the correct value.
This issue is described in detail in RFC8201, section 6.
Fix this by checking the current pmtu, and accepting the new one only
if it's smaller.

The BSD style commands (with names not ending in "sum") ignored the -c
options and the passed digest value when invoked with -q.
The man page stated that -q causes only the calculated digest to be
printed, but did not consider the case of both the -q and -c being
used in combination.
Since there is no warning that -c will be ignored when the -q option
is used, users night (and did) expect that the exit code would reflect
the matching of the calculated digest and the argument passed with -c.
This update implements and documents this expected behavior.
