In test_halt() we set an endpoint halt condition and return on halt verification
failure, then the enpoint will remain halted and all further tests related
to that enpoint will fail. This is because we don't tackle endpoint halt error condition

The pointer arithmetic in this function was really bizarre, where in
fact all we really wanted was a simple pointer array walk. Use the
much more idiomatic construction for that (*ptr++).
Factor an invariant use of __pa() out of the relocation loop. At
least on 64 bits it seems gcc isn't capable of doing that
automatically.
Change the scope of a couple of variables to make it extra obvious
that they are extremely local temp variables.

While testing my changes for TSO support in SIT devices,
I was using sit0 tunnel which appears to include nopmtudisc flag.
But using :
ip tun add sittun mode sit remote $REMOTE_IPV4 local $LOCAL_IPV4 \
dev $IFACE
We get a tunnel which rejects too long packets because of the mtu check
which is not yet GSO aware.
erd:~# ip tunnel
sittun: ipv6/ip remote 10.246.17.84 local 10.246.17.83 ttl inherit 6rd-prefix 2002::/16
sit0: ipv6/ip remote any local any ttl 64 nopmtudisc 6rd-prefix 2002::/16
This patch is based on an excellent report from
Michal Shmidt.
In the future, we probably want to extend the MTU check to do the
right thing for GSO packets...

Sockets marked with IPV6_PMTUDISC_PROBE (or later IPV6_PMTUDISC_INTERFACE)
don't respect this setting when the outgoing interface supports UFO.
We had the same problem in IPv4, which was fixed in commit
daba287b29 ("ipv4: fix DO and PROBE pmtu
mode regarding local fragmentation with UFO/CORK").
Also IPV6_DONTFRAG mode did not care about already corked data, thus
it may generate a fragmented frame even if this socket option was
specified. It also did not care about the length of the ipv6 header and
possible options.
In the error path allow the user to receive the pmtu notifications via
both, rxpmtu method or error queue. The user may opted in for both,
so deliver the notification to both error handlers (the handlers check
if the error needs to be enqueued).
Also report back consistent pmtu values when sending on an already
cork-appended socket.

Certain dm962x revisions contain an bug, where if a USB bulk transfer retry
(E.G. if bulk crc mismatch) happens right after a transfer with odd or
maxpacket length, the internal tx hardware fifo gets out of sync causing
the interface to stop working.
Work around it by adding up to 3 bytes of padding to ensure this situation
cannot trigger.
This workaround also means we never pass multiple-of-maxpacket size skb's
to usbnet, so the length adjustment to handle usbnet's padding of those can
be removed.

ipgre_header_parse() needs to parse the tunnel's ip header and it
uses mac_header to locate the iphdr. This got broken when gre tunneling
was refactored as mac_header is no longer updated to point to iphdr.
Introduce skb_pop_mac_header() helper to do the mac_header assignment
and use it in ipgre_rcv() to fix msg_name parsing.

IPV6_PMTU_INTERFACE is the same as IPV6_PMTU_PROBE for ipv6. Add it
nontheless for symmetry with IPv4 sockets. Also drop incoming MTU
information if this mode is enabled.

bitfield. There are no changes to the layout of the struct at all.

that the X.509 cert container object file would be rebuilt on the
second rebuild in a build directory and the kernel would get
