The driver was examining the outer protocol layer to set the inner protocol
layer checksum offload.  In the case of TCP over IPV6 over an IPv4 based
VXLAN the inner checksum offloads would be set to look for IPv4/UDP instead
of IPv6/TCP.  This code fixes that so that the driver will look at the
proper layer for encapsulation offload settings.

When the driver was polling with interrupts disabled the hardware
will occasionally not write back descriptors.  This patch causes
the driver to detect this situation and force an interrupt to
fire which will flush the stuck descriptor.  Does not conflict
with napi because if we are already polling the napi_schedule is
ignored.  Additionally the extra interrupts are rate limited, so
don't cause a burden to the CPU.

This patch fixes a potential memory leak which can occur once an
originator times out. On timeout the according global translation table
entry might not get purged correctly. Furthermore, the non purged TT
entry will cause its orig-node to leak, too. Which additionally can lead
to the new multicast optimization feature not kicking in because of a
therefore bogus counter.

In detail: The batadv_tt_global_entry->orig_list holds the reference to
the orig-node. Usually this reference is released after
BATADV_PURGE_TIMEOUT through: _batadv_purge_orig()->
batadv_purge_orig_node()->batadv_update_route()->_batadv_update_route()->
batadv_tt_global_del_orig() which purges this global tt entry and
releases the reference to the orig-node.

However, if between two batadv_purge_orig_node() calls the orig-node
timeout grew to 2*BATADV_PURGE_TIMEOUT then this call path isn't
reached. Instead the according orig-node is removed from the
originator hash in _batadv_purge_orig(), the batadv_update_route()
part is skipped and won't be reached anymore.

Fixing the issue by moving batadv_tt_global_del_orig() out of the rcu
callback.

When purging an orig_node we should only decrease counter tracking the
number of nodes without multicast optimizations support if it was
increased through this orig_node before.

A not yet quite initialized orig_node (meaning it did not have its turn
in the mcast-tvlv handler so far) which gets purged would not adhere to
this and will lead to a counter imbalance.

Fixing this by adding a check whether the orig_node is mcast-initalized
before decreasing the counter in the mcast-orig_node-purging routine.

A miscounting of nodes having multicast optimizations enabled can lead
to multicast packet loss in the following scenario:

If the first OGM a node receives from another one has no multicast
optimizations support (no multicast tvlv) then we are missing to
increase the counter. This potentially leads to the wrong assumption
that we could safely use multicast optimizations.

Fixings this by increasing the counter if the initial OGM has the
multicast TVLV unset, too.

Currently it can happen that the reception of an OGM from a new
originator is not being accepted. More precisely it can happen that
an originator struct gets allocated and initialized
(batadv_orig_node_new()), even the TQ gets calculated and set correctly
(batadv_iv_ogm_calc_tq()) but still the periodic orig_node purging
thread will decide to delete it if it has a chance to jump between
these two function calls.

This is because batadv_orig_node_new() initializes the last_seen value
to zero and its caller (batadv_iv_ogm_orig_get()) makes it visible to
other threads by adding it to the hash table already.
batadv_iv_ogm_calc_tq() will set the last_seen variable to the correct,
current time a few lines later but if the purging thread jumps in between
that it will think that the orig_node timed out and will wrongly
schedule it for deletion already.

If the purging interval is the same as the originator interval (which is
the default: 1 second), then this game can continue for several rounds
until the random OGM jitter added enough difference between these
two (in tests, two to about four rounds seemed common).

Fixing this by initializing the last_seen variable of an orig_node
to the current time before adding it to the hash table.

This reverts commit ca34e3b5.

It turns out that the p54 and cw2100 drivers assume that there's
tailroom even when they don't say they really need it. However,
there's currently no way for them to explicitly say they do need
it, so for now revert this.

The CPSW IP implements pulse-signaled interrupts. Due to
that we must write a correct, pre-defined value to the
CPDMA_MACEOIVECTOR register so the controller generates
a pulse on the correct IRQ line to signal the End Of
Interrupt.

The way the driver is written today, all four IRQ lines
are requested using the same IRQ handler and, because of
that, we could fall into situations where a TX IRQ fires
but we tell the controller that we ended an RX IRQ (or
vice-versa). This situation triggers an IRQ storm on the
reserved IRQ 127 of INTC which will in turn call ack_bad_irq()
which will, then, print a ton of:

	unexpected IRQ trap at vector 00

In order to fix the problem, we are moving all calls to
cpdma_ctlr_eoi() inside the IRQ handler and making sure
we *always* write the correct value to the CPDMA_MACEOIVECTOR
register. Note that the algorithm assumes that IRQ numbers and
value-to-be-written-to-EOI are proportional, meaning that a
write of value 0 would trigger an EOI pulse for the RX_THRESHOLD
Interrupt and that's the IRQ number sitting in the 0-th index
of our irqs_table array.

This, however, is safe at least for current implementations of
CPSW so we will refrain from making the check smarter (and, as
a side-effect, slower) until we actually have a platform where
IRQ lines are swapped.

This patch has been tested for several days with AM335x- and
AM437x-based platforms. AM57x was left out because there are
still pending patches to enable ethernet in mainline for that
platform. A read of the TRM confirms the statement on previous
paragraph.

Some buggy firmwares export an incorrect MAC address (00:a0:c6:00:00:00). This

This patch tries to fix, or at least improve, the situation by setting the MAC
address of devices with this firmware bug to a random address. I tested the

Thomas Jarosch reported IPsec TCP stalls when a PMTU event occurs.

In fact the problem was completely unrelated to IPsec.  The bug is
also reproducible if you just disable TSO/GSO.

The problem is that when the MSS goes down, existing queued packet
on the TX queue that have not been transmitted yet all look like
TSO packets and get treated as such.

This then triggers a bug where tcp_mss_split_point tells us to
generate a zero-sized packet on the TX queue.  Once that happens
we're screwed because the zero-sized packet can never be removed
by ACKs.
