So far, neighbour's secondary interface OGMs can involuntarily
piggyback on primary interface OGMs that arrived on the same secondary
interface before. Secondary interface OGMs should NEVER leave their
direct neighbour broadcast domain! This patch ensures that secondary
interface OGMs can only be aggregated to other secondary interface OGMs.

batman-adv aggregates routing packets to reduce the number of packets in
the air. Every outgoing packet is compared with other packets in the
buffer to determine whether it can be aggregated or not. Packets sent
at a lower interval can be held back longer to maximize the aggregation.
Due to insufficient checking batman-adv held back all packets for a
certain time depending on its own lowest interval rate which slowed
down all other nodes.

"tcpdump" and "batctl td" will receive packets with a wrong sequence
number on systems with a different endianess than network byte order.
This happens due to the reordering of bytes in the function which
handles aggregated bat packets. The function which receives the bat
packets must ensure that these buffers aren't shared with anything else
before that function tries to write into it. Otherwise it has to copy
the buffers so it is save again to change them.

If we haven't set the module to MODULE_ACTIVE state before (in general,
no interface has yet been added to batman-adv) then the hna table is not
initialised yet. If the kernel changes the mac address of the bat0
interface at this moment then an hna_local_add() called by interface_set_mac_addr()
then resulted in a null pointer derefernce. With this patch we are now
explicitly checking before if the state is MODULE_ACTIVE right now so
that we can assume having an initialised hna table.

Jumbo frames are not supported, and if they are seen it is likely
a bogus frame so just silently discard them instead of warning on
them all time. Also, instead of dropping them immediately though
move the check *after* we check for all sort of frame errors. This
should enable us to discard these frames if the hardware picks
other bogus items first. Lets see if we still get those jumbo
counters increasing still with this.
Jumbo frames would happen if we tell hardware we can support
a small 802.11 chunks of DMA'd frame, hardware would split RX'd
frames into parts and we'd have to reconstruct them in software.
This is done with USB due to the bulk size but with ath5k we
already provide a good limit to hardware and this should not be
happening.
This is reported quite often and if it fills the logs then this
needs to be addressed and to avoid spurious reports.

I noticed that when I inject a fatal error to an endpoint via
aer-inject, aer_root_reset() is called as reset_link for a
downstream port at upstream of the endpoint:
pcieport 0000:00:06.0: AER: Uncorrected (Fatal) error received: id=5401
:
pcieport 0000:52:02.0: Root Port link has been reset
It externally appears to be working, but internally issues some
accesses to PCI_ERR_ROOT_COMMAND/STATUS registers that is for
root port so not available on downstream port.
This patch introduces default_downstream_reset_link that is
a version of aer_root_reset() with no accesses to root port's
register. It is used for downstream ports that has no reset_link
function its specific.
This patch also updates related description in pcieaer-howto.txt.

The pcie->port of port service device points the port associated
the service with. The find_aer_service iterates over children of
given port udev.
So it is clear that the pcie->port of port service of given port
udev must always point the udev.
Therefore we can know the type of udev without checking its children.

This cleanup solves some minor naming issues by removing unuseful
function aer_delete_rootport() and by renaming disable_root_aer()
to aer_disable_rootport().
- Inconsistent location of alloc & free:
The struct rpc is allocated in aer_alloc_rpc() at aerdrv.c
while it is implicitly freed in aer_delete_rootport() at
aerdrv_core.c.
- Inconsistent function name:
It makes a bit confusion that aer_delete_rootport() is seemed
to be paired with aer_enable_rootport(), i.e. there is neither
"add" against "delete" nor "disable" against "enable".

SuperIO devices share regions and use lock/unlock operations to chip
select. We therefore need to be able to request a resource and wait for
it to be freed by whichever other SuperIO device currently hogs it.
Right now you have to poll which is horrible.
Add a MUXED field to IO port resources. If the MUXED field is set on the
resource and on the request (via request_muxed_region) then we block
until the previous owner of the muxed resource releases their region.
This allows us to implement proper resource sharing and locking for
superio chips using code of the form
enable_my_superio_dev() {
request_muxed_region(0x44, 0x02, "superio:watchdog");
outb() ..sequence to enable chip
}
disable_my_superio_dev() {
outb() .. sequence of disable chip
release_region(0x44, 0x02);
}

sapphire:/sys/bus/pci/slots # ls -l 3
