The typical convention when having both a child and a parent channel
variable is to call the former 'chan' and the latter 'pchan'. When
there's only one variable it's called chan. Rename the 'pchan'
variables in the 6lowpan code to follow this convention.

The L2CAP core code makes sure of setting the channel state to

The L2CAP core code already sets the local MPS to a sane value. The

The omtu value is determined by the remote peer so there's no point in
trying to hard-code it to any value. The IPSP specification otoh gives
a more reasonable value for the imtu, i.e. 1280.

When the controller requires the HCI Reset command to be send when
closing the transport, the HCI_AUTO_OFF needs to be accounted for. The
current code tries to actually do that, but the flag gets cleared to
early. So store its value and use it that stored value instead of
checking for a flag that is always cleared.

The Bluetooth public device address might change during controller setup
and it makes it a lot simpler for monitoring tools if they just get told

Previously, the CT_ATTR_FLAGS attribute, when nested under the
OVS_ACTION_ATTR_CT, encoded a 32-bit bitmask of flags that modify the
semantics of the ct action. It's more extensible to just represent each
flag as a nested attribute, and this requires no additional error
checking to reject flags that aren't currently supported.

The ct_state field was initially added as an 8-bit field, however six of
the bits are already being used and use cases are already starting to
appear that may push the limits of this field. This patch extends the
field to 32 bits while retaining the internal representation of 8 bits.
This should cover forward compatibility of the ABI for the foreseeable
future.
This patch also reorders the OVS_CS_F_* bits to be sequential.

Previously, if userspace specified ct_state bits in the flow key which
are currently undefined (and therefore unsupported), then they would be
ignored. This could cause unexpected behaviour in future if userspace is
extended to support additional bits but attempts to communicate with the
current version of the kernel. This patch rectifies the situation by
rejecting such ct_state bits.

8K message sizes are pretty important usecase for RDS current
workloads so we make provison to have 8K mrs available from the pool.
Based on number of SG's in the RDS message, we pick a pool to use.
Also to make sure that we don't under utlise mrs when say 8k messages
are dominating which could lead to 8k pull being exhausted, we fall-back
to 1m pool till 8k pool recovers for use.
This helps to at least push ~55 kB/s bidirectional data which
