must all have the same bind settings.
Fanouts are identified (within a network namespace) by a 16-bit ID.

CCID-2's cwnd increases like TCP during slow-start, which has implications for
* the local Sequence Window value (should be > cwnd),
* the Ack Ratio value.
Hence an exponential growth, if it does not reflect the actual network
conditions, can quickly lead to instability.
This patch adds congestion-window validation (RFC2861) to CCID-2:
* cwnd is constrained if the sender is application limited;
* cwnd is reduced after a long idle period, as suggested in the '90 paper
by Van Jacobson, in RFC 2581 (sec. 4.1);
* cwnd is never reduced below the RFC 3390 initial window.
As marked in the comments, the code is actually almost a direct copy of the
TCP congestion-window-validation algorithms. By continuing this work, it may
in future be possible to use the TCP code (not possible at the moment).
The mechanism can be turned off using a module parameter. Sampling of the
currently-used window (moving-maximum) is however done constantly; this is
used to determine the expected window, which can be exploited to regulate
DCCP's Sequence Window value.
This patch also sets slow-start-after-idle (RFC 4341, 5.1), i.e. it behaves like
TCP when net.ipv4.tcp_slow_start_after_idle = 1.
dccp ccid-2: Use existing function to test for data packets
This replaces a switch statement with a test, using the equivalent
function dccp_data_packet(skb). It also doubles the range of the field
`rx_num_data_pkts' by changing the type from `int' to `u32', avoiding
signed/unsigned comparison with the u16 field `dccps_r_ack_ratio'.
dccp ccid-2: move rfc 3390 function into header file

parts throughout the CCID-2 code need to call it (CCID-2 still uses RFC 3390).

dccp: combine the functionality of enqeueing and cloning
Realising the following call pattern,
* first dccp_entail() is called to enqueue a new skb and
* then skb_clone() is called to transmit a clone of that skb,
this patch integrates both into the same function.
This patch rearranges the order of statements of the slow-path input processing
(i.e. any other state than OPEN), to resolve the following issues.
1. Dependencies: the order of statements now better matches RFC 4340, 8.5, i.e.
step 7 is before step 9 (previously 9 was before 7), and parsing options in
step 8 (which may consume resources) now comes after step 7.
2. Sequence number checks are omitted if in state LISTEN/REQUEST, due to the
note underneath the table in RFC 4340, 7.5.3.
As a result, CCID processing is now indeed confined to OPEN/PARTOPEN states,
i.e. congestion control is performed only on the flow of data packets. This
avoids pathological cases of doing congestion control on those messages
which set up and terminate the connection.
3. Packets are now passed on to Ack Vector / CCID processing only after
- step 7 (receive unexpected packets),
- step 9 (receive Reset),
- step 13 (receive CloseReq),
- step 14 (receive Close)
and only if the state is PARTOPEN. This simplifies CCID processing:
- in LISTEN/CLOSED the CCIDs are non-existent;
- in RESPOND/REQUEST the CCIDs have not yet been negotiated;
- in CLOSEREQ and active-CLOSING the node has already closed this socket;
- in passive-CLOSING the client is waiting for its Reset.
In the last case, RFC 4340, 8.3 leaves it open to ignore further incoming
data, which is the approach taken here.
It is a function of SuperH architecture. There is no good to use
the function on a driver generally. So, the driver uses
dma_map_single() instead of __flush_purge_region.

Note that links may still be modified or renamed while a dump is

be2net: create/destroy rx-queues on interface open/close
On some skews, the BE card sends pause frames (and not drop pkts) if there are
no more posted buffers available for packet reception. This behaviour has a
side effect: When an interface is disabled, buffers are no longer posted on the
corresponding RX rings. All broadcast and multicast traffic being received on
the port will quickly fill up the PMEM and cause pause push back. As the PMEM
is shared by both the ports, all traffic being received on the other (enabled)
port also gets stalled.
The fix is to destroy RX rings when the interface is disabled. If there is no
RX ring match in the RXF lookup, the packets are discarded and so don't hog the
PMEM.
