Increasing the buffer size used in rtnl_dump_filter_l 3x empirically resolves

The root-cause is due to the buffer size calculation of dump request in the

Hi,
Running on Xen testing a 4.2-rc4 kernel it got the crash below.
Could this be related to the changes in
3bb475a3446facd0425d3f2fe7e85bf03c5c6c05 ?
It crashes dom0 when i put some strain onto the network + bridge.

This is similar to command options corresponding to other NTF_* flags
already exposed to the user space (examples self/master).
Also updates bridge man page (The man page patch also includes
a fix to the 'self' entry and documents 'master' for fdb entries)

Virtual interfaces don't necessarily need a qdisc attached to them. This
is signalled by setting dev->tx_queue_len to zero upon initialisation. The
problems begin when a user still adds a qdisc, as then the special value
is used as a regular one causing massive packet drops as soon as the
device se
From: Jesper Dangaard Brouer
The veth driver is a virtual device, and should not have assigned
the default qdisc. Verified (ndo_start_xmit) veth_xmit can only
return NETDEV_TX_OK, thus this should be safe to bypass qdisc.
Not assigning a qdisc is subtly done by setting tx_queue_len to zero.

This series is inspired by a patch sent[1] in from Jesper Brouer and the
discussion it started. Basically it tries to provide a solution which is
backwards compatible while still enabling the veth performance
improvement by default.

The intent of this function was to produce a consistent hash for both
directions of a flow. However, since we added more inputs to the flow
hashing (IPv6 flow labels for instance) in a lot of cases we won't get
the same hash computed for each direction anyway. Also, there is no
defined correlation

v2:
- Rebase to DaveM's net tree, context-only change
- Add Mitch's Acks
There's no functional change from v1, so the choice of v1 or v2 is
just a matter of which maintainer wants to take these.
