batman-adv uses a self-written reference implementation which is just based
on atomic_t. This is less obvious when reading the code than kref and
therefore increases the change that the reference counting will be missed.Signed-off-by: Sven Eckelmann

Factor out register bit twiddling in the Renesas Ethernet driversHere's a set of 2 patches against DaveM's 'net-next.git' repo. We factor out

The driver has often repeated pattern of reading a register, AND'ing and/or
OR'ing some bits and writing the value back. Factor the pattern out into
sh_eth_modify() -- this saves 84 bytes of code with ARM gcc 4.7.3.While at it, update Cogent Embedded's copyright.

====================
packet: tpacket gso and csum offloadExtend PACKET_VNET_HDR socket option support to packet sockets with
memory mapped rings.Patches 2 and 4 add support to tpacket_rcv and tpacket_snd.
Patch 1 prepares for this by moving the relevant virtio_net_hdr
logic out of packet_snd and packet_rcv into helper functions.GSO transmission requires all headers in the skb linear section.
Patch 3 moves parsing of tx_ring slot headers before skb allocation
to enable allocation with sufficient linear size.Changes
v1->v2:
- fix bounds checks:
- subtract sizeof(vnet_hdr) before comparing tp_len to size_max
- compare tp_len to size_max also with GSO, just do not truncate to MTU

Support socket option PACKET_VNET_HDR together with PACKET_TX_RING.
When enabled, a struct virtio_net_hdr is expected to precede the data
in the ring. The vnet option must be set before the ring is created.The implementation reuses the existing skb_copy_bits code that is used
when dev->hard_header_len is non-zero. Move this ll_header check to
before the skb alloc and combine it with a test for vnet_hdr->hdr_len.
Allocate and copy the max of the two.Verified with test program at

GSO packet headers must be stored in the linear skb segment.
Move tpacket header parsing before sock_alloc_send_skb. The GSO
follow-on patch will later increase the skb linear argument to
sock_alloc_send_skb if needed for large packets.The header parsing code does not require an allocated skb, so is
safe to move. Later pass to tpacket_fill_skb the computed data
start and length.Signed-off-by: Willem de Bruijn

packet_snd and packet_rcv support virtio net headers for GSO.
Move this logic into helper functions to be able to reuse it in
tpacket_snd and tpacket_rcv.This is a straighforward code move with one exception. Instead of
creating and passing a separate gso_type variable, reuse
vnet_hdr.gso_type after conversion from virtio to kernel gso type.Signed-off-by: Willem de Bruijn

Currently the bonding allows to set ad_actor_system and prio while the
bond device is down, but these are actually applied only if there aren't
any slaves yet (applied to bond device when first slave shows up, and to
slaves at 3ad bind time). After this patch changes are applied immediately
and the new values can be used/seen after the bond's upped so it's not
necessary anymore to release all and enslave again to see the changes.CC: Jay Vosburgh

Nikolay Borisov says:
====================
Namespaceify more of the tcp sysctl knobsThis patch series continues making more of the tcp-related
sysctl knobs be per net-namespace. Most of these apply per
socket and have global defaults so should be safe and I
don't expect any breakages.Having those per net-namespace is useful when multiple
containers are hosted and it is required to tune the
tcp settings for each independently of the host node.I've split the patches to be per-sysctl but after
the review if the outcome is positive I'm happy
to either send it in one big blob or just.

virtio_net: add ethtool get/set settings supportPatch 1 adds ethtool speed/duplex validation functions which check if the
value is defined. Patch 2 adds support for ethtool (get|set)_settings and
uses the validation functions to check the user-supplied values.v2: split in 2 patches to allow everyone to make use of the validation
functions and allow virtio_net devices to be half duplex
v3: added a check to return error if the user tries to change anything else
besides duplex/speed as per Michael's comment
v4: Set port type to PORT_OTHER
v5: clear diff1.port (ignore port) when checking for changes since we set
it now and ethtool uses it in the set requestSorry about the pointless iterations, should've all covered now.

This patch allows the user to set and retrieve speed and duplex of the
virtio_net device via ethtool. Having this functionality is very helpful
for simulating different environments and also enables the virtio_net
device to participate in operations where proper speed and duplex are
required (e.g. currently bonding lacp mode requires full duplex). Custom
speed and duplex are not allowed, the user-supplied settings are validated
before applying.Example:
$ ethtool eth1
Settings for eth1:
...
Speed: Unknown!
Duplex: Unknown! (255)
$ ethtool -s eth1 speed 1000 duplex full
$ ethtool eth1
Settings for eth1:
...
Speed: 1000Mb/s
Duplex: FullBased on a patch by Roopa Prabhu.

tcp: congestion control refactoringThis patch set refactors the sequence of congestion control,
loss recovery, and transmission logic in TCP ack processing.The design goal is to decouple and sequence them in the following order:
0. ACK accounting: free or tag sent packets [unchanged]
1. loss recovery: identify lost/ecn packets and update congestion state
2. congestion control: up/down cwnd and pacing rate based on (1)
3. transmission: send new or retransmit old based on (1) and (2)
This refactoring makes the cwnd changes more clear because it's done
in one place. The packet accounting is also more robust especially
for connections that do not support SACK. Patch 1-4 and 6 are
refactoring and patch 5 improves TCP performance under reordering.
