Add a small helper skb_postpush_rcsum() and fix up redirect locations
that need CHECKSUM_COMPLETE fixups on ingress. dev_forward_skb() expects
a proper csum that covers also Ethernet header, f.e. since 2c26d34bbcc0
("net/core: Handle csum for CHECKSUM_COMPLETE VXLAN forwarding"), we
also do skb_postpull_rcsum() after pulling Ethernet header off via
eth_type_trans().

When using eBPF in a netns setup f.e. with vxlan in collect metadata mode,
I can trigger the following csum issue with an IPv6 setup:

What happens is that on ingress, we push Ethernet header back in, either
from cls_bpf or right before skb_do_redirect(), but without updating csum.
The "hw csum failure" can be fixed by using the new skb_postpush_rcsum()
helper for the dev_forward_skb() case to correct the csum diff again.

Thanks to Hannes Frederic Sowa for the csum_partial() idea!

Nikolay Borisov says:

====================
Namespaceify tcp keepalive machinery

The following patch series enables the tcp keepalive mechanism
to be configured per net namespace. This is especially useful
if you have multiple containers hosted on one node and one of
them is under DoS-  in such situations one thing which could
be done is to configure the tcp keepalive settings such that
connections for that particular container are being reset
faster.

Another scenario where not being able to control those knob
comes per container is problematic is occurs the value of
net.netfilter.nf_conntrack_tcp_timeout_established is set
below the keepalive interval, in such situations the server won't
send an RST packet resulting in applications not trying to
reconnect and stale connection waiting. Changing the global
keepalive value is a possible solution but it might interfere
with other containers.

The three patches gradually convert each of the affected knobs
to be per netns. I thought it would be easier for review than
put everything in one patch. If people deem it more appropriate
to squash everything in one patch (maybe after review) I'd
be more than happy to do it.

The patches have been compile-tested on 4.4 and functionally
tested on 3.12 and they work as expected.

These are based off 4.4-rc8

10GbE Intel Wired LAN Driver Updates 2016-01-08

Vasu provides three fixes for ixgbe, first assigns a minimum credit to
a traffic class to resolve a Tx hang for CEE mode configuration.  Second
fix changes the driver to use netdev->fcoe_ddp_xid instead of our local
IXGBE_FCOE_DDP_MAX, since it is correctly set for our different devices
and avoids a DDP skip error on X550.  Lastly fix the PFC configuration
to include X550 devices.

Emil provides a fix for reporting the speed in ethtool by using the
stored value in out adapter structure.  This is due to external drivers
may end up with unknown speed when calling ethtool_get_settings().

Mark fixes the handling of any outer UDP checksum, by passing the
skb up with CHECKSUM_NONE when an outer UDP checksum is set.  This
will cause the stack to check the checksum, also do not increment an
error counter because we do not really know if there is an actual error.
Ixgbe ATR was not handling IPv6 extended headers, so ATR is not being
performed on such packets.  Fix this by skipping extended headers
when they are present.

Usha fixes an issue with X550 and getting FDMI HBA attributes when
FCoE support is enabled.

Neerav fixes an issue for X550 when FCoE and SR-IOV are enabled, which
the hardware generates MDD events.  Resolve this by setting the expected
values in the transmit context descriptors for FCoE/FIP frames and
adding a flush after writing the RDLEN register.

in the Open Firmware on systems that support it and use IDPROM on SPARC
