tcp: increase throughput when reordering is high
The stack currently detects reordering and avoid spurious
retransmission very well. However the throughput is sub-optimal under
high reordering because cwnd is increased only if the data is deliverd
in order. I.e., FLAG_DATA_ACKED check in tcp_ack(). The more packet
are reordered the worse the throughput is.
Therefore when reordering is proven high, cwnd should advance whenever
the data is delivered regardless of its ordering. If reordering is low,
conservatively advance cwnd only on ordered deliveries in Open state,
and retain cwnd in Disordered state (RFC5681).
Using netperf on a qdisc setup of 20Mbps BW and random RTT from 45ms
to 55ms (for reordering effect). This change increases TCP throughput
by 20 - 25% to near bottleneck BW.
A special case is the stretched ACK with new SACK and/or ECE mark.
For example, a receiver may receive an out of order or ECN packet with
unacked data buffered because of LRO or delayed ACK. The principle on
such an ACK is to advance cwnd on the cummulative acked part first,
then reduce cwnd in tcp_fastretrans_alert().

Intel Wired LAN Driver Updates

Akeem provides 3 igb patches, the first resets the link when EEE is enabled
or disabled if the link is up. His second patch changes a register read
which normally stores of the read value to "just-read" so that hardware
can accurately latch the register read. Lastly, he adds rcu_lock to avoid
a possible race condition with igb_update_stats function.
Mitch provides a fix for SR-IOV, where MSI-X interrupts are required, so
make sure that MSI-X is enabled before allowing the user to turn on SR-IOV.
Alex's igb patch make it so that we limit the lower bound for max_frame_size
to the size of a standard Ethernet frame. This allows for feature parity
with other Intel based drivers such as ixgbe.
Carolyn adds a SKU for a flashless i210 device and a fix for get_fw_version()
so that it works for all parts for igb. In addition, she has 2 igb patches
to refactor NVM code to accommodate devices with no flash. Lastly, she
adds code to check for the failure of pci_disable_link_state() to attempt
to work around a problem found with some systems.
Laura provides the remaining 2 igb patches. One removing the hard-coded
value for the size of the RETA indirection table, and creates a macro instead
for the RETA indirection table. The second adds the ethtool callbacks
necessary to change the RETA indirection table from userspace.
Bruce fixes a whitespace issue in a recent commit and resolves a jiffies
comparison warning by using time_after().
Li provides a fix for e1000e to avoid a kernel crash on shutdown by adding
one more check in e1000e_shutdown(). This is due to e1000e_shutdown()
trying to clear correctable errors on the upstream P2P bridge, when under

In order to achieve this, we add the indirection table field (rss_indir_tbl)

The indirection table must be initialized with default values in the
following cases:
* at module init time
* when the number of RX queues changes.
For this reason we add a new field (rss_indir_tbl_init) in igb_adapter

tun: Some bits required for tun's checkpoint-restore (v2)
After taking a closer look on tun checkpoint-restore I've found several

The proposed API changes are all about extending the existing ioctl-based

tun: Allow to skip filter on attach
There's a small problem with sk-filters on tun devices. Consider
an application doing this sequence of steps:
fd = open("/dev/net/tun");
ioctl(fd, TUNSETIFF, { .ifr_name = "tun0" });
ioctl(fd, TUNATTACHFILTER, &my_filter);
ioctl(fd, TUNSETPERSIST, 1);
close(fd);
At that point the tun0 will remain in the system and will keep in
mind that there should be a socket filter at address '&my_filter'.
If after that we do
fd = open("/dev/net/tun");
ioctl(fd, TUNSETIFF, { .ifr_name = "tun0" });
we most likely receive the -EFAULT error, since tun_attach() would
try to connect the filter back. But (!) if we provide a filter at
address &my_filter, then tun0 will be created and the "new" filter
would be attached, but application may not know about that.
This may create certain problems to anyone using tun-s, but it's
critical problem for c/r -- if we meet a persistent tun device
with a filter in mind, we will not be able to attach to it to dump
its state (flags, owner, address, vnethdr size, etc.).
The proposal is to allow to attach to tun device (with TUNSETIFF)
w/o attaching the filter to the tun-file's socket. After this
attach app may e.g clean the device by dropping the filter, it
doesn't want to have one, or (in case of c/r) get information
about the device with tun ioctls.

Long time ago such ability was implemented for rtnl_ops-based

tuntap devices is ioctl-based and is evolving with adding new ones

Following that trend, here's how a new ioctl that sets the ifindex
for device, that _will_ be created by TUNSETIFF ioctl looks like.
So those who want a tuntap device with the ifindex N, should open
the tun device, call ioctl(fd, TUNSETIFINDEX, &N), then call TUNSETIFF.
If the index N is busy, then the register_netdev will find this out
and the ioctl would be failed with -EBUSY.

CPSW driver no longer supports platform register as all the SoCs which has CPSW
are supporting DT only booting, so moving cpsw.h header file from platform
include to drivers/net/ethernet/ti

ip6_tunnel: ensure to always have a link local address
When an Xin6 tunnel is set up, we check other netdevices to inherit the link-
local address. If none is available, the interface will not have any link-local
address. RFC4862 expects that each interface has a link local address.
Now than this kind of tunnels supports x-netns, it's easy to fall in this case
(by creating the tunnel in a netns where ethernet interfaces stand and then
moving it to a other netns where no ethernet interface is available).
RFC4291, Appendix A suggests two methods: the first is the one currently
implemented, the second is to generate a unique identifier, so that we can
always generate the link-local address. Let's use eth_random_addr() to generate
this interface indentifier.
I remove completly the previous method, hence for the whole life of the
interface, the link-local address remains the same (previously, it depends on
which ethernet interfaces were up when the tunnel interface was set up).

This reverts commit

These changes are buggy and make unintended semantic changes

bcm63xx_enet: replace devm_request_and_ioremap by devm_ioremap_resource
Use devm_ioremap_resource instead of devm_request_and_ioremap.
This was done using the semantic patch
scripts/coccinelle/api/devm_ioremap_resource.cocci
The relevant call to platform_get_resource was manually moved down to the
call to devm_ioremap_resource.
