In 34666d4 ("netfilter: bridge: move br_netfilter out of the core"),
the bridge netfilter code has been modularized.Use IS_ENABLED instead of ifdef to cover the module case.

This patch introduces the NFT_REJECT_ICMPX_UNREACH type which provides
an abstraction to the ICMP and ICMPv6 codes that you can use from the
inet and bridge tables, they are:* NFT_REJECT_ICMPX_NO_ROUTE: no route to host - network unreachable
* NFT_REJECT_ICMPX_PORT_UNREACH: port unreachable
* NFT_REJECT_ICMPX_HOST_UNREACH: host unreachable
* NFT_REJECT_ICMPX_ADMIN_PROHIBITED: administratevely prohibitedYou can still use the specific codes when restricting the rule to match
the corresponding layer 3 protocol.I decided to not overload the existing NFT_REJECT_ICMP_UNREACH to have
different semantics depending on the table family and to allow the user
to specify ICMP family specific codes if they restrict it to the
corresponding family.Signed-off-by: Pablo Neira Ayuso

Proper CHECKSUM_COMPLETE support needs to adjust skb->csum
when we remove one header. Its done using skb_gro_postpull_rcsum()In the case of IPv4, we know that the adjustment is not really needed,
because the checksum over IPv4 header is 0. Lets add a comment to
ease code comprehension and avoid copy/paste errors.Signed-off-by: Eric Dumazet

sunvnet: add jumbo frames supportThis patch set updates the sunvnet driver to version 1.6 of the VIO protocol
to support per-port exchange of MTU information and allow non-standard MTU
sizes, including jumbo frames.Using large MTUs shows a nearly 5X throughput improvement Linux-Solaris
and > 10X throughput improvement Linux-Linux.Changes from v8:
-add a short timeout to free pending skbs if a new transmit doesn't
do it first per Dave Miller
Changes from v7:
-handle skb allocation failures in vnet_skb_shape()
per Dave Miller
Changes from v6:
-made kernel transmit path zero-copy to remove memory n^2 scaling issue
raised by Raghuram Kothakota
Changes from v5:
- fixed comment per Sowmini Varadhan
Changes from v4:
- changed VNET_MAXPACKET per David Laight
- added cookies to support non-contiguous buffers of max size
Changes from v3:
- added version functions per Dave Miller
- moved rmtu to vnet_port per Dave Miller

This patch sends ICMP and ICMPv6 messages for Path MTU Discovery when a remote
port MTU is smaller than the device MTU. This allows mixing newer VIO protocol
devices that support MTU negotiation with older devices that do not on the
same vswitch. It also allows Linux-Linux LDOMs to use 64K-1 data packets even
though Solaris vswitch is limited to

This patch removes pre-allocated transmit buffers and instead directly maps
pending packets on demand. This saves O(n^2) maximum-sized transmit buffers,
for n hosts on a vswitch, as well as a copy to those buffers.Single-stream TCP throughput linux-solaris dropped ~5% for 1500-byte MTU,
but linux-linux at 1500-bytes increased ~20%.Signed-off-by: David L Stevens

ARM: Berlin: Ethernet supportThis series introduce support for the Ethernet controller on Berlin SoCs,
using the existing pxa168 Ethernet driver. In order to do this, DT
support is added to the driver alongside some other modifications and
fixes.This has been tested on a Berlin BG2Q DMP board.
Changes since v5:
- fixed the build when building the driver as a moduleChanges since v4:
- removed the phy-addr property and added a phy subnode
- added COMPILE_TEST for the pxa168_eth driverChanges since v3:
- moved the addition of pxa168_eth_get_mac_address() to the patch
using it firstChanges since v2:
- reworked how the MAC address is configured
- made the clock anonymousChanges since v1:
- removed custom Berlin Ethernet driver
- used the pxa168 Ethernet driver instead
- made modifications to the pxa168 driver (DT support, fixes)

This patch rework the way the MAC address is retrieved. The MAC address
can now, in addition to being random, be set in the device tree or
retrieved from the Ethernet controller MAC address registers. The
probing function will try to get a MAC address in the following order:
- From the device tree.
- From the Ethernet controller MAC address registers.
- Generate a random one.This patch also adds a function to read the MAC address from the

mlx4_core driver updatesA series from Jack and Co of low-level fixes for the mlx4_core driver
====================Signed-off-by: David S. Miller

ConnectX2 HCAs have max_mtu=4k and max_vl=8 vls. However, if you specify
a 4K mtu, the max_vl supported for 4K is 4 vls. The driver at startup
attempts to set a 4K mtu using the max_vl value obtained from QUERY_PORT.Since the max_vl value is 8 vls (which is supported up to 2K mtu size),
the first attempt to set the mtl/vl port value will fail, generating
the following error message in the log:mlx4_core 0000:06:00.0: command 0xc failed: fw status = 0x40
The driver then tries again, using mtu=4k, vls=4, and this succeeds.
Since we do not want to have this error message always displayed at driver
start when there are ConnectX2 HCAs on the host, we deprecate the error
message for this specific command/input_modifier/opcode_modifier/fw-status
to be debug.Signed-off-by: Jack Morgenstein

In the new flow, we separate the pci initialization and teardown
from the initialization and teardown of the other resources.__mlx4_init_one handles the pci resources initialization. It then
calls mlx4_load_one to initialize the remainder of the resources.When removing a device, mlx4_remove_one is invoked. However, now
mlx4_remove_one calls mlx4_unload_one to free all the resources except the pci
resources. When mlx4_unload_one returns, mlx4_remove_one then frees the
pci resources.The above separation will allow us to implement 'reset flow' in the future.
It will also enable more EQs for VFs and is a pre-step to the modern API to
enable/disable SRIOV.Also added nvfs; an integer array of size MLX4_MAX_PORTS + 1; to the mlx4_dev
struct. This new field is used to avoid parsing the num_vfs module parameter
each time the mlx4_restart_one is called.Signed-off-by: Majd Dibbiny

When unloading the host driver while there are VFs active on VMs,
