Adds support for RTNH_F_DEAD and RTNH_F_LINKDOWN flags on mpls
routes due to link events. Also adds code to ignore dead
routes during route selection.
Unlike ip routes, mpls routes are not deleted when the route goes
dead. This is current mpls behaviour and this patch does not

Add a new msg flag called MSG_BATCH. This flag is used in sendmsg to
indicate that more messages will follow (i.e. a batch of messages is

This patch adds the support of "TSO (TCP Segment Offload)" feature
provided by the Hip06 ethernet hardware to the HNS ethernet
driver.
Enabling this feature would help offload the TCP Segmentation
process to the Hip06 ethernet hardware. This eventually would help
in saving precious cpu cycles.

This patch adds the support of "RSS (Receive Side Scaling)" feature
provided by the Hip06 ethernet hardware to the HNS ethernet
driver.
This feature helps in distributing the different flows (mapped as
hash by hardware using Toeplitz Hash) to different Queues asssociated
with the processor cores.
This patch adds the initializzation code to disable the hardware
vlan support for VLAN Tag stripping by default for now.
Proper support of "hardware VLAN assitance" feature would
soon come in the next coming patches.

Hi all.
Today some BRASes on 4.1.12 kernel were crashed.
Here's crash traces: http://pastebin.com/p68hNS8R
http://pastebin.com/36ieRAM2 http://pastebin.com/3BRTVEB6
On 3.2 kernel same hardware works OK, troubles were noticed after kernel
upgrade.
What additional info is needed?

When destroying an mrt table the static mfc entries and the static
devices are kept, which leads to devices that can never be destroyed
(because of refcnt taken) and leaked memory, for example:

Hi,
While testing various ipmr scenarios I found that static mfc entries and
static devices get leaked on netns/table destruction because
mroute_clean_tables doesn't delete them. It is fine to leave the static
entries when cleaning up the mrtsock, but when destroying the
