The recv cache is to allocate 125MiB memory to reserve for NIC.

A recv cache is added. The size of recv cache is 1000Mb / skb_length.
When the system memory is not enough, this recv cache can make nic work

is down, this recv cache will be destroyed and delayed workqueue is
canceled.
This recv cache is to make NIC work steadily when the system memory is

Hi James
What exactly do you mean by a 'local' interface? The IP address on the
interface has scope local?

I have a question - maybe someone can point me in the right direction?
When there exist two or more "local" interfaces on the "host" system, where
sysctl "net.ipv4.conf..forwarding=1" has been set, and where each
interface has an IP address on a different subnet, then, when a frame arrives

Both ip_neigh_gw4() and ip_neigh_gw6() can return either a valid pointer
or an error pointer, but the code currently checks that the pointer is
not NULL.
Fix this by checking that the pointer is not an error pointer, as this
can result in a NULL pointer dereference [1]. Specif

Quoting Arnd,
We have to do a sync_single_for_device /somewhere/ before the
buffer is given to the device. On a non-cache-coherent machine with
a write-back cache, there may be dirty cache lines that get written back
after the device DMA's data into it (e.g. from a previous memset

Currently, TC offers the ability to match on the MPLS fields of a packet
through the use of the flow_dissector_key_mpls struct. However, as yet, TC
actions do not allow the modification or manipulation of such fields.
Add a new module that registers TC action ops to allow manipulation of
MPLS. Thi
This patchset introduces a new TC action module that allows the
manipulation of the MPLS headers of packets. The code impliments
functionality including push, pop, and modify.
Also included are tests for the new funtionality. Note that these will
require iproute2 changes to be submitted soon.
