Add a global resource manager to manage tagged pointers within
bootmem allocated memory. This is used by various functional

We want to add the Cavium OCTEON-III network driver. But since
interacting with the input and output queues is done via special CPU
local memory, we also need to add support to the MIPS/Octeon
architecture code. Aren't SoCs nice in this way? These are the
prerequisite patches that are needed bef

The patch adds 'external' option to support collect metadata
gre6 tunnel. The 'external' keyword is already used to set the
device into collect metadata mode such as vxlan, geneve, ipip,
etc. This patch extends support for ipv6 gre and gretap.

CONFIG_BPF_SYSCALL is not set for this build.

Much better.

Only the retransmit timer currently refreshes tcp_mstamp
We should do the same for delayed acks and keepalives.
Even if RFC 7323 does not request it, this is consistent to what linux
did in the past, when TS values were based on jiffies.

Our chosen ic_dev may be anywhere in our list of ic_devs, and we may
free it before attempting to close others. When we compare d->dev and
ic_dev->dev, we're potentially dereferencing memory returned to the

Hi,
I am planning to update selftests/net/config.
Before submitting a patch upstream i would like to get your opinion,
Test cases added to selftests/net
- do "reuseport_bpf_numa.c" need CONFIG_NUMA=y ?
- do "reuseport_bpf_cpu.c" need CONFIG_USE_PERCPU_NUMA_NODE_ID=y ?
