When the interface is down, head/tail of the descriptor
ring address is set to 0 in netsec_netdev_stop().
But netsec hardware still keeps the previous descriptor
ring address, so there is inconsistency between driver
and hardware after interface is up at a later time.
To add
Marvell's PPv2 controller has a Packet Header parser, which uses a
fixed-size TCAM array of filter entries.
The mvpp2 driver reserves some ranges among the 256 TCAM entries to
perform MAC and VID filtering. The rest of the TCAM ids are freely usable
for other features, such as IPv4 proto matching.

Move logic of fib_convert_metrics into ip_metrics_convert. This allows
the code that converts netlink attributes into metrics struct to be
re-used in a later patch by IPv6.
This is mostly a code move with the following changes to variable names:
- fi->fib_net becomes net
- fc_mx and fc_mx_len
The RTN_ type for IPv6 FIB entries is currently embedded in rt6i_flags
and dst.error. Since dst is going to be removed, it can no longer be
relied on for FIB dumps so save the route type as fib6_type.

When would user set this flag? Wouldn't that be when

SO_RCVLOWAT is properly handled in tcp_poll(), so that POLLIN is only

But TCP still calls sk->sk_data_ready() for each chunk added in receive

This patch series add mmap() support to TCP sockets for RX zero copy.
While tcp_mmap() patch itself is quite small (~100 LOC), optimal support
for asynchronous mmap() required better SO_RCVLOWAT behavior, and a
test program to demonstrate how mmap() on TCP sockets can be used.
Note that mmap() (a
Some networks can make sure TCP payload can exactly fit 4KB pages,
with well chosen MSS/MTU and architectures.
Implement mmap() system call so that applications can avoid
copying data without complex splice() games.
Note that a successful mmap( X bytes) on TCP socket is consuming
bytes, as if rec
Applications might use SO_RCVLOWAT on TCP socket hoping to receive
one [E]POLLIN event only when a given amount of bytes are ready in socket
receive queue.
Problem is that receive autotuning is not aware of this constraint,
meaning sk_rcvbuf might be too small to allow all bytes to be stored.
Add
This is a reference program showing how mmap() can be used
on TCP flows to implement receive zero copy.

We should not delay acks if there are not enough bytes
in receive queue to satisfy SO_RCVLOWAT.
Since [E]POLLIN event is not going to be generated, there is little
hope for a delayed ack to be useful.
In fact, delaying ACK prevents sender from completing
the transfer.

Hi Christoph,
I love your patch! Yet something to improve:
