tcp listener refactoring part 15
I am trying to make the final patch pushing request socks into ehash
as small as possible. In this patch series, I made various adjustments
for the SYNACK generation, allowing me to reach 1 Mpps SYNACK in my
stress test (still hitting LISTENER spinlock of course, and the syn_wait
spinlock)
I also converted the ICMP handlers a bit ahead of time :
They no longer need to get the LISTENER socket, and can use
only a lookup in ehash table. No big deal if we ignore ICMP
for requests socks before the final steps.

listener can be source of false sharing. request sock has some
useful information like : ireq->ir_iif, ireq->ir_num, ireq->ireq_net
This patch does not solve the major problem of having to read
sk->sk_protocol which is sharing a cache line with sk->sk_wmem_alloc.
(This same field is read later in ip_build_and_send_pkt())
One idea would be to move sk_protocol close to sk_family
(using 8 bits instead of 16 for sk_family seems enough)

When a device with an isochronous endpoint is plugged into the Intel
xHCI host controller, and the driver submits multiple frames per URB,
the xHCI driver will set the Block Event Interrupt (BEI) flag on all
but the last TD for the URB. This causes the host controller to place
an event on the event ring, but not send an interrupt. When the last
TD for the URB completes, BEI is cleared, and we get an interrupt for
the whole URB.
However, under Intel xHCI host controllers, if the event ring is full
of events from transfers with BEI set, an "Event Ring is Full" event
will be posted to the last entry of the event ring, but no interrupt
is generated. Host will cease all transfer and command executions and
wait until software completes handling the pending events in the event
ring. That means xHC stops, but event of "event ring is full" is not
notified. As the result, the xHC looks like dead to user.
This patch is to apply XHCI_AVOID_BEI quirk to Intel xHC devices. And
it should be backported to kernels as old as 3.0, that contains the
commit 69e848c209 ("Intel xhci: Support EHCI/xHCI port switching.").

Linux xHCI driver doesn't report and handle port cofig error change.
If Port Configure Error for root hub port occurs, CEC bit in PORTSC
would be set by xHC and remains 1. This happends when the root port
fails to configure its link partner, e.g. the port fails to exchange
port capabilities information using Port Capability LMPs.
Then the Port Status Change Events will be blocked until all status
change bits(CEC is one of the change bits) are cleared('0') (refer to
xHCI spec 4.19.2). Otherwise, the port status change event for this
root port will not be generated anymore, then root port would look
like dead for user and can't be recovered until a Host Controller
Reset(HCRST).
This patch is to check CEC bit in PORTSC in xhci_get_port_status()
and set a Config Error in the return status if CEC is set. This will
cause a ClearPortFeature request, where CEC bit is cleared in
xhci_clear_port_change_bit().

removes "WARN_ON(!ops->ndo_switch_parent_id_get)" because
direct bridge ports can be stacked netdevices (like bonds

skb->priority can be set for two purposes:
1) With respect to IP TOS field, which is computed by a mask.
Ususally used for priority qdisc's (pfifo, prio etc.), on TX
side (we only have ingress qdisc on RX side).
2) Used as a classid or flowid, works in the same way with tc
classid. What's more, this can even override the classid
of tc filters.
For case 1), it has been respected within its netns, I don't
see any point of keeping it for another netns, especially
when packets will be forwarded to Rx path (no matter from TX
path or RX path).
For case 2) we care, our applications run inside a netns,
and we classify the packets by our own filters outside,
If some application sets this priority, it could bypass
our filters, therefore clear it when moving out of a netns,
it makes no sense to bypass tc filters out of its netns.

Add support for async socket operations
After the iocb parameter has been removed from sendmsg() and recvmsg() ops
the socket layer, and the network stack no longer support async operations.
This patch set adds support for asynchronous operations on sockets back.
Changes in v3:
* As sugested by Al Viro instead of adding new functions aio_sendmsg
and aio_recvmsg, added a ptr to iocb into the kernel-side msghdr structure.
This way no change to aio.c is required.
Changes in v2:

The way the algif_skcipher works currently is that on sendmsg/sendpage it
builds an sgl for the input data and then on read/recvmsg it sends the job
for encryption putting the user to sleep till the data is processed.
This way it can only handle one job at a given time.
This patch changes it to be asynchronous by adding AIO support.
