inet: Remove explicit write references to sk/inet in ip_append_data
In order to allow simultaneous calls to ip_append_data on the same
socket, it must not modify any shared state in sk or inet (other

This patch abstracts out write references to sk and inet_sk in
ip_append_data and its friends so that we may use the underlying
code in parallel.

is done by the MC firmware and is not configurable by drivers).

ip_route_newports() is the only place in the entire kernel that

Therefore the only reason we store an entire flow inside of the
struct rtentry is for this one special case.
Rewrite ip_route_newports() such that:
1) The caller passes in the original port values, so we don't need
to use the rth->fl.fl_ip_{s,d}port values to remember them.

iproute2 usage will be 'ip link set ethX vf Y rate Z'.
After the command is made, the rate will be changed instantly.
To view the current rate limit, use 'ip link show ethX'.
The rates will be zeroed only upon driver reload or a link speed change.
This feature is being supported only by 82576 device.

Enhance TIPC to skip unnecessary (and, in some cases, redundant)

tipc: Fix port counter handling to correct congestion control
Modifies TIPC's congestion control between a connected port and its
peer so that it works as documented. The following changes have been
made:
1) The counter of the number of messages sent by a port now starts
at zero, rather than one. This prevents the port from reporting port
congestion one message earlier than it was supposed to.
2) The counter of the number of messages sent by a port is now
incremented only if a non-empty message is sent successfully.
This prevents the port from becoming permanently congested if
too many send attempts are unsuccessful because of congestion
(or other reasons). It also removes the risk that empty hand-
shaking messages used during connection setup might cause the
port to report congestion earlier than it was supposed to.
3) The counter of the number of unacknowledged messages received by
a port controlled by an internal TIPC service is now incremented
only if the message is non-empty, in order to be consistent with
the aforementioned changes.
