tcp: fix undo on partial ack in recovery
Upon detecting spurious fast retransmit via timestamps during recovery,
use PRR to clock out new data packet instead of retransmission. Once
all retransmission are proven spurious, the sender then reverts the
cwnd reduction and congestion state to open or disorder.
The current code does the opposite: it undoes cwnd as soon as any
retransmission is spurious and continues to retransmit until all
data are acked. This nullifies the point to undo the cwnd because
the sender is still retransmistting spuriously. This patch fixes
it. The undo_ssthresh argument of tcp_undo_cwnd_reductiuon() is no

This patch series fixes an undo bug in fast recovery: the sender
mistakenly undos the cwnd too early but continues fast retransmits

The first patch prepares the fix by consolidating the accounting

acked and prior_unsacked as const type because they are readonly

MPLS: Add limited GSO support
In the case where a non-MPLS packet is received and an MPLS stack is
added it may well be the case that the original skb is GSO but the
NIC used for transmit does not support GSO of MPLS packets.
The aim of this code is to provide GSO in software for MPLS packets
whose skbs are GSO.
SKB Usage:
When an implementation adds an MPLS stack to a non-MPLS packet it should do
the following to skb metadata:
* Set skb->inner_protocol to the old non-MPLS ethertype of the packet.
skb->inner_protocol is added by this patch.
* Set skb->protocol to the new MPLS ethertype of the packet.
* Set skb->network_header to correspond to the
end of the L3 header, including the MPLS label stack.
I have posted a patch, "[PATCH v3.29] datapath: Add basic MPLS support to
kernel" which adds MPLS support to the kernel datapath of Open vSwtich.
That patch sets the above requirements in datapath/actions.c:push_mpls()
and was used to exercise this code. The datapath patch is against the Open
vSwtich tree but it is intended that it be added to the Open vSwtich code
present in the mainline Linux kernel at some point.
Features:
I believe that the approach that I have taken is at least partially
consistent with the handling of other protocols. Jesse, I understand that
you have some ideas here. I am more than happy to change my implementation.
This patch adds dev->mpls_features which may be used by devices
to advertise features supported for MPLS packets.
A new NETIF_F_MPLS_GSO feature is added for devices which support
hardware MPLS GSO offload. Currently no devices support this
and MPLS GSO always falls back to software.
Alternate Implementation:
One possible alternate implementation is to teach netif_skb_features()
and skb_network_protocol() about MPLS, in a similar way to their
understanding of VLANs. I believe this would avoid the need
for net/mpls/mpls_gso.c and in particular the calls to
__skb_push() and __skb_push() in mpls_gso_segment().
I have decided on the implementation in this patch as it should
not introduce any overhead in the case where mpls_gso is not compiled
into the kernel or inserted as a module.
MPLS GSO suggested by Jesse Gross.

In Lancer, packets that are 32 bytes or less may cause a transmit stall.
The work-around is to pad such packets to a 36 byte length.

bnx2x: Change to D3hot only on removal
This changes the PCI power management scheme of the bnx2x driver to be similar
to those of most network drivers - the driver will now changes the power state
into D3hot whenever the driver will be removed, instead of whenever an
interface is unloaded.
This change enables the driver to access its eeprom via ethtool callbacks
even when interfaces are unloaded (such access requires the function to be
in D0active).

bnx2x: Implement PCI shutdown
Implement the PCI shutdown callback to support un-orderly shutdown, i.e.,
shutdowns in which the remove callback will not be called.
Due to the lack of this functionality, when an un-orderly shutdown occurred,
it was possible for wake-on-lan to remain disabled.
This is now fixed as the callback introduces the correct place in which
`system_state' can be queried and wake-on-lan be configured accordingly.

bnx2x: Count number of possible FCoE interfaces
Commit
0eb43b4bb081a1a22574daab9c05286a600dd7fe
"bnx2x, bnx2fc: Use per port max exchange resources" has changed the number
of available FCoE exchanges, even in scenarios when some of the functions has
no FCoE support; This needlessly degraded the available resources.
Remedy this by calculating the maximal number of functions that may actually
utilize said connection.

A PF should ack the firmware when receiving unknown messages through the VF's
