The first wrb seen by tx compl processing does not have a dma handle in it.
Currently, pci_unmap_single() is attempted on this wrb and pci_unmap_page() on the
rest. So, pci_unmap_page() gets incorrectly called on the dma hdl of skb->data (that
was mapped using map_single()). This patch fixes this issue.

The counters in the 82599 Virtual Function are not clear on read. They
accumulate to the maximum value and then roll over. They are also not
cleared when the VF executes a soft reset, so it is possible they are
non-zero when the driver loads and starts. This has all been accounted
for in the code that keeps the stats up to date but there is one case
that is not. When the PF driver is reset the counters in the VF are
all reset to zero. This adds an additional accounting overhead into
the VF driver when the PF is reset under its feet. This patch adds
additional counters that are used by the VF driver to accumulate and
save stats after a PF reset has been detected. Prior to this patch
displaying the stats in the VF after the PF has reset would show
bogus data.

bit. Driver must read all other descriptor fields only after reading the

IEEE 802.3ae clause 45 specifies a somewhat modified MDIO protocol
for use by 10GIGE phys. The main change is a 21 bit address split into
a 5 bit device ID and a 16 bit register offset. The definition is designed
so that normal and extended devices can run on the same MDIO bus.
Extend mdio-bitbang to do the new protocol. At the MDIO bus level the
protocol is requested by or'ing MII_ADDR_C45 into the register offset.
Make phy_read/phy_write/etc pass a full 32 bit register offset.
This does not attempt to make the phy layer support C45 style PHYs, just
to provide the MDIO bus support.

This patch fixes UDP socket refcnt bugs in the pppol2tp driver.
A bug can cause a kernel stack trace when a tunnel socket is closed.
A way to reproduce the issue is to prepare the UDP socket for L2TP (by
opening a tunnel pppol2tp socket) and then close it before any L2TP
sessions are added to it. The sequence is
Create UDP socket
Create tunnel pppol2tp socket to prepare UDP socket for L2TP
pppol2tp_connect: session_id=0, peer_session_id=0
L2TP SCCRP control frame received (tunnel_id==0)
pppol2tp_recv_core: sock_hold()
pppol2tp_recv_core: sock_put
L2TP ZLB control frame received (tunnel_id=nnn)
pppol2tp_recv_core: sock_hold()
pppol2tp_recv_core: sock_put
Close tunnel management socket
pppol2tp_release: session_id=0, peer_session_id=0
Close UDP socket
udp_lib_close: BUG
The addition of sock_hold() in pppol2tp_connect() solves the problem.
For data frames, two sock_put() calls were added to plug a refcnt leak
per received data frame. The ref that is grabbed at the top of
pppol2tp_recv_core() must always be released, but this wasn't done for
accepted data frames or data frames discarded because of bad UDP
checksums. This leak meant that any UDP socket that had passed L2TP
data traffic (i.e. L2TP data frames, not just L2TP control frames)
using pppol2tp would not be released by the kernel.
