If a guest is destroyed without transitioning its frontend to CLOSED,
the domain becomes a zombie as netback was not grant unmapping the
shared rings.

When removing a VIF, transition the backend to CLOSED so the VIF is
disconnected if necessary (which will unmap the shared rings etc).

This fixes a regression introduced by
279f438e (xen-netback: Don't destroy
the netdev until the vif is shut down).

This patch fixes a bug introduced by commit 51151a16 (mlx4: allow
order-0 memory allocations in RX path).

dma_unmap_page never reached because condition to detect last fragment
in page is wrong. offset+frag_stride can't be greater than size, need to
make sure no additional frag will fit in page => compare offset +
frag_stride + next_frag_size instead.
next_frag_size is the same as the current one, since page is shared only
with frags of the same size.

Currently, in TLB mode we change mac addresses only by memcpy-ing the to
net_device->dev_addr, without actually setting them via
dev_set_mac_address(). This permits us to receive all the traffic always on
one mac address.

However, in case the interface flips, some drivers might enforce the
mac filtering for its FW/HW based on current ->dev_addr, and thus we won't
be able to receive traffic on that interface, in case it will be selected
as active in TLB mode.

Fix it by setting the mac address forcefully on every new active slave that
we select in TLB mode.

This patch will fix RX packets errors when receiving big size
of data by set bit RNC = 1.

RNC - Receive Enable Control

0: Upon completion of reception of one frame, the E-DMAC writes
the receive status to the descriptor and clears the RR bit in
EDRRR to 0.

1: Upon completion of reception of one frame, the E-DMAC writes
(writes back) the receive status to the descriptor. In addition,
the E-DMAC reads the next descriptor and prepares for reception
of the next frame.

In addition, for get more stable when receiving packets, I set
maximum size for the transmit/receive FIFO and inserts padding
in receive data.

The mrf24j40 generates level interrupts. There are rare cases where it
appears that the interrupt line never gets de-asserted between interrupts,
causing interrupts to be lost, and causing a hung device from the driver's

level-triggered fixes this issue.

Although we do not yet enable multiple PFs per port, it is possible
that a board will be reconfigured to enable them while the driver has
not yet been updated to fully support this.

The most obvious problem is that multiple functions may try to set
conflicting link settings.  But we will also run into trouble if the
firmware doesn't consider us fully trusted.  So, abort probing unless
both the LinkCtrl and Trusted flags are set for this function.

Recognise the new Packet Memory and RX Data Path counters.

The following counters are added:
rx_pm_{trunc,discard}_bb_overflow - burst buffer overflowed.  This should not
 occur if BB correctly configured.
rx_pm_{trunc,discard}_vfifo_full - not enough space in packet memory.  May
 indicate RX performance problems.
rx_pm_{trunc,discard}_qbb - dropped by 802.1Qbb early discard mechanism.
 Since Qbb is not supported at present, this should not occur.
rx_pm_discard_mapping - 802.1p priority configured to be dropped.  This should
 not occur in normal operation.
rx_dp_q_disabled_packets - packet was to be delivered to a queue but queue is
 disabled.  May indicate misconfiguration by the driver.
rx_dp_di_dropped_packets - parser-dispatcher indicated that a packet should be
 dropped.
rx_dp_streaming_packets - packet was sent to the RXDP streaming bus, ie. a
 filter directed the packet to the MCPU.
rx_dp_emerg_{fetch,wait} - RX datapath had to wait for descriptors to be
 loaded.  Indicates performance problems but not drops.

These are only provided if the MC firmware has the
PM_AND_RXDP_COUNTERS capability.  Otherwise, mask them out.

Previously, efx_ef10_stat_mask returned a static const unsigned long[], which
meant that each possible mask had to be declared statically with
STAT_MASK_BITMAP.  Since adding a condition would double the size of the
decision tree, we now create the bitmask dynamically.

To do this, we have two functions efx_ef10_raw_stat_mask, which returns a u64,
and efx_ef10_get_stat_mask, which fills in an unsigned long * argument.

This patch allows (optionally, via ethtool) the atl1e NIC to:
- Receive bad frames (runt, bad-fcs, etc..)
- Receive full frames without stripping the FCS.

This has been tested on my board by injecting runt and bad-fcs
frames with a FPGA-based device.

The particular scenario of receiving very short frames (<4 bytes)
without passing FCS to the upper layer has been also tested:
This could be potentially dangerous because the driver performs a
4 byte subtraction on the frame length, but I finally have NOT
added anything to avoid this because it seems the NIC always
discards frames so much short..
If someone still have some reason to worry about this, please
tell me.. I will add an explicit SW check..
