The r8169 driver supports 3 different families of network chips
(RTL8169, RTL8168 and RTL8101). When an unknown version is found, the

little chance to ever work for chips of the other families. So better
define a per-family default.

ixgbe_probe() - moving the check for IXGBE_ERR_SFP_NOT_PRESENT from

igb: Record host memory receive overflow in net_stats
Based on previous patch from Jesper Dangaard Brouer.
The RNBC (Receive No Buffers Count) register for the 82576, indicate
that frames were received when there were no available buffers in host
memory to store those frames (receive descriptor head and tail
pointers were equal). The packet is still received by the NIC if
there is space in the FIFO on the NIC.
As the RNBC value is not a packet drop, the driver stores this value
in net_stats.rx_fifo_errors to indicate that there were no system
buffers available for the incoming packet. Actual dropped packets
are counted in the MPC value.
Saving the stats in dev->net_stats makes it visible via
/proc/net/dev as "fifo", and thus viewable to ifconfig
as "overruns" and 'netstat -i' as "RX-OVR".
The Receive No Buffers Count (RNBC) can already be queried by
ethtool -S as "rx_no_buffer_count".

Since commit
0fd56bb5be6455d0d42241e65aed057244665e5e ("gianfar:
Add support for skb recycling"), gianfar puts skbuffs that are in
the rx ring back onto the recycle list as-is in case there was a
receive error, but this breaks the following invariant: that all
skbuffs on the recycle list have skb->data = skb->head + NET_SKB_PAD.
The RXBUF_ALIGNMENT realignment done in gfar_new_skb() will be done
twice on skbuffs recycled in this way, causing there not to be enough
room in the skb anymore to receive a full packet, eventually leading
to an skb_over_panic from gfar_clean_rx_ring() -> skb_put().
Resetting the skb->data pointer to skb->head + NET_SKB_PAD before
putting the skb back onto the recycle list restores the mentioned
invariant, and should fix this issue.

Hi:
skbuff: Move new __skb_clone code into __copy_skb_header
It seems that people just keep on adding stuff to __skb_clone
instead __copy_skb_header. This is wrong as it means your brand-new
attributes won't always get copied as you intended.
This patch moves them to the right place, and adds a comment to
prevent this from happening again.

dropmon: add ability to detect when hardware dropsrxpackets
Patch to add the ability to detect drops in hardware interfaces via dropwatch.
Adds a tracepoint to net_rx_action to signal everytime a napi instance is
polled. The dropmon code then periodically checks to see if the rx_frames
counter has changed, and if so, adds a drop notification to the netlink
protocol, using the reserved all-0's vector to indicate the drop location was in
hardware, rather than somewhere in the code.
