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

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

Saving the stats in dev->net_stats makes it visible via

packets dropped by a queue due to lack of descriptors available.
Notice RQDPC (Receive Queue Drop Packet Count) stats only gets
incremented, if the DROP_EN bit it set (in the SRRCTL register
for that queue). If DROP_EN bit is NOT set, then the some what
equivalent count is stored in RNBC (not per queue basis).
The RQDPC register is only 12 bit, thus the precision might
suffer due to overrun in-netween the watchdog polling interval.

Some devices, (particularly loopback) dont need trans_start update, because
they dont have transmit watchdog. We could add a new device flag, or rely

r8169: avoid losing MSI interrupts
The 8169 chip only generates MSI interrupts when all enabled event
sources are quiescent and one or more sources transition to active. If
not all of the active events are acknowledged, or a new event becomes
active while the existing ones are cleared in the handler, we will not
see a new interrupt.
The current interrupt handler masks off the Rx and Tx events once the
NAPI handler has been scheduled, which opens a race window in which we
can get another Rx or Tx event and never ACK'ing it, stopping all
activity until the link is reset (ifconfig down/up). Fix this by always
ACK'ing all event sources, and loop in the handler until we have all
sources quiescent.

netfilter: nf_ct_tcp: fix accepting invalid RST segments
Robert L Mathews discovered that some clients send evil TCP RST segments,
which are accepted by netfilter conntrack but discarded by the
destination. Thus the conntrack entry is destroyed but the destination
retransmits data until timeout.
The same technique, i.e. sending properly crafted RST segments, can easily
be used to bypass connlimit/connbytes based restrictions (the sample
script written by Robert can be found in the netfilter mailing list
archives).
The patch below adds a new flag and new field to struct ip_ct_tcp_state so
that checking RST segments can be made more strict and thus TCP conntrack
can catch the invalid ones: the RST segment is accepted only if its
sequence number higher than or equal to the highest ack we seen from the
other direction. (The last_ack field cannot be reused because it is used
to catch resent packets.)

gianfar: fix BUG under load after introduction of skb recycling
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.

iwlwifi: check for valid band for channel info
when display channel info in debugfs, always check for valid band
before access the pointer and display information
for 1000 NIC, it only support "bgn" mode, so there is no 5.2GHz channels
available to display.

iwlcore: Add support for periodic RX interrupt
Periodic RX interrupt needed with ICT interrupt to prevent RX race.
Sending RX interrupt require many steps to be done in the
the device:
1- write interrupt to current index in ICT table.
2- dma RX frame.
3- update RX shared data to indicate last write index.
4- send interrupt.
This could lead to RX race, driver could receive RX interrupt
but the shared data changes does not reflect that.
this could lead to RX race, RX periodic will solve this race

iwlcore: Allow skb allocation from tasklet.
If RX queue becomes empty then we need to restock the queue from tasklet to prevent
ucode from starving. A caller to iwl_rx_allocate will decide if allocated buffer should
come from GFP_ATOMIC or GFP_KERNEL.
