This new function wants to access and set some rx_ring parameters, but
adapter->rx_ring has already been freed. This simply moves the free

but it is bad enough that we should probably just disable netpoll over

When building tx command, always set TX_CMD_FLAG_PROT_REQUIRE_MSK

Without setting this bit the firmware will not examine the RTS/CTS setting

Similar to 6000 and 1000 series, RTS/CTS is the recommended
protection mechanism for 5000 series in HT mode based on the HW design.
Using RTS/CTS will better protect the inner exchange from interference,
especially in highly-congested environment, it also prevent uCode encounter
TX FIFO underrun and other HT mode related performance issues.

iwlwifi: apply filter flags directly
broke multicast. The reason, it turns out, is that
the code previously checked if ALLMULTI _changed_,
which the new code no longer did, and normally it
_never_ changes. Had somebody changed it manually,
the code prior to my patch there would have been
broken already.
The reason is that we always, unconditionally, ask
the device to pass up all multicast frames, but the
new code made it depend on ALLMULTI which broke it
since now we'd pass up multicast frames depending
on the default filter in the device, which isn't
necessarily what we want (since we don't program it
right now).
Fix this by simply not checking allmulti as we have
allmulti behaviour enabled already anyway.

There are few places where ANI is started without checking
if it is right to start. This might lead to a case where ani
timer would be left undeleted and cause improper memory acccess
during module unload. This bug is clearly exposed with
paprd support where the driver detects tx hang and does a
chip reset. During this reset ani is (re)started without checking
if it needs to be started. This would leave a timer scheduled
even after all the resources are freed and cause a panic.
This patch introduces a bit in sc_flags to indicate if ani
needs to be started in sw_scan_start() and ath_reset().
This would fix the following panic. This issue is easily seen
with ar9003 + paprd.

This removes dma_get_ops() prefetch optimization in bnx2.
bnx2 uses dma_get_ops() to see if dma_sync_single_for_cpu() is
noop. bnx2 does prefetch if it's noop.
But dma_get_ops() isn't available on all the architectures (only the
architectures that uses dma_map_ops struct have it). Using
dma_get_ops() in drivers leads to compilation breakage on many
architectures.
This patch removes dma_get_ops() and changes bnx2 to do prefetch on
all the architectures. This adds useless prefetch on non-coherent
architectures but this is harmless. It is also unlikely to cause the
performance drop.

Dumped buffer descriptors showed that eTSEC's length/truncation
logic sometimes passes oversized packets, i.e. for the above ICMP
packet the following two buffer descriptors may become ready:
status=1400 length=1536
status=1800 length=1541
So, it seems that gianfar actually receives the whole big frame,
and it tries to place the packet into two BDs. This situation
confuses the driver, and so the skb_put() sanity check fails.
This patch fixes the issue by adding an appropriate check, i.e.
the driver should not try to process frames with buffer
descriptor's length over rx_buffer_size (i.e. maxfrm and mrblr).
Note that sometimes eTSEC works correctly, i.e. in the second
(last) buffer descriptor bits 'truncated' and 'crcerr' are set,
and so there's no oops. Though I couldn't find any logic when
it works correctly and when not.

Previously the RCTRL_TS_ENABLE bit was set unconditionally. However, if
the RCTRL_TS_ENABLE is set without TMR_CTRL[TE], the driver does not work
properly on some boards (Anton had problems with the MPC8313ERDB and
MPC8568EMDS).
With this patch the bit will only be set if requested from user space
with the SIOCSHWTSTAMP ioctl command, meaning that time stamping is
disabled during normal operation. Users who are not interested in time
stamps will not experience problems with buggy CPU revisions or
performance drops any more.
The setting of TMR_CTRL[TE] is still up to the user. This is considered
safe because users wanting HW timestamps must initialize the eTSEC clock
first anyway, e.g. with the recently submitted PTP clock driver.

of the queue from which the aggregated packets were sent. However, in
some hardware like the 1000 series, sometimes the flow id is 0 for the
txq_id (10 to 19). This can cause the annoying message:

And even worse, if agg->wait_for_ba is true when the bad BA is arriving,
this can cause system hang due to NULL pointer dereference because the

ixgbe: enable extremely low latency
introduced a feature where LRO (called RSC on the hardware) was disabled
automatically when setting rx-usecs to 0 via ethtool. Some might not
like the fact that LRO was disabled automatically, but I'm fine with
that. What I don't like is that LRO/RSC is automatically enabled when
rx-usecs is set >0 via ethtool.
This would certainly be a problem if the device was used for forwarding
and it was determined that the low latency wasn't needed after the
device was already forwarding. I played around with saving the state of
LRO in the driver, but it just didn't seem worthwhile and would require
a small change to dev_disable_lro() that I did not like.
This patch simply leaves LRO disabled when setting rx-usecs >0 and
requires that the user enable it again. An extra informational message
will also now appear in the log so users can understand why LRO isn't
being enabled as they expect.
Inconsistency of LRO setting first noticed by Stanislaw Gruszka.

Since commit cc772ab7cd ("gianfar: Add
hardware RX timestamping support"), the driver no longer works on
at least MPC8313ERDB and MPC8568EMDS boards (and possibly much more
boards as well).
That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit:
Timestamp incoming packets as padding bytes. PAL field is set
to 8 if the PAL field is programmed to less than 8. Must be set
to zero if TMR_CTRL[TE]=0.
I see that the commit above sets this bit, but it doesn't handle
TMR_CTRL. Manfred probably had this bit set by the firmware for
his boards. But obviously this isn't true for all boards in the
wild.
Also, I recall that Freescale BSPs were explicitly disabling the
timestamping because of a performance drop.
For now, the best way to deal with this is just disable the
timestamping, and later we can discuss proper device tree bindings
and implement enabling this feature via some property.
