While implementing NAPI for the driver, I overlooked the race conditions where
interrupt handler might have called napi_schedule_prep() before napi_enable()
was called or after napi_disable() was called. If RX interrupt happens, this
would cause the endless interrupts and messages like:
sh-eth eth0: ignoring interrupt, status 0x00040000, mask 0x01ff009f.
The interrupt wouldn't even be masked by the kernel eventually since the handler
would return IRQ_HANDLED all the time.
As a fix, move napi_enable() call before request_irq() call and napi_disable()
call after free_irq() call.

Bug: error to get the previous BD entry. When the current BD
is the first BD, the previous BD entry must be the last BD,
not "bdp - 1" in current logic.
V4:
* Optimize fec_enet_get_nextdesc() for code clean.
Replace "ex_new_bd - ring_size" with "ex_base".
Replace "new_bd - ring_size" with "base".
V3:
* Restore the API name because David suggest to use fec_enet_
prefix for all function in fec driver.
So, change next_bd() -> fec_enet_get_nextdesc()
change pre_bd() -> fec_enet_get_prevdesc()
* Reduce the two APIs parameters for easy to call.
V2:
* Add tx_ring_size and rx_ring_size to struct fec_enet_private.
* Replace api fec_enet_get_nextdesc() with next_bd().
Replace api fec_enet_get_prevdesc() with pre_bd().
* Move all ring size check logic to next_bd() and pre_bd(), which
simplifies the code redundancy.

Fix xgmac_set_rx_mode to handle several conditions that were not handled
correctly as Lennert Buytenhek describes:
If we have, say, 100 unicast addresses, and 5 multicast addresses, the
unicast address count check will evaluate to true, and set use_hash to
true. The multicast address check will however evaluate to false, and
use_hash won't be set to true again, and XGMAC_FRAME_FILTER_HMC won't
be OR'd into XGMAC_FRAME_FILTER, but since use_hash was still true
from the unicast check, netdev_for_each_mc_addr() will program the
multicast addresses into the hash table instead of using the MAC
address registers, but since the HMC bit wasn't set, the hash table
won't be checked for multicast addresses on receive, and we'll stop
receiving multicast packets entirely.
Also, there is no code that zeroes out MAC address registers reg..31
at the end of this function, meaning that under the right conditions,
unicast/multicast addresses that were previously in the filter but
were then deleted won't be cleared out.

Since the xgmac transmit start and completion work locklessly, it is
possible for xgmac_xmit to stop the tx queue after the xgmac_tx_complete
has run resulting in the tx queue never being woken up. Fix this by
ensuring that ring buffer index updates are visible and recheck the ring
space after stopping the queue. Also fix an off-by-one bug where we need
to stop the queue when the ring buffer space is equal to MAX_SKB_FRAGS.
The implementation used here was copied from
drivers/net/ethernet/broadcom/tg3.c.

The TX completion code may have freed an skb before the entire sg list
was transmitted. The DMA unmap calls for the fragments could also get
skipped. Now set the skb pointer on every entry in the ring, not just
the head of the sg list. We then use the FS (first segment) bit in the
descriptors to determine skb head vs. fragment.
This also fixes similar bug in xgmac_free_tx_skbufs where clean-up of
a sg list that wraps at the end of the ring buffer would not get
unmapped.

Fix the amount of sent bytes reported to BQL by reporting the
number of bytes on wire in the xmit routine, and recording that
value for each skb in order to be correctly confirmed on Tx
confirmation cleanup.
Reporting skb->len to BQL just before exiting xmit is not correct
due to possible insertions of TOE block and alignment bytes in the
skb->data, which are being stripped off by the controller before
transmission on wire. This led to mismatch of (incorrectly)
reported bytes to BQL b/w xmit and Tx confirmation, resulting in
Tx timeout firing, for the h/w tx timestamping acceleration case.
There's no easy way to obtain the number of bytes on wire in the Tx
confirmation routine, so skb->cb is used to convey that information
from xmit to Tx confirmation, for now (as proposed by Eric). Revived
the currently unused GFAR_CB() construct for that purpose.

We're using it currently to verify if we have vlans before getting the tag
from the skb we're about to send. It's useless because the vlan_get_tag()
verifies if the skb has the tag (and returns an error if not), and we can
receive tagged skbs only if we *already* have vlans.
Plus, the current RCUed implementation is kind of useless anyway - the we
can remove the last vlan in the moment we return from the function.
So remove the only usage of it and the whole function.

====================

John W. Linville says:
====================
Please accept this batch of updates intended for the 3.12 stream.
For the mac80211 bits, Johannes says this:
"This time I have various improvements all over the place: IBSS, mesh,
testmode, AP client powersave handling, one of the rare rfkill patches
and some code cleanup."
Also for mac80211:
"And I also have some more changes for -next, just a few small fixes and
improvements, nothing really stands out."
And for iwlwifi:
"This time I have some powersave work (notably uAPSD support), CQM
offloads, support for a new firmware API and various code cleanups."
Regarding the Bluetooth bits, Gustavo says:
"Patches to 3.12, here we have:
* implementation of a proper tty_port for RFCOMM devices, this fixes some
issues people were seeing lately in the kernel.
* Add voice_setting option for SCO, it is used for SCO Codec selection
* bugfixes, small improvements and clean ups"
For the NFC bits, Samuel says:
"With this one we have:
- A few pn533 improvements and minor fixes. Testing our pn533 driver
against Google's NCI stack triggered a few issues that we fixed now.
We also added Tx fragmentation support to this driver.
- More NFC secure element handling. We added a GET_SE netlink command
for getting all the discovered secure elements, and we defined 2
additional secure element netlink event (transaction and connectivity).
We also fixed a couple of typos and copy-paste bugs from the secure
element handling code.
- Firmware download support for the pn544 driver. This chipset can enter a
special mode where it's waiting for firmware blobs to replace the
already flashed one. We now support that mode."
With repect to the ath tree, Kalle says:
"New features in ath10k are rx/tx checsumming in hw and survey scan
implemented by Michal. Also he made fixes to different areas of the
driver, most notable being fixing the case when using two streams and
reducing the number of interface combinations to avoid firmware crashes.
Bartosz did a clean related to how we handle SoC power save in PCI
layer.
For ath6kl Mohammed and Vasanth sent each a patch to fix two infrequent
crashes."
I also pulled the wireless tree into wireless-next to support a
request from Johannes. On top of all that, there are the usual
sort of driver updates. The mwifiex, brcmfmac, brcmsmac, ath9k,
and rt2x00 drivers all get some attention, as does the bcma bus and
a few other random bits here and there.

If the VIRTIO_NET_F_GUEST_CSUM virtio feature is available, the guest
does not have to calculate the checksums on all received packets. This
is pretty much the same feature as RX checksum offloading on real
network cards, so the virtio-net driver should report this by setting
the NETIF_F_RXCSUM flag. When the user now runs "ethtool -k", he or she
can see whether the virtio-net interface has to calculate RX checksums
or not.
