Commit dc975382 "net: fec: add napi support to improve proformance"
converted the fec driver to the napi model. However, that commit
forgot to remove the call to skb_defer_rx_timestamp which is only
needed in non-napi drivers.
(The function napi_gro_receive eventually calls netif_receive_skb,
which in turn calls skb_defer_rx_timestamp.)
This patch should also be applied to the 3.9 and 3.10 kernels.

My static checker complains that on some arches unsigned longs can be 8
characters which is larger than the buffer is only 6 chars.
Additionally, Ben Hutchings points out that the buffer actually holds
big endian data and the buffer we are reading from is CPU endian.

__GFP_ZERO is an uncommon flag and perhaps is better
not used. static inline dma_zalloc_coherent exists
so convert the uses of dma_alloc_coherent with __GFP_ZERO
to the more common kernel style with zalloc.
Remove memset from the static inline dma_zalloc_coherent
and add just one use of __GFP_ZERO instead.
Trivially reduces the size of the existing uses of
dma_zalloc_coherent.
Realign arguments as appropriate.

Jeff Kirsher says:
====================
This series contains updates to ixgbe.
Jacob provides a fix for 82599 devices where it can potentially keep link
lights up when the adapter has gone down.
Mark provides a fix to resolve the possible use of uninitialized memory
by checking the return value on EEPROM reads.
Don provides 2 patches, one to fix a issue where we were traversing the
Tx ring with the value of IXGBE_NUM_RX_QUEUES which currently happens
to have the correct value but this is misleading. A change later, could
easily make this no longer correct so when traversing the Tx ring, use
netdev->num_tx_queues. His second patch does some minor clean ups of log
messages.
Emil provides the remaining ixgbe patches. First he fixes the link test
where forcing the laser before the link check can lead to inconsistent
results because it does not guarantee that the link will be negotiated
correctly. Then he initializes the message buffer array to 0 in order
to avoid using random numbers from the memory as a MAC address for the
VF. Emil also fixes the read loop for the I2C data to account for the
offset for SFP+ modules. Lastly, Emil provides several patches to add
support for QSFP modules where 1Gbps support is added as well as support
for older QSFP active direct attach cables which pre-date SFF-8436 v3.6.
v2: Fixed patch 4 description and added blank line based on feedback from

This adds support for the EF10 network controller architecture and the
SFC9100 family, starting with SFC9120 'Farmingdale', and bumps the
driver version to 4.0.
New features in the SFC9100 family include:
- Flexible allocation of internal resources to PCIe physical and virtual
functions under firmware control
- RX event merging to reduce DMA writes at high packet rates
- Integrated RX timestamping
- PIO buffers for lower TX latency
- Firmware-driven data path that supports additional offload features
and filter types
- Delivery of packets between functions and to multiple recipients,
allowing firmware to implement a vswitch
- Multiple RX flow hash (RSS) contexts with their own hash keys and
indirection tables
- 40G MAC (single port only)
...not all of which are enabled in this initial driver or the initial
firmware release.
Much of the new code is by Jon Cooper.

Also update comments and assertions in io.h:
- EF10 does not have a general BIU collector and does not have the
bug affecting TIMER_COMMAND_REG[0] on Falcon/Siena
- The WPTR field moved within RX_DESC_UPD_REG and TX_DESC_UPD_REG.

The TX path firmware for EF10 supports 'option descriptors' to control
offloads and various other features. Add a flag and field for these
in struct efx_tx_buffer, and don't treat them as DMA descriptors on
completion.

On EF10, the firmware will initiate a queue flush in certain
error cases. We need to accept that flush events might appear
at any time after a queue has been initialised, not just when
we try to flush them.
We can handle Falcon-architecture in just the same way.

RX DMA scatter is always enabled on EF10. Adjust the common RX
completion handling to allow for this.
RX completion events on EF10 include the length used from a single
descriptor, not the cumulative length used. Add a field to struct
efx_rx_queue to hold the cumulative length.
