A linkgroup might be terminated while normal connection closing
is running. Avoid buffer reuse and its related LLC DELETE RKEY

Extend the size of QSFP EEPROM for the cable types SSF8436 and SFF8636
from 256 to 640 bytes in order to expose all the EEPROM pages by
ethtool.
For SFF-8636 and SFF-8436 specifications, the driver exposes 256 bytes
of data for ethtool's get_module_eeprom() callback. This is because the
driver uses the below defines to specify SFF module length in ethtool's
get_module_info() callback:
'ETH_MODULE_SFF_8636_LEN' and 'ETH_MODULE_SFF_8436_LEN' (both are 256).
As a result of exposing 256 bytes only, ethtool shows wrong "zero" info
for pages 1, 2, 3.
The patch changes the length returned by callback for get_module_info()
to the values from the next defines: 'ETH_MODULE_SFF_8636_MAX_LEN' and
'ETH_MODULE_SFF_8436_MAX_LEN' (both are 640) to allow exposing of upper
page 1, 2 and 3.

1GbE Intel Wired LAN Driver Updates 2019-10-21
This series contains updates to e1000e and igc only.
Sasha adds stream control transmission protocol (SCTP) CRC checksum
support for igc. Also added S0ix support to the e1000e driver. Then
added multicast support by adding the address list to the MTA table and
providing the option for IPv6 address for igc. In addition, added
receive checksum support to igc as well. Lastly, cleaned up some code
that was not fully implemented yet for the VLAN filter table array.
v2: Dropped patch 1 & 2 from the original series. Patch 1 is being sent
to 'net' tree as a fix and patch 2 implementation needs to be
re-worked. Updated the patch to add support for S0ix to fix the
reverse Xmas tree issues and made the entry/exit functions void
since they constantly returned success. All based on community
feedback.
v3: Cleaned up patch 4 of the series based on feedback from the
community. Cleaned up a stray comma in a code comment and removed
the 'inline' of a function that would be inlined by the compiler
anyways.

add XDP support to mvneta driver
Add XDP support to mvneta driver for devices that rely on software
buffer management. Supported verdicts are:
- XDP_DROP
- XDP_PASS
- XDP_REDIRECT
- XDP_TX
Moreover set ndo_xdp_xmit net_device_ops function pointer in order
to support redirecting from other device (e.g. virtio-net).
Convert mvneta driver to page_pool API.
This series is based on previous work done by Jesper and Ilias.
We will send follow-up patches to reduce DMA-sync operations.
Changes since v4:
- reset page_pool pointer to NULL in mvneta_rxq_drop_pkts and in
mvneta_create_page_pool error path
- move dma sync in mvneta_rx_refill() in patch 2/7
- verify bpf prog pointer in mvneta_xdp_setup to double-check if
stop/start is really necessary
- coding style fixes
Changes since v3:
- rename MVNETA_XDP_CONSUMED in MVNETA_XDP_DROPPED
- squash patch 4/8 and patch 3/8
- fix dma sync for XDP_TX verdict
- fix queue_index in xdp_rxq_info_reg
- cosmetics
Changes since v2:
- rely on page_pool_recycle_direct instead of xdp_return_buff for XDP_DROP
- define xdp buffer in mvneta_rx_swbm and avoid default initializations
- use dma_sync_single_for_cpu instead of dma_sync_single_range_for_cpu
- run page_pool_release_page in mvneta_swbm_add_rx_fragment even if
the buffer contains just ETH_FCS
Changes since v1:
- sync dma buffers before refilling hw queues
- fix stats accounting
Changes since RFC:
- implement XDP_TX
- make tx pending buffer list agnostic
- code refactoring
- check if device is running in mvneta_xdp_setup

Refactor mvneta_rx_swbm code introducing mvneta_swbm_rx_frame and
mvneta_swbm_add_rx_fragment routines. Rely on build_skb in oreder to
allocate skb since the previous patch introduced buffer recycling using
the page_pool API.
This patch fixes even an issue in the original driver where dma buffers
are accessed before dma sync.
mvneta driver can run on not cache coherent devices so it is
necessary to sync DMA buffers before sending them to the device
in order to avoid memory corruptions. Running perf analysis we can
see a performance cost associated with this DMA-sync (anyway it is
already there in the original driver code). In follow up patches we
will add more logic to reduce DMA-sync as much as possible.

Intel test robot reported a ~7% regression on TCP_CRR tests
that they bisected to the cited commit.
Indeed, every time a new TCP socket is created or deleted,
the atomic counter net->count is touched (via get_net(net)
and put_net(net) calls)
So cpus might have to reload a contended cache line in
net_hash_mix(net) calls.
We need to reorder 'struct net' fields to move @hash_mix
in a read mostly cache line.
We move in the first cache line fields that can be
dirtied often.
We probably will have to address in a followup patch
the __randomize_layout that was added in linux-4.13,
since this might break our placement choices.
