40GbE Intel Wired LAN Driver Updates 2018-08-07

This series contains updates to i40e and i40evf only.

Sergey cleans up a duplicate call to i40e_prep_for_reset() during
shutdown.

YueHaibing cleans up i40evf by removing code that was never being used
or called within the driver.

Jake updates the ethtool statistics to use a helper function since many
of the statistics use the same basic logic for copying strings into the
supplied buffer.  Cleaned up the use of a local variable that is no
longer needed or used.  Fixed additional stats issues, including the
failure to update the data pointer which was causing stats to be
reported incorrectly.

Mariusz fixes a bug where there was an oversight in configuring FEC when
link settings were forced which was causing 25G link to be configured
incorrectly.

Piotr adds a missing return code for when the firmware returns a busy
state.  Also added the process to command firmware to start
rearrangement when switching between old NVM structure to the new flat
NVM.

qed: Add Multi-TC RoCE support

This patch series adds support for multiple concurrent traffic classes for RoCE.
The first three patches enable the required parts of the driver to learn the TC
configuration, and the last one makes use of it to enable the feature.
Please consider applying this to net-next.

V1->V2:
-------
Avoid allocation in qed_dcbx_get_priority_tc().
Move qed_dcbx_get_priority_tc() out of CONFIG_DCB section since it doesn't call
qed_dcbx_query_params() anymore.

v2->V3:
-------
patch 1/3:
qed_dcbx_get_priority_tc() always returns a valid TC by value. In error cases,
it returns QED_DCBX_DEFAULT_TC (currently defined 0).
patch 3/3:
Cosmetic changes in qed_dev.c.

RoCE qps use a pair of physical queues (pq) received from the Queue Manager
(QM) - an offload queue (OFLD) and a low latency queue (LLT). The QM block
creates a pq for each TC, and allows RoCE qps to ask for a pq with a
specific TC. As a result, qps with different VLAN priorities can be mapped
to different TCs, and employ features such as PFC and ETS.

net: macb: add pad and fcs support

In [1] it was reported that UDP checksum is offloaded to hardware no mather
it was previously computed in software or not. The proposal on [1] was to
disable TX checksum offload.

This series (mostly patch 3/3) address the issue described at [1] by
setting NOCRC bit to TX buffer descriptor for SKBs that arrived from
networking stack with checksum computed. For these packets padding and FCS
need to be added (hardware doesn't compute them if NOCRC bit is set). The
minimum packet size that hardware expects is 64 bytes (including FCS).
This feature could not be used in case of GSO, so, it was used only for
no GSO SKBs.

For SKBs wich requires padding and FCS computation macb_pad_and_fcs()
checks if there is enough headroom and tailroom in SKB to avoid copying
SKB structure. Since macb_pad_and_fcs() may change SKB the
macb_pad_and_fcs() was places in macb_start_xmit() b/w macb_csum_clear()
and skb_headlen() calls.

This patch was tested with pktgen in kernel tool in a script like this:
(pktgen_sample01_simple.sh is at [2]):

minSize=1
maxSize=1500

for i in `seq $minSize $maxSize` ; do
	copy="$(shuf -i 1-2000 -n 1)"
	./pktgen_sample01_simple.sh -i eth0 \
		-m <dst-mac-addr> -d <dst-ip-addr> -x -s $i -c $copy
done

minStep=1
maxStep=200
for i in `seq $minStep $maxStep` ; do
	copy="$(shuf -i 1-2000 -n 1)"
	size="$(shuf -i 1-1500 -n 1)"
	./pktgen_sample01_simple.sh -i eth0 \
		-m <dst-mac-addr> -d <dst-ip-addr> -x -s $size -c $copy
done

other queues are only data queues and does not need post_lock

If this flag is set, post_lock must be acquired before posting
a command to the queue.
If this flag is clear, post_lock is invalid for the queue.

When using an ip6tnl device in collect_md mode, the xmit methods ignore
the ipv6.src field present in skb_tunnel_info's key, both for route
calculation purposes (flowi6 construction) and for assigning the
packet's final ipv6h->saddr.

This makes it impossible specifying a desired ipv6 local address in the
encapsulating header (for example, when using tc action tunnel_key).

This is also not aligned with behavior of ipip (ipv4) in collect_md
mode, where the key->u.ipv4.src gets used.

Fix, by assigning fl6.saddr with given key->u.ipv6.src.
In case ipv6.src is not specified, ip6_tnl_xmit uses existing saddr
selection code.
