In the current driver implementation two types of receive queue
tables (RQTs) are in use - direct and indirect.
Change the driver to mark each new created RQT (direct or indirect)
as "enabled". This behaviour is needed for introducing new mlx5e
instances which serve to represent SRIOV VFs.
The VF representors will have only one type of RQTs (direct).
An "enabled" flag is added to each RQT to allow better handling
and code sharing between the representors and the nic netdevices.

The current refresh tirs self loopback mechanism, refreshes all the tirs
belonging to the same mlx5e instance to prevent self loopback by packets
sent over any ring of that instance. This mechanism relies on all the
tirs/tises of an instance to be created with the same transport domain
number (tdn).
Change the driver to refresh all the tirs created under the same tdn
regardless of which mlx5e netdev instance they belong to.
This behaviour is needed for introducing new mlx5e instances which serve
to represent SRIOV VFs. The representors and the PF share vport used for
E-Switch management, and we want to avoid NIC level HW loopback between
them, e.g when sending broadcast packets. To achieve that, both the
representors and the PF NIC will share the tdn.

Unlike the legacy mode, here, forwarding rules are not learned by the
driver per events on macs set by VFs/VMs into their vports, but rather
should be programmed by higher-level SW entities.
Saying that, still, in the offloads mode (SRIOV_OFFLOADS), two flow
groups are created by the driver for management (slow path) purposes:
The first group will be used for sending packets over e-switch vports
from the host OS where the e-switch management code runs, to be
received by VFs.
The second group will be used by a miss rule which forwards packets toward
the e-switch manager. Further logic will trap these packets such that
the receiving net-device as seen by the networking stack is the representor
of the vport that sent the packet over the e-switch data-path.

When handling IP fragmented packets with csum in their
transport header, the csum isn't changed as part of the
fragmentation. As a result, the packet containing the
transport headers would have the correct csum of the original
packet, but one that mismatches the actual packet that
passes on the wire. As a result, on receive path HW would
give an indication that the packet has incorrect csum,
which would cause qede to discard the incoming packet.
Since HW also delivers a notification of IP fragments,
change driver behavior to pass such incoming packets
to stack and let it make the decision whether it needs

Intel Wired LAN Driver Updates 2016-06-29
This series contains updates and fixes to e1000e, igb, ixgbe and fm10k. A
true smorgasbord of changes.
Jake cleans up some obscurity by not using the BIT() macro on bitshift
operation and also fixed the calculated index when looping through the
indir array. Fixes the issue with igb's workqueue item for overflow
check from causing a surprise remove event. The ptp_flags variable is
added to simplify the work of writing several complex MAC type checks
in the PTP code while fixing the workqueue.
Alex Duyck fixes the receive buffers alignment which should not be L1
cache aligned, but to 512 bytes instead.
Denys Vlasenko prevents a division by zero which was reported under
VMWare for e1000e.
Amritha fixes an issue where filters in a child hash table must be
cleared from the hardware before delete the filter links in ixgbe.
Bhaktipriya Shridhar simply replaces the deprecated create_workqueue()
with alloc_workqueue() for fm10k.
Tony corrects ixgbe ethtool reporting to show x550 supports hardware
timestamping of all packets.
Emil fixes an issue where MAC-VLANs on the VF fail to pass traffic due
to spoofed packets.
Andrew Lunn increases performance on some systems where syncing a buffer
for DMA is expensive. So rather than sync the whole 2K receive buffer,
only synchronize the length of the frame.

alloc_workqueue replaces deprecated create_workqueue().
A dedicated workqueue has been used since the workitem (viz
fm10k_service_task, which manages and runs other subtasks) is involved in
normal device operation and requires forward progress under memory
pressure.
create_workqueue has been replaced with alloc_workqueue with max_active
as 0 since there is no need for throttling the number of active work
items.
Since network devices may be used in memory reclaim path,
WQ_MEM_RECLAIM has been set to guarantee forward progress.
flush_workqueue is unnecessary since destroy_workqueue() itself calls
drain_workqueue() which flushes repeatedly till the workqueue
becomes empty. Hence the call to flush_workqueue() has been dropped.
