The PPv2 classifier allows to perform multiple lookups on the same
engine when classifying a packet. These lookups can match similar parts
of a packet header, but perform different actions upon matching. To
differentiate these types of lookups, it's possible to specify a Lookup
Type in the flow table entries, which will be part of the key for the
lookup engines.
This commit introduces the use of Lookup Types for C2 matches. Since for
now we only perform C2 lookups to enable RSS, we only need one Lookup
Type.

The Classifier flow table has 512 entries, that contains lookups
commands executed consecutively for every flow. Since we have 21
different flows, we have to carefully manage the flow table use.
As of today, the start index of a lookup sequence is computed
directly based in the flow->id. There are 8 reserved flow ids, from
0-7, which don't have any corresponding sequence in the flow table. We
can therefore ignore them when computing the index, and make so that the
first non-reserved flow point to the very beginning of the flow table.

Some enums in ice_tx_desc_cmd_bits have a trailing /* 2 BITS */ comment,
but the value has just one bit set (ex. ICE_TX_DESC_CMD_L4T_EOFT_SCTP

Currently the ice_q_vector structure and ice_ring_container structure
are taking up more space than necessary due to cache alignment holes
and unnecessary variables respectively. This is not helping the
driver's performance. The following fixes were done to improve cache
alignment, reduce wasted space, and increase performance.
1. Remove the ice_latency_range enum as it is unused.
2. Remove the latency_range variable in the ice_ring_container structure.
3. Change the size of the itr_idx in the ice_ring_container structure
from an int to an u16. This reduced the size of ice_ring_container
structure to 32 Bytes so it has no holes or padding.
4. Re-arrange the ice_q_vector structure using pahole to align
members as best as possible in regards to 64 Byte cache line size.

It was caused by the netns freed without deleting the discoverer timer,
while later on the netns would be accessed in the timer handler.
The timer should have been deleted by tipc_net_stop() when cleaning up a
netns. However, tipc has been able to enable a bearer and start d->timer
without the local node_addr set since Commit 52dfae5c85 ("tipc: obtain
node identity from interface by default"), which caused the timer not to
be deleted in tipc_net_stop() then.
So fix it in tipc_net_stop() by changing to check local node_id instead
of local node_addr, as Jon suggested.
While at it, remove the calling of tipc_nametbl_withdraw() there, since
tipc_nametbl_stop() will take of the nametbl's freeing after.

100GbE Intel Wired LAN Driver Updates 2019-03-25
This series contains updates to the ice driver only.
Victor updates the ice driver to be able to update the VSI queue
configuration dynamically, by providing the ability to increase or
decrease the VSI's number of queues.
Michal fixes an issue when the VM starts or the VF driver is reloaded,
the VLAN switch rule was lost (i.e. not added), so ensure it gets added
in these cases.
Brett updates the driver to support link events over the admin receive
queue, instead of polling link events.
Maciej refactors the code a bit to introduce a new function to fetch the
receiver buffer and do the DMA synchronization to reduce the code
duplication. Also added ice_can_reuse_rx_page() to verify whether the
page can be reused so that in the future, we can use this check
elsewhere in the driver. Additional driver optimizations so that we can
drop the ice_pull_tail() altogether. Added support for bulk updates of
refcount instead of doing it one by one. Refactored the page counting
and buffer recycling so that we can use this code to clean up receive
buffers when there is no skb allocated, like XDP. Added
DMA_ATTR_WEAK_ORDERING and DMA_ATTR_SKIP_CPU_SYNC attributes to the DMA
API during the mapping operations on the receive side, so that nonx86
platforms will be able to sync with what is being used (2k buffers)
instead of the entire page.
Dave fixes the driver to perform the most intrusive of the resets
requested and clear the other request bits so that we do not end up with
repeated reset, after reset.
Bruce adds a iterator macro to clean up several for() loops.
Chinh modifies the packet flags to be more generic so that they can be
used for both receive and transmit.
