The standard behaviour for binary API is that zeroed arguments are
treated as if the default values were set. This way the configurator
does not need to know what default values are.
This, however, wasn't the case for rx_queues and tx_queues in
memif_create binary API message.

interface
Multiple subsequent calls to vnet_feature_enable_disable() to enable the feature
cause the feature to be inserted into the processing graph multiple times in a row.
This might be argued to be a bug in that function, but enabling already enabled feature
is suboptimal anyway, so avoid that. The existing tests already catch this issue whenever
the ASSERT() part of this patch was added.

If interface is down and queues are not configured then we are not able
to change rx-mode. This change introducess default mode which is stored
per interface and applied if driver wants.

It is useful to have the CLI to clear the existing sessions.
There was a work-in-progress CLI but it did not work properly.
Fix it and split into a separate "clear acl-plugin sessions",
and add a unit test into the extended connection-oriented tests.

n_input == 0
The logic to print the line " output " is wrong for the case of n_input == 0,
and the applied ACLs are printed as if they were applied on input.
One may still figure out the truth by looking at the n_input value above,
but it is confusing.

Add a bihash-based ACL lookup mechanism and make it a new default.
This changes the time required to lookup a 5-tuple match
from O(total_N_entries) to O(total_N_mask_types), where
"mask type" is an overall mask on the 5-tuple required
to represent an ACE.
For testing/comparison there is a temporary debug CLI
"set acl-plugin use-hash-acl-matching {0|1}", which,
when set to 0, makes the plugin use the "old" linear lookup,
and when set to 1, makes it use the hash-based lookup.
Based on the discussions on vpp-dev mailing list,
prevent assigning the ACL index to an interface,
when the ACL with that index is not defined,
also prevent deleting an ACL if that ACL is applied.
Also, for the easier debugging of the state, there are
new debug CLI commands to see the ACL plugin state at
several layers:
"show acl-plugin acl [index N]" - show a high-level
ACL representation, used for the linear lookup and
as a base for building the hashtable-based lookup.
Also shows if a given ACL is applied somewhere.
"show acl-plugin interface [sw_if_index N]" - show
which interfaces have which ACL(s) applied.
"show acl-plugin tables" - a lower-level debug command
used to see the state of all of the related data structures
at once. There are specifiers possible, which make
for a more focused and maybe augmented output:
"show acl-plugin tables acl [index N]"
show the "bitmask-ready" representations of the ACLs,
we well as the mask types and their associated indices.
"show acl-plutin tables mask"
show the derived mask types and their indices only.
"show acl-plugin tables applied [sw_if_index N]"
show the table of all of the ACEs applied for a given
sw_if_index or all interfaces.
"show acl-plugin tables hash [verbose N]"
show the 48x8 bihash used for the ACL lookup.

Current memif interface supports frame size up to 2048. This patch is to
enhance memif to support jumbo frames.
On tx (writing buffers to the ring), keep reading the next buffer in vlib
when the flag VLIB_BUFFER_NEXT_PRESENT and merge it to the same ring entry.
Use descriptor chaining if the buffer is not big enough.
On rx (reading buffers from the ring), if the packet is greater than 2048,
create multiple vlib buffers, chained with the VLIB_BUFFER_NEXT_PRESENT.
Testing:
Because the ping command provided by VPP does not support jumbo frames,
I have to use linux ping. Here is the set up that I use for testing.
VM1 --- vhost ---- VPP1 --- memif --- VPP2 --- vhost --- VM2
Create vhost-user interfaces between VM1 and VPP1 and between VPP2 and VM2
VM configuration:
Set the interface mtu on the VM, e.g 9216 to support jumbo frames.
create static route and static arp on VM1 to VM2 and vice versa.
Use iperf3 or ping -s 8000 from VM1 to VM2 or vice versa.
Sample run
sluong@ubuntu:~$ ping 131.1.1.1 -c1 -s 8000
ping 131.1.1.1 -c1 -s 8000

A bihash-per-interface is convenient, but turns out tricky difficult from
the maintenance standpoint with the large number of interfaces.
This patch makes the sessions reside in a single hash table for all the interfaces,
adding the lower 16 bit of sw_if_index as part of the key into the previously
unused space.
There is a tradeoff, that a session with an identical 5-tuple and the same
sw_if_index modulo 65536 will match on either of the interfaces.
The probability of that is deemed sufficiently small to not worry about it.
In case it still happens before the heat death of the universe,
there is a clib_warning and the colliding packet will be dropped,
at which point we will need to bump the hash key size by another u64,
but rather not pay the cost of doing that right now.

The previous iteration of the code used the L2 classifier tables for session storage,
as a result, the table allocations were pretty big. The new ACL plugin
datapath uses the tables just as a redirection mechanism, without adding any
entries. Thus, the tables can be much smaller.

crc_u32 was not defined for non x86_64 with SSE4.2 processors.
Calls to "crc_u32" are removed and replaced by either a call to
clib_crc32c or a call to clib_xxhash, as the result is not used
as a check value but as a hash.

Attempting to supply within a VAT CLI to add the ACLs a rule count
override with no rules to add would result in null pointer dereference
as we attempt to copy those rules to the message.
Add the check to avoid copy if the source pointer is null
(i.e. if there are no rules to copy from).

I am able to reproduce the problem consistently with the below procedure.
1. Create 3 memif interfaces between slave and master instances.
2. Type 'quit' on the slave. Neither crashes the first time.
3. Bring back the slave. Type 'quit' on the master. Neither crashes.
4. Bring back the master. Type 'quit' on the slave. The master crashes.
There are two places the interrupt line is disconnected and the unix file is
removed via the call unix_file_del ()
1. memif_int_fd_read_ready ()
2. memif_disconnect () which is called via multiple places in memif.
When the crash happens, the unix file was removed from memif_disconnect ()
via memif_conn_fd_read_ready () with size of the message == 0 in recvmsg ().
It is noted when the unix file was removed from memif_int_fd_read_ready (),
it never crashes. It is a race condition. However, if I follow the
aformentioned procedure, the crash always happens.
The reason the crash happens when memif_disconnect () removes the unix file
is because there may still be pending input in linux_epoll_input (). When
linux_epoll_input () tries to access the unix file via the line 200
unix_file_t *f = pool_elt_at_index (um->file_pool, i);
it crashes.
We could add code in linux_epoll_input () to avoid the crash if the index
for the particular file_pool is already free. Or we could fix memif to not
remove the unix file in memif_conn_fd_read_ready () when recvmsg () got 0
byte and just postpone the unix file deletion in memif_int_fd_read_ready ()
later after linux_epoll_input () got a chance to run to empty the input
stream.
I choose to fix the problem in the latter approach. I split the function
memif_disconnect () into two parts. For the code path which
memif_conn_fd_read_ready () calls memif_disconnect (), it does not remove the
unix file. All other calls to memif_disconnect () will continue to do what
it uses to do to avoid regression.
Please let me know if I should fix the problem other way.
