This patch adds the flow support to VPP avf_plugin.
Currently only IP4-N-TUPLE and GTPU flow are supported as
a reference. More flows will be added later.

Type: refactor
This patch refactors the offload flags in vlib_buffer_t.
There are two main reasons behind this refactoring.
First, offload flags are insufficient to represent outer
and inner headers offloads. Second, room for these flags
in first cacheline of vlib_buffer_t is also limited.
This patch introduces a generic offload flag in first
cacheline. And detailed offload flags in 2nd cacheline
of the structure for performance optimization.

Use vlib_buffer_t::current_data instead of
vnet_buffer_opaque_t::l2_hdr_offset to compute l2_len for checksum
offload (l2_hdr_offset might be invalid if packet originates from an L3
interface)

Initializing struct avf_ip6_psh by {0} using gcc with O2 optimize option
will trigger the -Werror=maybe-uninitialized compiling warning on Arm
because gcc compiler will think some members of the struct avf_ip6_psh
may not be initialized, which probably is a false positive in this case.
The compiling error log is shown as below. Avoid this compiling warning
by explicitly declaring the IPv6 src and dst ip in avf_ip6_psh as
ip6_address_t.

Entering duplicate pci address when creating an avf interface causes
crash in register_node
(gdb) f 4
145 error_exit (1);
(gdb) up
354 clib_error ("more than one node named `%v'", n->name);
(gdb) p n
$1 = (vlib_node_t *) 0x7fffbbe55de4
(gdb) p n->name
$2 = (u8 *) 0x7fffbc410b10 "avf-0/4/a/0-tx"
(gdb)
The fix is to loop through the pci addresses in the avf interface pool
and to reject the duplicate.

It may happen that process node is suspended while it waits for response
from adminq and during that time CLI or API process can call
avf_delete_if. When avf process node resumes, it may happen that device
is not there anymeore.
This patch delegates interface deletion to process node, so CLI/API
process just sends signal instead of deleting device instance itself.

Fix and optimize DMAC check in ethernet-input node to utilize NIC or
driver which support L3 DMAC-filtering mode so that DMAC check can be
bypassed safely for interfaces/sub-interfaces in L3 mode.
Checking of interface in L3-DMAC-filtering state to avoid DMAC check
require the following:
a) Fix interface driver init sequence for devices which supports L3
DMAC-filtering to indicate its capability and initialize interface
to L3 DMAC-filtering state.
b) Fix ethernet_set_flags() function and its associated callback
flags_change() functions registered by various drivers in interface
infra to provide proper L3 DMAC filtering status.
Maintain interface/sub-interface L3 config count so DMAC checks can be
bypassed if L3 forwarding is not setup on any main/sub-interfaces.

For chain buffer, need to traverse b->next_buffer to transmit all buffers
in the chain. Only set EOP at the last descriptor in the chain to signal
this is a chain descriptor.
Introduce slow path to handle ring wrap. This is needed because chain
buffer may consist of multiple pieces and it may span from near the end of
the ring to the beginning of the ring.

Multiple API message handlers call vnet_get_sup_hw_interface(...)
without checking the inbound sw_if_index. This can cause a
pool_elt_at_index ASSERT in a debug image, and major disorder in a
production image.
Given that a number of places are coded as follows, add an
"api_visible_or_null" variant of vnet_get_sup_hw_interface, which
returns NULL given an invalid sw_if_index, or a hidden sw interface:
- hw = vnet_get_sup_hw_interface (vnm, sw_if_index);
+ hw = vnet_get_sup_hw_interface_api_visible_or_null (vnm, sw_if_index);
if (hw == NULL || memif_device_class.index != hw->dev_class_index)
return clib_error_return (0, "not a memif interface");
Rename two existing xxx_safe functions -> xxx_or_null to make it
obvious what they return.

The fast path almost always has to deal with the real
pointers. Deriving the frame pointer from a frame_index requires a
load of the 32bit frame_index from memory, another 64bit load of the
heap base pointer and some calculations.
Lets store the full pointer instead and do a single 64bit load only.
This helps avoiding problems when the heap is grown and frames are
allocated below vm->heap_aligned_base.

If the corresponding vpp plugin is absent, return a non-zero
clib_error_t * from vat_plugin_register ("xxx plugin not loaded"). The
vat plugin calls dlclose on the vat plugin, and it disappears.
Depending on the plugin configuration, this can reduce the vpp virtual
size by several gigabytes.
Added a VAT_PLUGIN(<plugin-name>) macro to vat_helper_macros, clean up
boilerplate vat_plugin_register() implementations. Fixed a number of
non-standard vat_plugin_register methods.
