IPA v4.5 adds a few fields to the endpoint header and extended
header configuration registers that represent new high-order bits
for certain offsets and sizes.  Add code to incorporate these upper
bits into the registers for IPA v4.5.

This includes creating ipa_header_size_encoded(), which handles
encoding the metadata offset field for use in the ENDP_INIT_HDR
register in a way appropriate for the hardware version.  This and
ipa_metadata_offset_encoded() ensure the mask argument passed to
u32_encode_bits() is constant.

Update "ipa_reg.h" so that register definitions support IPA hardware
version 4.5, in addition to versions 3.5.1 through v4.2.  Most of
the register definitions are the same, but in some cases fields are
added, changed, or eliminated.

Updates for a few IPA v4.5 registers are more complex, and adding
those definition will be deferred to separate patches.  This patch
only updates the register offset and field definitions, and adds
informational comments.

The only code change avoids accessing the backward compatibility
register for IPA version 4.5 in ipa_hardware_config().  Other IPA
v4.5-specific code changes will come later.

Starting with IPA v4.2 there is a GSI channel option to use an
"escape buffer" instead of prefetch buffers.  This should be used
for all channels *except* the AP command TX channel.  The logic
that implements this has it backwards; fix this bug.

The 32-bit node number, aka node hash or node address, is calculated
based on the 128-bit node identity when it is not set explicitly by
the user. In future commits we will need to perform this hash operation
on peer nodes while feeling safe that we obtain the same result.

We do this by interpreting the initial hash as a network byte order
number. Whenever we need to use the number locally on a node
we must therefore translate it to host byte order to obtain an
architecure independent result.

Furthermore, given the context where we use this number, we must not
allow it to be zero unless the node identity also is zero. Hence, in
the rare cases when the xor-ed hash value may end up as zero we replace
it with a fix number, knowing that the code anyway is capable of
handling hash collisions.

mlxsw: Update adjacency index more efficiently

The device supports an operation that allows the driver to issue one
request to update the adjacency index for all the routes in a given
virtual router (VR) from old index and size to new ones. This is useful
in case the configuration of a certain nexthop group is updated and its
adjacency index changes.

Currently, the driver does not use this operation in an efficient
manner. It iterates over all the routes using the nexthop group and
issues an update request for the VR if it is not the same as the
previous VR.

Instead, this patch set tracks the VRs in which the nexthop group is
used and issues one request for each VR.

Example:

8k IPv6 routes were added in an alternating manner to two VRFs. All the
routes are using the same nexthop object ('nhid 1').

Before:

 Performance counter stats for 'ip nexthop replace id 1 via 2001:db8:1::2 dev swp3':

       0.000000000 seconds user
       0.666923000 seconds sys

Number of EMAD transactions corresponds to number of routes using the
nexthop group.

Patch #1 is a fix for a bug introduced in previous submission. Detected
by Coverity.

Patches #2 and #3 are preparations.

Patch #5 uses the membership tracking from the previous patch to issue
one update request per each VR.
