mptcp: Add full mesh path manager option

The path manager in MPTCP controls the creation of additional subflows
after the initial connection is created. As each peer advertises
available endpoints with the ADD_ADDR MPTCP option, the recipient of
those advertisements must decide which subflows to create from the known
local and remote interfaces that are available for use by MPTCP.

The existing in-kernel path manager will create one additional subflow
when an ADD_ADDR is received, or a local address is newly configured for
MPTCP use. The maximum number of subflows has a configurable limit.

This patch set adds a MPTCP_PM_ADDR_FLAG_FULLMESH flag to the MPTCP
netlink API that enables subflows to be created more aggressively. When
an ADD_ADDR is received from a peer, new subflows are created between
that address/port and all local addresses configured for MPTCP.
Similarly, when a new local address is newly configured for use by
MPTCP, new subflows are created between that local address and all known
remote addresses for that MPTCP connection. The configurable limit on
the number of subflows still applies. If the new flag is not used the
path manager behavior is unchanged.

Patch 1 adds a helper function and refactors another function to prepare
for the rest of the patch series.

Patches 2 and 3 add two mesh connection capabilities: initiating
subflows based on added local addresses, or reacting to incoming
advertisements.

Patches 4-6 add full mesh cases to the self tests.

octeontx2: Rework MCAM flows management for VFs

From Octeontx2 hardware point of view there is no
difference between PFs and VFs. Hence with refactoring
in driver the packet classification features or offloads
can be supported by VFs also. This patchset unifies the
mcam flows management so that VFs can also support
ntuple filters. Since there are MCAM allocations by
all PFs and VFs in the system it is required to have
the ability to modify number of mcam rules count
for a PF/VF in runtime. This is achieved by using devlink.
Below is the summary of patches:

Patch 1,2,3 are trivial patches which helps in debugging
in case of errors by using custom error codes and
displaying proper error messages.

Patches 4,5 brings rx-all and ntuple support
for CGX mapped VFs and LBK VFs.

Patches 6,7,8 brings devlink support to
PF netdev driver so that mcam entries count
can be changed at runtime.
To change mcam rule count at runtime where multiple rule
allocations are done sorting is required.
Also both ntuple and TC rules needs to be unified.

Patch 9 is related to AF NPC where a PF
allocated entries are allocated at bottom(low priority).

On CN10K there is slight change in reading
NPC counters which is handled by patch 10.

Patch 11 is to allow packets from CPT for
NPC parsing on CN10K.

If the mcam entry allocation request is from PF
and NOT a priority allocation request then allocate
low priority entries so that PF entries always have
lower priority than its VFs. This is required so
that entries with (base) MCAM match criteria have lower
priority compared to entries with (base + additional)
match criteria. This patch considers only best case
scenario where PF entries are allocated from low
priority zone if low priority zone has free space.
There are worst case scenarios like:
1. VFs allocating hundreds of MCAM entries leading to VFs
using all mid priority zone and low priority zone entries
hence no entries free from low priority zone for PF.
2. All the PFs and VFs in the system allocating and freeing
entries causing fragmentation in MCAM space and all the
entries requested by PF could not fit in low priority
zone for allocation.
This patch do not handle worst case scenarios.

Since the original TFO server code was implemented in commit
168a8f58 ("tcp: TCP Fast Open Server -
main code path") the TFO server code has supported the sysctl bit flag
TFO_SERVER_COOKIE_NOT_REQD. Currently, when the TFO_SERVER_ENABLE and
TFO_SERVER_COOKIE_NOT_REQD sysctl bit flags are set, a server connection
will accept a SYN with N bytes of data (N > 0) that has no TFO cookie,
create a new fast open connection, process the incoming data in the SYN,
and make the connection ready for accepting. After accepting, the
connection is ready for read()/recvmsg() to read the N bytes of data in
the SYN, ready for write()/sendmsg() calls and data transmissions to
transmit data.

This commit changes an edge case in this feature by changing this
behavior to apply to (N >= 0) bytes of data in the SYN rather than only
(N > 0) bytes of data in the SYN. Now, a server will accept a data-less
SYN without a TFO cookie if TFO_SERVER_COOKIE_NOT_REQD is set.

Caveat! While this enables a new kind of TFO (data-less empty-cookie
SYN), some firewall rules setup may not work if they assume such packets
are not legit TFOs and will filter them.
