This patch series contains various fixes, additions and improvements to
mlx5 software steering.
Patch 1:
adds support for REMOVE_HEADER packet reformat - a new reformat type
that is supported starting with ConnectX-6 DX, and allows removing an
arbitrary size packet segment at a selected position.
Patches 2 and 3:
add support for VLAN pop on TX and VLAN push on RX flows.
Patch 4:
enables retransmission mechanism for the SW Steering RC QP.
Patch 5:
does some improvements to error flow in building STE array and adds
a more informative printout of an invalid actions sequence.
Patch 6:
improves error flow on SW Steering QP error.
Patch 7:
reduces the log level of a message that is printed when a table is
connected to a lower/same level destination table, as this case proves to
be not as rare as it was in the past.
Patch 8:
adds missing support for matching on IPv6 flow label for devices
older than ConnectX-6 DX.
Patch 9:
replaces uintN_t types with kernel-style types.
Patch 10:
allows for using the right API for updating flow tables - if it is
a FW-owned table, then FW API will be used.
Patch 11:
adds support for 'ignore_flow_level' on multi-destination flow
tables that are created by SW Steering.
Patch 12:
optimizes FDB RX steering rule by skipping matching on source port,
as the source port for all incoming packets equals to wire.
Patch 13:
is a small code refactoring - it merges several DR_STE_SIZE enums
into a single enum.
Patch 14:
does some additional refactoring and removes HW-specific STE type
from NIC domain.
Patch 15:
removes rehash ctrl struct from dr_htbl struct and saves some memory.
Patch 16:
does a more significant improvement in terms of memory consumption
and was able to save about 1.6 Gb for 8M rules.
Patch 17:
adds support for update FTE, which is needed for cases where there
are multiple rules with the same match.

mptcp: Optimize received options handling
These patches optimize received MPTCP option handling in terms of both
storage and fewer conditionals to evaluate in common cases, and also add
a couple of cleanup patches.
Patches 1 and 5 do some cleanup in checksum option parsing and
clarification of lock handling.
Patches 2 and 3 rearrange struct mptcp_options_received to shrink it
slightly and consolidate frequently used fields in the same cache line.
Patch 4 optimizes incoming MPTCP option parsing to skip many extra
comparisons in the common case where only a DSS option is present.

This change reorder the mptcp_options_received fields
to shrink the structure a bit and to ensure the most
frequently used fields are all in the first cacheline.
Sub-opt specific flags are moved out of the suboptions area,
and we must now explicitly set them when the relevant
suboption is parsed.
There is a notable exception: 'csum_reqd' is used by both DSS
and MPC suboptions, and keeping such field in the suboptions
flag area will simplfy the next patch.

The TCP_WINDOW_CLAMP socket option is defined in tcp(7) to "Bound the size
of the advertised window to this value." Window clamping is distributed
across two variables, window_clamp ("Maximal window to advertise" in
tcp.h) and rcv_ssthresh ("Current window clamp").
This patch updates the function where the window clamp is set to also
reduce the current window clamp, rcv_sshthresh, if needed. With this,
setting the TCP_WINDOW_CLAMP option has the documented effect of limiting
the window.

To track each STE of the rule a rule member was allocated, each
member would point to one STE. This means that we would allocate
40B (rule member) * number of STEs per rule.
To reduce this per rule allocation we use the STE tree pointers
for next_htbl and pointing STE to navigate the tree, this allows
us to keep only the pointer to the last STE of rule (always unique).
From the last rule STE we are able to traverse and rebuild all of
the STEs that construct the rule.
In our testing with 8M rules, each consisting of 7 STES, we were able
to reduce 1.6GB of memory.

side we want to clean up the API to stop reporting this.
Instead, check the IWL_RX_MPDU_STATUS_KEY_VALID bit that

that's set but we get invalid MIC/replay use the key ID
from the frame to look up the key and notify mac80211 of

When P2P roc is removed, the IWL_MVM_STATUS_NEED_FLUSH_P2P bit is set
to indicate to iwl_mvm_roc_done_wk() that the removed roc is a P2P
one, so it will flush the broadcast station and not the aux station.
However, since setting this bit and scheduling the worker is done
in roc ended flow as well as in case the roc is removed, there is
a race where the worker has already started running (but did not
test this bit yet) and then it is scheduled again. In this case,
the first run of the worker will clear this bit, and thus the second
run will find it already cleared and will try to flush and remove
the aux station by mistake.
Fix it by scheduling the worker only if this bit is not yet set. In
case this bit is already set, the worker is either running or
scheduled, so there is no need to re-schedule it.
