Trivial fix to typos in netdev_err error messages. I should have spotted
this in a previous round of spelling mistake checks on this driver but
this one slipped through.

All uses of refresh_scan() have a constant 1 as the second argument.
Remove it and neaten the function declaration.
Miscellanea:
o Remove overly deep indentation by using continue;
o Remove unnecessary test of the address of a static array as it's
always non-zero
o Rename and use proper type for the first void * argument as it's
always the struct wilc_priv *
o Move variables into loop where used

The ccree driver had its own FIPS support, complete with
a test harness comparable to crypto testmgr and an
implementation which disables crypto functionality on
FIPS test error detection, either in Linux or from TEE.
This patch removes the duplication, while reimplementing
the handling of TEE reported FIPS errors according to the
kernel policy of inducing a panic in such an event.

====================
bcmgenet: Fragmented SKB corrections
Two issues were observed in a review of the bcmgenet driver support for
fragmented SKBs which are addressed by this patch set.
The first addresses a problem that could occur if the driver is not able
to DMA map a fragment of the SKB. This would be a highly unusual event
but it would leave the hardware descriptors in an invalid state which
should be prevented.
The second is a hazard that could occur if the driver is able to reclaim
the first control block of a fragmented SKB before all of its fragments
have completed processing by the hardware. In this case the SKB could
be freed leading to reuse of memory that is still in use by hardware.
====================

Since the skb is attached to the first control block of a fragmented
skb it is possible that the skb could be freed when reclaiming that
control block before all fragments of the skb have been consumed by
the hardware and unmapped.
This commit introduces first_cb and last_cb pointers to the skb
control block used by the driver to keep track of which transmit
control blocks within a transmit ring are the first and last ones
associated with the skb.
It then splits the bcmgenet_free_cb() function into transmit
(bcmgenet_free_tx_cb) and receive (bcmgenet_free_rx_cb) versions
that can handle the unmapping of dma mapped memory and cleaning up
the corresponding control block structure so that the skb is only
freed after the last associated transmit control block is reclaimed.

In case we fail to map a single fragment, we would be leaving the
transmit ring populated with stale entries.
This commit introduces the helper function bcmgenet_put_txcb()
which takes care of rewinding the per-ring write pointer back to
where we left.
It also consolidates the functionality of bcmgenet_xmit_single()
and bcmgenet_xmit_frag() into the bcmgenet_xmit() function to
make the unmapping of control blocks cleaner.

Fixes the following behavior: for connections that had no RTT sample
at the time of initializing congestion control, BBR was initializing
the pacing rate to a high nominal rate (based an a guess of RTT=1ms,
in case this is LAN traffic). Then BBR never adjusted the pacing rate
downward upon obtaining an actual RTT sample, if the connection never
filled the pipe (e.g. all sends were small app-limited writes()).
This fix adjusts the pacing rate upon obtaining the first RTT sample.

Fix a corner case noticed by Eric Dumazet, where BBR's setting
sk->sk_pacing_rate to 0 during initialization could theoretically
cause packets in the sending host to hang if there were packets "in
flight" in the pacing infrastructure at the time the BBR congestion
control state is initialized. This could occur if the pacing
infrastructure happened to race with bbr_init() in a way such that the
pacer read the 0 rather than the immediately following non-zero pacing
rate.

In bbr_set_pacing_rate(), which decides whether to cut the pacing
rate, there was some code that considered exiting STARTUP to be
equivalent to the notion of filling the pipe (i.e.,
bbr_full_bw_reached()). Specifically, as the code was structured,
exiting STARTUP and going into PROBE_RTT could cause us to cut the
pacing rate down to something silly and low, based on whatever
bandwidth samples we've had so far, when it's possible that all of
them have been small app-limited bandwidth samples that are not
representative of the bandwidth available in the path. (The code was
correct at the time it was written, but the state machine changed
without this spot being adjusted correspondingly.)

When there is an established connection in direction A->B, it is
possible to receive a packet on port B which then executes
ct(commit,force) without first performing ct() - ie, a lookup.
In this case, we would expect that this packet can delete the existing
entry so that we can commit a connection with direction B->A. However,
currently we only perform a check in skb_nfct_cached() for whether
OVS_CS_F_TRACKED is set and OVS_CS_F_INVALID is not set, ie that a
lookup previously occurred. In the above scenario, a lookup has not
occurred but we should still be able to statelessly look up the
existing entry and potentially delete the entry if it is in the
opposite direction.
This patch extends the check to also hint that if the action has the
force flag set, then we will lookup the existing entry so that the
force check at the end of skb_nfct_cached has the ability to delete
the connection.

Some time ago David Woodhouse reported skb_under_panic
when we try to push ethernet header to fragmented ipv6 skbs.
It was fixed for ipv6 by Florian Westphal in
commit 1d325d217c7f ("ipv6: ip6_fragment: fix headroom tests and skb leak")
However similar problem still exist in ipv4.
It does not trigger skb_under_panic due paranoid check
in ip_finish_output2, however according to Alexey Kuznetsov
current state is abnormal and ip_fragment should be fixed too.

The function __mlx4_zone_remove_one_entry always returns zero. So
it is not necessary to check it.

Computing the alignment manually for going from priv to pub is probably
not such a good idea, and in general the assumption that going from priv
to pub is possible trivially could change, so rather than relying on
that, we change things to just store a pointer to pub. This was sugested
by DaveM in [1].

Specifying IDM register space in DT is not mendatory for SoCs
where firmware takes care of IDM operations. This patch updates
BGMAC driver's DT binding documentation indicating the same.

IDM operations are usually one time ops and should be done in
firmware itself. Driver is not supposed to touch IDM registers.
However, for some SoCs', driver is performing IDM read/writes.
So this patch masks IDM operations in case firmware is taking
care of IDM operations.
