When a new ib device is up smc will send an add link invitation to the
peer if needed. This is currently done with rudimentary flow control.
Under high workload these add link invitations can disturb other llc
flows because they arrive unexpected. Fix this by integrating the
invitations into the normal llc event flow and handle them as a flow.
While at it, check for already assigned requests in the flow before
the new add link request is assigned.

Before an smc ib device is used the first time for an smc link it is
lazily initialized. When there are 2 active link groups and a new ib
device is brought online then it might happen that 2 link creations run
in parallel and enter smc_ib_setup_per_ibdev(). Both allocate new send
and receive completion queues on the device, but only one set of them
keeps assigned and the other leaks.
Fix that by protecting the setup and cleanup code using a mutex.

net: bcmgenet: fix WAKE_FILTER resume from deep sleep

The WAKE_FILTER logic can only wake the system from the standby
power state. However, some systems that include the GENET IP
support deeper power saving states and the driver should suspend
and resume correctly from those states as well.

This commit set squashes a few issues uncovered while testing
suspend and resume from these deep sleep states.

The Hardware Filter Block RAM may not be preserved when the GENET
block is reset during a deep sleep, so it is not sufficient to
only backup and restore the enables.

This commit clears out the HFB block and reprograms the rxnfc
rules when the system resumes from a suspended state. To support
this the bcmgenet_hfb_create_rxnfc_filter() function is modified
to access the register space directly so that it can't fail due
to memory allocation issues.

As "unsigned long" is 32-bit on sparc32, fix this by casting all tcflag_t
parameters to "unsigned int".
While at it, use "%u" to format unsigned numbers.

====================
bnxt_en: 3 bug fixes.

2 Fixes related to PHY/link settings.  The last one fixes the sizing of
the completion ring.

Please also queue for -stable.  Thanks.

The current completion ring sizing formula is wrong with TPA enabled.
The formula assumes that the number of TPA completions are bound by the
RX ring size, but that's not true.  TPA_START completions are immediately
recycled so they are not bound by the RX ring size.  We must add
bp->max_tpa to the worst case maximum RX and TPA completions.

The completion ring can overflow because of this mistake.  This will
cause hardware to disable the completion ring when this happens,
leading to RX and TX traffic to stall on that ring.  This issue is
generally exposed only when the RX ring size is set very small.

Fix the formula by adding bp->max_tpa to the number of RX completions
if TPA is enabled.

In a shared port PHY configuration, async event is received when any of the
port modifies the configuration. Ethtool link settings should be
initialised after updated PHY configuration from firmware.

The driver was modified to not rely on rtnl lock to protect link
settings about 2 years ago.  The pause setting was missed when
making that change.  Fix it by acquiring link_lock mutex before
calling bnxt_hwrm_set_pause().
