Pull networking fixes from David Miller:
 "A decent batch of fixes here. I'd say about half are for problems that
  have existed for a while, and half are for new regressions added in
  the 4.20 merge window.

  15) Fix SKB use after passing to netif_receive_skb(), from Prashant
      Bhole.

      Falcon.

  19) Several small TCP fixes (off-by-one on window probe abort, NULL
      deref in tail loss probe, SNMP mis-estimations) from Yuchung
      Cheng"

net/sched: cls_flower: Reject duplicated rules also under skip_sw

2018-12-09T19:55:08+00:00

Currently, duplicated rules are rejected only for skip_hw or "none",
hence allowing users to push duplicates into HW for no reason.

Use the flower tables to protect for that.

Michael Chan says:

====================
bnxt_en: Bug fixes.

The first patch fixes a regression on CoS queue setup, introduced
recently by the 57500 new chip support patches.  The rest are
fixes related to ring and resource accounting on the new 57500 chips.
====================

bnxt_en: Fix _bnxt_get_max_rings() for 57500 chips.

2018-12-09T19:46:58+00:00

The CP rings are accounted differently on the new 57500 chips.  There
must be enough CP rings for the sum of RX and TX rings on the new
chips.  The current logic may be over-estimating the RX and TX rings.

The output parameter max_cp should be the maximum NQs capped by
MSIX vectors available for networking in the context of 57500 chips.
The existing code which uses CMPL rings capped by the MSIX vectors
works most of the time but is not always correct.

bnxt_en: Fix NQ/CP rings accounting on the new 57500 chips.

2018-12-09T19:46:58+00:00

The new 57500 chips have introduced the NQ structure in addition to
the existing CP rings in all chips.  We need to introduce a new
bnxt_nq_rings_in_use().  On legacy chips, the 2 functions are the
same and one will just call the other.  On the new chips, they
refer to the 2 separate ring structures.  The new function is now
called to determine the resource (NQ or CP rings) associated with
MSIX that are in use.

On 57500 chips, the RDMA driver does not use the CP rings so
we don't need to do the subtraction adjustment.

bnxt_en: Keep track of reserved IRQs.

2018-12-09T19:46:58+00:00

The new 57500 chips use 1 NQ per MSIX vector, whereas legacy chips use
1 CP ring per MSIX vector.  To better unify this, add a resv_irqs
field to struct bnxt_hw_resc.  On legacy chips, we initialize resv_irqs
with resv_cp_rings.  On new chips, we initialize it with the allocated
MSIX resources.
