One PCIe function per network port (more precisely, per m-port group) is
 responsible for configuring the Match-Action Engine which performs
 switching and packet modification in the slice to support flower/OVS
 offload.  The GRP_MAE bit in the privilege mask indicates whether a
 given function has this capability.
At probe time, call MCDIs to read the calling function's privilege mask,
 and store the GRP_MAE bit in a new ef100_nic_data member.

Jann reported a race between munmap() and unmap_mapping_range(), where
unmap_mapping_range() will no-op once unmap_vmas() has unlinked the
VMA; however munmap() will not yet have invalidated the TLBs.

Therefore unmap_mapping_range() will complete while there are still
(stale) TLB entries for the specified range.

Mitigate this by force flushing TLBs for VM_PFNMAP ranges.

The previous patch removed the tlb_flush_end() implementation which
used tlb_flush_range(). This means:

 - csky did double invalidates, a range invalidate per vma and a full
   invalidate at the end

 - csky actually has range invalidates and as such the generic
   tlb_flush implementation is more efficient for it.

Scattered across the archs are 3 basic forms of tlb_{start,end}_vma().
Provide two new MMU_GATHER_knobs to enumerate them and remove the per
arch tlb_{start,end}_vma() implementations.

 - MMU_GATHER_NO_FLUSH_CACHE indicates the arch has flush_cache_range()
   but does *NOT* want to call it for each VMA.

 - MMU_GATHER_MERGE_VMAS indicates the arch wants to merge the
   invalidate across multiple VMAs if possible.

With these it is possible to capture the three forms:

  1) empty stubs;
     select MMU_GATHER_NO_FLUSH_CACHE and MMU_GATHER_MERGE_VMAS

  2) start: flush_cache_range(), end: empty;
     select MMU_GATHER_MERGE_VMAS

  3) start: flush_cache_range(), end: flush_tlb_range();
     default

Obviously, if the architecture does not have flush_cache_range() then
it also doesn't need to select MMU_GATHER_NO_FLUSH_CACHE.

DisplayLink ethernet devices require NTB buffers larger then 32kb
in order to run with highest performance.

This patch is changing upper limit of the rx and tx buffers.
Those buffers are initialized with CDC_NCM_NTB_DEF_SIZE_RX and
CDC_NCM_NTB_DEF_SIZE_TX which is 16kb so by default no device is
affected by increased limit.

Rx and tx buffer is increased under two conditions:
 - Device need to advertise that it supports higher buffer size in
   dwNtbMaxInMaxSize and dwNtbMaxOutMaxSize.
 - cdc_ncm/rx_max and cdc_ncm/tx_max driver parameters must be adjusted
   with udev rule or ethtool.

Summary of testing and performance results:
Tests were performed on following devices:
 - DisplayLink DL-3xxx family device
 - DisplayLink DL-6xxx family device
 - ASUS USB-C2500 2.5G USB3 ethernet adapter
 - Plugable USB3 1G USB3 ethernet adapter
 - EDIMAX EU-4307 USB-C ethernet adapter
 - Dell DBQBCBC064 USB-C ethernet adapter

Performance measurements were done with:
 - iperf3 between two linux boxes
 - http://openspeedtest.com/ instance running on local test machine

Insights from tests results:
 - All except one from third party usb adapters were not affected by
   increased buffer size to their advertised dwNtbOutMaxSize and
   dwNtbInMaxSize.
   Devices were generally reaching 912-940Mbps both download and upload.

   Only EDIMAX adapter experienced decreased download size from
   929Mbps to 827Mbps with iper3, with openspeedtest decrease was from
   968Mbps to 886Mbps.

 - DisplayLink DL-3xxx family devices experienced performance increase
   with iperf3 download from 300Mbps to 870Mbps and
   upload from 782Mbps to 844Mbps.
   With openspeedtest download increased from 556Mbps to 873Mbps
   and upload from 727Mbps to 973Mbps

 - DiplayLink DL-6xxx family devices are not affected by
   increased buffer size.

This series includes three changes to the transaction code.  The

transaction information structure, and reorders its initialization
a bit.  The third skips a function call when it is known not to be

pr_debug calls are no longer needed in this file.

Pablo suggested "a patch to remove these pr_debug calls". This patch has
some other beneficial collateral as it also silences multiple Clang
-Wformat warnings that were present in the pr_debug calls.

diff from v1 -> v2:
* converted if statement one-liner style
* x == NULL is now !x

With refcount_inc_not_zero, we'd also need a smp_rmb or similar,
followed by a test of the CONFIRMED bit.

However, the ct pointer is taken from skb->_nfct, its refcount must
not be 0 (else, we'd already have a use-after-free bug).

Use refcount_inc() instead to clarify the ct refcount is expected to
be at least 1.

Use bitmap_zalloc()/bitmap_free() instead of hand-writing them.

It is less verbose and it improves the semantic.
