This patch removes the read/write operations to the CIAA/D registers
and makes use of standard kernel functions for accessing the PCI config
space.

In addition it moves ixgbevf_check_for_bad_vf() into the watchdog subtask
which reduces the frequency of the checks.

This patch cleans up the page reuse code getting it into a state where all
the workarounds needed are in place as well as cleaning up a few minor
oversights such as using __free_pages instead of put_page to drop a locally
allocated page.

It also cleans up how we clear the descriptor status bits.  Previously they
were zeroed as a part of clearing the hdr_addr.  However the hdr_addr is a
64 bit field and 64 bit writes can be a bit more expensive on on 32 bit
systems.  Since we are no longer using the header split feature the upper
32 bits of the address no longer need to be cleared.  As a result we can
just clear the status bits and leave the length and VLAN fields as-is which
should provide more information in debugging.

Add L2 bridge offloading support to rocker driver.  Here, the Linux bridge
driver is used to collect swdev ports into a tagged (or untagged) VLAN
bridge.  The switchdev will offload from the bridge driver the following L2
bridging functions:

 - Learning of neighbor MAC addresses on VLAN X  Learned mac/vlan is
installed in bridge FDB.  (And removed when device unlearns mac/vlan).
Learning must be turned off on each bridge port to disable the feature in
the bridge driver.

- Flooding of multicast/broadcast and unknown unicast pkts to (STP)
active ports in bridge.  The bridge driver is unaware of the flooding happening
at the device level.  Flooding must be turned off on each bridge port to
disable the feature on the bridge driver.

- STP port state is pushed down to driver/device.  The bridge still processes
STP BDPUs and maintains port STP state (for all VLANs in bridge), but
the driver/device must be notified of port STP state change to program
the device.

Multiple (VLAN) bridges are supported.  The device (implemented per
the OF-DPA spec) must use a portion of the VLAN namespace for
internal VLANs.  Right now, the upper 255 VLANs (0xf00 to 0xffe) are
used as internal VLAN IDs for untagged traffic and are not available
as port VLANs.

The driver uses the following interfaces:

1. To track VLAN add/del on ports in bridge:

.ndo_vlan_rx_add_vid
.ndo_vlan_rx_kill_vid

2. To track port add/del membership in bridge:

NETDEV_CHANGEUPPER netdevice notifier

3. To catch static FDB entries installed on bridge/vlan by user using netlink:

.ndo_fdb_add
.ndo_fdb_del

4. To be notified on port STP state change:

.ndo_switch_port_stp_update

5. To notify bridge driver on learned/forgotten mac/vlans on bridge port:

br_fdb_external_learn_add
br_fdb_external_learn_del

The rocker driver maintains 4 hash tables: flows, groups, FDB, and VLANs.

Flow and group tables track the entries installed to OF-DPA tables,
per the OF-DPA spec.  See OF-DPA spec for full description of fields
in each flow and group table.  New table entries are pushed to the
device with ADD cmd.  Updated entries are pushed to the device with
MOD cmd.  For flow table entries, a crc32 key is made from fields of
the particular field.  For group table entries, the group_id is used
as the key.

The FDB table tracks fdb entries learned by the device or manually
pushed to the bridge by the user.  A crc32 key is made from the
port/mac/vlan tuple for the fdb entry.

The VLAN table tracks the ifindex-to-internal-vlan mapping for
untagged pkts.  On ingress, an untagged pkt is inserted with an
internal VLAN ID based on the input port's current internal VLAN ID.
The input port's internal VLAN will either be referenced by the port's
ifindex, if not bridged, or the containing bridge's ifindex, if
bridged.  Since the ifindex space isn't within a fixed range, uses a
hash table (with ifindex as key) to track internal VLAN ID for a given
ifindex.  The internal VLAN ID range is fixed and currently uses the
upper 255 VLAN IDs, starting at 0xf00.

Some VF drivers use the upper byte of "param1" (the qp count field)
in mlx4_qp_reserve_range() to pass flags which are used to optimize
the range allocation.

Under the current code, if any of these flags are set, the 32-bit
count field yields a count greater than 2^24, which is out of range,
and this VF fails.

As these flags represent a "best-effort" allocation hint anyway, they may
safely be ignored. Therefore, the PF driver may simply mask out the bits.
