We shouldn't trigger another EMPR when we receive an EMPR event.
This patch handles EMPR event reception with a different state
so that we can do the right thing for NVM.

Until the time a more robust versioning scheme is needed/implemented all
established virtual channel opcode values should remain consistent between
updates to the opcode enum.
This patch repositions I40E_VIRTCHNL_OP_CONFIG_RSS to the end of the enum. In
its current position this opcode displaces the initial value of
I40E_VIRTCHNL_OP_EVENT and will cause PF/VF compatibility issues.
Going forward the expectation is either:
a) All future opcode additions will be added as the last element of the
enum. Once VF drivers start making use of the new commands the virtual
channel version will need to be incremented and drivers will need to
implement a simple version check whereby VF drivers can only load on
PFs with a >= version.
b) or, if needed, design and implement a more complicated API
negotiation capability.
In either case PF drivers should always maintain backwards compatibility with
earlier VF driver versions.

Split the receive hot path code into two, one for packet split and one
for single buffer. This improves receive performance since we only need
to check if the ring is in packet split mode once per NAPI poll time,
not several times per packet. The single buffer code is further improved
by the removal of a bunch of code and several variables that are not
needed. On a receive-oriented test this can improve single-threaded
throughput.
Also refactor the packet split receive path to use a fixed buffer for
headers, like ixgbe does. This vastly reduces the number of DMA mappings
and unmappings we need to do, allowing for much better performance in
the presence of an IOMMU.
Lastly, correct packet split descriptor types now that we are actually
using them.

The steps needed for Lancer's reset/initialization sequence are:
a) wait for SLIPORT_STAUS RDY bit to be set
b) set the SLIPORT_CONTROL IP bit
c) repeat step "a"
The code needed for this sequence is already covered by the be_func_init()
routine (with minor modifications.) So, get rid of the
lancer_test_and_set_rdy_state() and lancer_provisioning_error() routines
that unnecessarily duplicate this code. Also fixed the error recovery
function to take care of these changes

Currently when an error is detected, the queue resources are being cleaned up
in the recovery routine. The resources are better cleaned up in the error
detection routine itself (similar to EEH code.)
So, this patch re-factors error processing logic to follow the following sequence:
- check if there is an error in adapter
- if error,
- cleanup resources
- attempt recovery
The patch renames lancer_recover_func() to be_err_recover() as this
routine will be used in the future for error recovery on Skyhawk too.

The members of be_adapter struct were being allocated in two separate
routines -- be_ctrl_init() and be_stats_init(). Also, some other members
were allocated elsewhere. This patch moves the alloc/free code into
be_drv_init/cleanup() routines. The be_pci_map_bars() routine that was
called from be_ctrl_init() is now called directly from be_probe().
The new routine be_drv_init() will now be the place-holder for allocating
memory for any new be_adapter{} members in the future.
Some routines needed to be moved to provide forward definitions for their
calls.

vlan add/deletes are not notified to userspace today. This patch adds
vlan info to bridge newlink/dellink notifications generated from the
bridge driver. Notifications use the RTEXT_FILTER_BRVLAN_COMPRESSED
flag to compress vlans into ranges whereever applicable.
The size calculations does not take ranges into account for
simplicity. This has the potential for allocating a larger skb than
required.
There is an existing inconsistency with bridge NEWLINK and DELLINK
change notifications. Both generate NEWLINK notifications. Since its
always a NEWLINK notification, this patch includes all vlans the port
belongs to in the notification. The NEWLINK and DELLINK request
messages however only include the vlans to be added and deleted.

- Reduce code duplication by moving WRB-frags setup into a function.
- Do not setup WRB-header before frags are setup, which is unncessary if
there's errors while setting up frags. We should only grab an entry for
the header, setup the frags and if everything is fine setup the header.
- The error cleanup can be moved into a small function.

The WRB header is setup by wrb_fill_hdr() routine. This routine currently
gets some of the WRB params as args and figures out rest of the WRB params
by looking at various fields in skb (like gso, checksum, vlan-tag etc).
All these params could instead be retrieved from the skb into a structure
and passed to this routine. This separates wrb_fill_hdr() to only provide
chip-specific code to fill the WRB. This also makes it simple to support
chips with different WRB formats.
