This patch adds the interrupt handler function, the NAPI poll
function, and its associated helper functions for receiving
accelerated ipoib packets. While we are here, fix the formats
of two error printouts.

Ipoib netdev will share receive contexts with existing VNIC netdev.
To achieve that, a dummy netdev is allocated with hfi1_devdata to
own the receive contexts, and ipoib and VNIC netdevs will be put
on top of it. Each receive context is associated with a single
NAPI object.
This patch adds the functions to receive incoming packets for
accelerated ipoib.

Currently the ipoib UD mtu is restricted to 4K bytes. Remove this
limitation so that the IPOIB module can potentially use an MTU (in UD
mode) that is bounded by the MTU of the underlying device. A field is
added to the ib_port_attr structure to indicate the maximum physical
MTU the underlying device supports.

This is implementation of RSM rule for AIP packets.
AIP rule will use rule RSM2 and will match standard
Infiniband packet containg BTH (LNH==BTH) and
having Dest QPN prefixed with value 0x81. Spread between
receive contexts will be done using source QPN bits.
VNIC and AIP will share receive contexts, so their rules
will point to the same RMT entries and their shared
code is moved to separate functions.
If any of the rules is active RMT mapping will be skipped
for latter.
Changed function hfi1_vnic_is_rsm_full to be more general
and moved it from main header to chip.c.
Changed the order of RSM rules because AIP rule as
more specific one is needed to be placed before more
general QOS rule. Rules are occupying two last RSM
registers.

Adds capability to create a qpn to be recognized as an accelerated
UD QP for ipoib.
This is accomplished by reserving 0x81 in byte[0] of the qpn as the
prefix for these qp types and reserving qpns between 0x810000 and
0x81ffff.
The hfi1 capability mask already contained a flag for the VNIC netdev.
This has been renamed and extended to include both VNIC and ipoib.
The rvt code to allocate qps now recognizes this flag and sets 0x81
into byte[0] of the qpn.
The code to allocate qpns is modified to reset the qpn numbering when it
is detected that a value is located in byte[0] for a UD QP and it is a
qpn being requested for net dev use. If it is a regular UD QP then it is
allowable to have bits set in byte[0] of the qpn and provide the
previously normal behavior.
The code to free the qpn now checks for the AIP prefix value of 0x81 and
removes it from the qpn before being freed so that the lower 16 bit
number can be reused.
This patch requires minor changes in the IB core and ipoib to facilitate
the creation of accelerated UP QPs.

The module parameter for KDETH qpns is being removed in favor
of always using the default value of 0x80 as the qpn prefix.
Defines have been added for various KDETH values including
the prefix of 0x80.
The reserved range now starts at the base value for KDETH
qpns (0x80) and extends up to and including the last qpn for
other reserved QP prefixed types.
Adjust other QP prefixed define names to match KDETH defined
names.

This implements the transmit side of the multiple transmit queue RDMA
netdev used to accelerate ipoib. The receive side remains the ipoib
internal implementation.
The init/unint/open/stop netdev operations are saved off and called by the
versions within the hfi1 netdev in order to initialize the connected mode
resources present in ipoib thus allowing us to switch modes between
datagram and connected.
The datagram queue pair instantiated by the ipoib ulp is used by this
implementation for its queue pair number and to register with multicast.
The above queue pair is not used on transmit other than its qpn as the
verbs layer is skipped and packets are directly submitted to the sdma
engines.

This patch implements the mechanism to accelerate the transmit side of
a multiple transmit queue RDMA netdev by submitting the packets to
the SDMA engine directly instead of sending through the verbs layer.
This patch also changes the UD/SEND_ONLY op to output the entropy value
in byte 0 of deth[1]. UD/SEND_ONLY_WITH_IMMEDIATE uses the previous
behavior with no entropy value being output.
The code in the ipoib rdma netdev which submits tx requests upon
successful submission will call trace_sdma_output_ibhdr to output
the ibhdr to the trace buffer.

The commit noted below fixed a case where a pq is left on the sdma wait
list.
It however missed another case.
user_sdma_send_pkts() has two calls from hfi1_user_sdma_process_request().
If the first one fails as indicated by -EBUSY, the pq will be placed on
the waitlist as by design.
If the second call then succeeds, the pq is still on the waitlist setting
up a race with the interrupt handler if a subsequent request uses a
different SDMA engine
Fix by deleting the first call.
The use of pcount and the intent to send a short burst of packets followed
by the larger balance of packets was never correctly implemented, because
the two calls always send pcount packets no matter what. A subsequent
patch will correct that issue.
