In the current code, vendor-specific MADs (e.g with the FDR-10
attribute) are silently dropped by the driver, resulting in timeouts
at the sending side and inability to query/configure the relevant
feature. However, the ConnectX firmware is able to handle such MADs.
For unsupported attributes, the firmware returns a GET_RESPONSE MAD
containing an error status.
For example, for a FDR-10 node with LID 11:
# ibstat mlx4_0 1
CA: 'mlx4_0'
Port 1:
State: Active
Physical state: LinkUp
Rate: 40 (FDR10)
Base lid: 11
LMC: 0
SM lid: 24
Capability mask: 0x02514868
Port GUID: 0x0002c903002e65d1
Link layer: InfiniBand
Extended Port Query (EPI) vendor mad timeouts before the patch:
# smpquery MEPI 11 -d
ibwarn: [4196] smp_query_via: attr 0xff90 mod 0x0 route Lid 11
ibwarn: [4196] _do_madrpc: retry 1 (timeout 1000 ms)
ibwarn: [4196] _do_madrpc: retry 2 (timeout 1000 ms)
ibwarn: [4196] _do_madrpc: timeout after 3 retries, 3000 ms
ibwarn: [4196] mad_rpc: _do_madrpc failed; dport (Lid 11)
smpquery: iberror: [pid 4196] main: failed: operation EPI: ext port info query failed
EPI query works OK with the patch:
# smpquery MEPI 11 -d
ibwarn: [6548] smp_query_via: attr 0xff90 mod 0x0 route Lid 11
ibwarn: [6548] mad_rpc: data offs 64 sz 64

Commit 8d4548f2b ("IB/qib: Default some module parameters optimally")
introduced an issue with older root complexes. They cannot handle the
pcie_caps of 0x51 (MaxReadReq 4096, MaxPayload=256).
A typical diagnostic in this situation reported by syslog contains
the text:
[PCIe Poisoned TLP][Send DMA memory read]
Restore the module paramter default to zero with will avoid any
changes in the root complex.

module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.
It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.

For historical reasons, we allow module_param(bool) to take an int (or
an unsigned int). That's going away.
A few drivers really want an int: they set it to -1 and a parameter
will set it to 0 or 1. This sucks: reading them from sysfs will give
'Y' for both -1 and 1, but if we change it to an int, then the users
might be broken (if they did "param" instead of "param=1").
Use a new 'bint' parser for them.
(ntfs has a different problem: it needs an int for debug_msgs because
it's also exposed via sysctl.)

For IBoE, SLs 0-7 are mapped to Ethernet 802.1Q user priority bits
(pbits) which are part of the VLAN tag, SLs 8-15 are reserved.
Under Ethernet, the ConnectX firmware treats (decode/encode) the four
bit SL field in various constructs such as QPC / UD WQE / CQE as PPP0
and not as 0PPP. This correlates well to the fact that within the
vlan tag the pbits are located in bits 15-13 and not 12-14.
The current code wasn't consistent around that area - the
encoding was correct for the IBoE QPC.path.schedule_queue field,
but was wrong for IBoE CQEs and when MLX header was built.
These inconsistencies resulted in wrong SL <--> wire 802.1Q pbits
mapping, which is fixed by using SL <--> PPP0 all around the place.

Minimize the need for users to have to set module parameters to get
good performance.
The following two parameters are changed:
- rcvhdrcnt to twice the rcvegrcnt
- pcie_caps=0x51
The rcvhdrcnt at twice the egrcount allows the preemptive NAK code
during reception to function in 100% of the cases rather than a sender
jiffies-based timeout.
The pcie_caps default of 0x51 will set the proposed MaxPayload and
MaxReceiveReqest to 256 and 4096 respectively. The capabilities on
the root complex will be used to limit those values.

The current code locks the QP s_lock, followed by the pending_lock, I
guess to to protect against the allocate failing.
This patch only locks the pending_lock, assuming that the empty case
is an exeception, in which case the pending_lock is dropped, and the
original code is executed. This will save a lock of s_lock in the
normal case.
The observation is that the sdma descriptors will deplete at twice the
rate of txreq's, so this should be rare.

For SRIOV, some Hypervisor commands can be executed directly (native = 1).
Others should go through the command wrapper flow (for tracking resource
usage, for example, or for changing some HCA configurations that slaves
need to be notified of).
This patch sets the groundwork for this capability -- adding the correct
value of "native" in each case.
Note that if SRIOV is not activated, this parameter has no effect.

The RC error state flush logic in qib_make_rc_req() could return all
of the acked wqes and potentially have emptied the queue. It would
then unconditionally try return a flush completion via
qib_send_complete() for an invalid wqe, or worse a valid one that is
not queued. The panic results when the completion code tries to
maintain an MR reference count for a NULL MR.
This fix modifies logic to only send one completion per
qib_make_rc_req() call and changing the completion status from
IB_WC_SUCCESS to IB_WC_WR_FLUSH_ERR as the completions progress.
The outer loop will call as many times as necessary to flush the queue.

The num_free field of mthca_buddy has a type of array of unsigned int
while it was allocated as an array of pointers. On 64-bit platforms
this allocates twice more than required. Fix this by allocating the
correct size for the type.
