When using Blue-Flame, BF, the QPN overrides the VLAN, CV, and SV
fields in the WQE. Thus, BF may only be used for QPNs with bits 6,7
unset.
The current ethernet driver code reserves a TX QP range with 256b
alignment.
This is wrong because if there are more than 64 TX QPs in use, QPNs >=
base + 65 will have bits 6/7 set.
This problem is not specific for the Ethernet driver, any entity that
tries to reserve more than 64 BF-enabled QPs should fail. Also, using
ranges is not necessary here and is wasteful.
The new mechanism introduced here will support reservation for "Eth
QPs eligible for BF" for all drivers: bare-metal, multi-PF, and VFs
(when hypervisors support WC in VMs). The flow we use is:
1. In mlx4_en, allocate Tx QPs one by one instead of a range allocation,
and request "BF enabled QPs" if BF is supported for the function
2. In the ALLOC_RES FW command, change param1 to:
a. param1[23:0] - number of QPs
b. param1[31-24] - flags controlling QPs reservation
Bit 31 refers to Eth blueflame supported QPs. Those QPs must have bits
6 and 7 unset in order to be used in Ethernet.
Bits 24-30 of the flags are currently reserved.
When a function tries to allocate a QP, it states the required
attributes for this QP. Those attributes are considered "best-effort".
If an attribute, such as Ethernet BF enabled QP, is a must-have
attribute, the function has to check that attribute is supported
before trying to do the allocation.
In a lower layer of the code, mlx4_qp_reserve_range masks out the bits
which are unsupported. If SRIOV is used, the PF validates those
attributes and masks out unsupported attributes as well. In order to
notify VFs which attributes are supported, the VF uses QUERY_FUNC_CAP
command. This command's mailbox is filled by the PF, which notifies
which QP allocation attributes it supports.

Previously, the mlx4 driver queried the firmware in order to get the
number of supported EQs. Under SRIOV, since this was done before the
driver notified the firmware how many VFs it actually needs, the
firmware had to take into account a worst case scenario and always
allocated four EQs per VF, where one was used for events while the
others were used for completions. Now, when the firmware supports the
asymmetric allocation scheme, denoted by exposing num_sys_eqs > 0 (-->
MLX4_DEV_CAP_FLAG2_SYS_EQS), we use the QUERY_FUNC command to query
the firmware before enabling SRIOV. Thus we can get more EQs and MSI-X
vectors per function. Moreover, when running in the new
firmware/driver mode, the limitation that the number of EQs should be
a power of two is lifted.

If a file opened over a vnode has an advisory lock set at close,
vn_closefile() acquires additional vnode use reference to prevent
freeing the vnode in vn_close(). Side effect is that for device
vnodes, devfs_close() sees that vnode reference count is greater than
one and refuses to call d_close(). Create internal version of
vn_close() which can avoid dropping the vnode reference if needed, and
use this to execute VOP_CLOSE() without acquiring a new reference.
Note that any parallel reference to the vnode would still prevent
d_close call, if the reference is not from an opened file, e.g. due to

This implements hardware assisted quiet IE support. Quiet time is
an optional interval on DFS channels (but doesn't have to be DFS
only channels! sigh) where the station and AP can be quiet in order
to allow for channel utilisation measurements. Typically that's
stuff like radar detection, spectral scan, other-BSS frame sniffing,
checking how busy the air is, etc.
The hardware implements it as one of the generic timers, which is
supplied a period, offset from the trigger period and duration
to stay quiet. The AP can announce quiet time configurations which
change, and so this code also tracks that.
Implementation details:
* track the current quiet time IE
* compare the new one against the previous one - if only the TBTT
counter changes, don't update things
* If tbttcount=1 then program it into the hardware - that is when
it is easiest to program the correct starting offset (one TBTT +
configured offset).
* .. later on check to see if it can be done on any tbttcount
* If the IE goes away then remove the quiet timer and clear the
config
* Upon reset, state change, new beacon - clear quiet time IE
and just let it resync from the next beacon.
History:
This was work done initially by sibridgetech.com in 2011/2012/2013
as part of some FreeBSD wifi DFS contracting work they had for a
third party. They implemented the net80211 quiet time IE pieces
and had some test code for the station side which didn't entirely
use the timers correctly.
I figured out how to use the timers correctly without stopping/starting
the transmit DMA engine each time. When done correctly, the timer
just needs to be programmed once and left alone until the next
configuration change.
So, thanks to Himali Patel and Parthiv Shah for their work way
back then. I finally figured it out and finished it!
TODO:
* Now, I'd rather net80211 did the quiet time IE tracking and parsing,
pushing configurations into the driver is needed. I'll look at
doing that in a subsequent update.
* This doesn't handle multiple quiet time IEs, which will currently
just mess things up. I'll look into supporting that in the future
(at least by only obeying "one" of them, and then ignoring
subsequent IEs in a beacon/probe frame.)
* This also implements the STA side and not the AP side - the AP
side will come later, and involves taking various other intervals
into account (eg the beacon offset for multi-VAP modes, the
SWBA time, etc, etc) as well as obtaining the configuration when
a beacon is configured/generated rather than "hearing" an IE.
* .. investigate supporting quiet IE in mesh, tdma, ibss modes
* .. investigate supporting quiet IE for non-DFS channels
(so this can be done for say, 2GHz channels.)
* Chances are i should commit NULL methods for the ar5210, ar5211 HALs..
Tested:
* AR9380, STA mode - announcing quiet, removing quiet, changing quite
time config, whilst doing iperf testing;
* AR9380, AP mode.

This fix is implementing partition based boundary check for
disk IO and updates disk mediasize (if needed), based on information
from partition table.
As it appeared, the signed int based approach still has corner cases,
and the wrapover based behavior is non-standard.
The idea for this fix is based on two assumptions:
The bug about media size is hitting large (2+TB) disks, lesser disks
hopefully, are not affected.
Large disks are using GPT (which does include information about disk size).
Since our concern is about boot support and boot disks are partitioned,
implementing partition boundaries based IO verification should make the
media size issues mostly disappear.
However, for large disk case, we do have the disk size available from GPT table.
If non-GPT cases will appear, we still can make approximate calculation about
disk size based on defined partition(s), however, this is not the objective
of this patch, and can be added later if there is any need.
This patch does implement disk media size adjustment (if needed) in bd_open(),
and boundary check in bd_realstrategy().

The loader bcache is implementing simple read-ahead to boost the cache.
The bcache is built based on 512B block sizes, and the read ahead is attempting
to read number of cache blocks, based on amount of the free bcache space.
However, there are devices using larger sector sizes than 512B, most obviously
the CD media is based on 2k sectors. This means the read-ahead can not be just
random number of blocks, but we should use value suitable also for use with
larger sectors, as for example, with CD devices, we should read multiple of 2KB.
Since the sector size from disk interface is not too reliable, i guess we can
just use "good enough" value, so the implementation is rounding down the read
ahead block count to be multiple of 16.
This means we have covered sector sizes to 8k.
In addition, the update does implement the end of cache marker, to help to
