Later on, in r201282, this check morphed to other code, but
message "proxy entry exists for non 802 device" still left,
and now it is printed in a case if route prefix found is
equal to current address being added. In other words, when
we are trying to add ARP entry for a network address. The
message is absolutely unrelated and disappointing in this
case.
I don't see anything bad with setting ARP entries for
network addresses. While useless in usual network,
in a /31 RFC3021 it may be necessary. This, remove this code.

- Change shm file descriptors to track the pathname they are associated
with and add a shm_path() method to copy the path out to a caller-supplied
buffer.
- Use the fo_stat() method of shared memory objects and shm_path() to
export the path, mode, and size of a shared memory object via
struct kinfo_file.
- Add a struct shmstat to the libprocstat(3) interface along with a
procstat_get_shm_info() to export the mode and size of a shared memory
object.
- Change procstat to always print out the path for a given object if it
is valid.
- Teach fstat about shared memory objects and to display their path,
mode, and size.

Remove the magic mfi_array is 288 bytes and just use the

Change reporting of a "SYSTEM" disk to "JBOD" to match
LSI MegaCli and firmware reporting.
This means that fiutil command to "create jbod" is now a

LSI defines JBOD to be. This should be fixed in the future
and support added to really create LSI JBOD and enable that
feature on cards that support it.
First cut of new HW support from LSI and merge into FreeBSD.

case SCI_FAILURE_TIMEOUT:

This is because the switch is done on a SCI_TASK_STATUS enum type, but
the SCI_FAILURE_TIMEOUT value belongs to SCI_STATUS instead.
Because the list of SCI_TASK_STATUS values cannot be modified at this
time, use the simplest way to get rid of this warning, which is to cast
the switch argument to int. No functional change.

- Don't malloc() new MCA records for machine checks logged due to a
CMCI or MC# exception. Instead, use a pre-allocated pool of records.
When a CMCI or MC# exception fires, schedule a swi to refill the pool.
The pool is sized to hold at least one record per available machine
bank, and one record per CPU. This should handle the case of all CPUs
triggering a single bank at once as well as the case a single CPU
triggering all of its banks. The periodic scans still use malloc()
since they are run from a safe context.
- Since we have to create an swi to handle refills, make the periodic scan
a second swi for the same thread instead of having a separate taskqueue
thread for the scans.

- Do not define the foo_start() methods or set if_start in the ifnet if
multiq transmit is enabled. Also, set if_transmit and if_qflush before
ether_ifattach rather than after when multiq transmit is enabled. This
helps to ensure that the drivers never try to mix different transmit
methods.
- Properly restart transmit during resume. igb(4) was not restarting it
at all, and em(4) was restarting even if the link was down and was
calling the wrong method if multiq transmit was enabled.
- Remove all the 'more' handling for transmit completions. Transmit
completion processing does not have a processing limit, so it always
runs to completion and never has more work to do when it returns.
Instead, the previous code was returning 'true' anytime there were
packets in the queue that weren't still in the process of being
transmitted. The effect was that the driver would continuously
reschedule a task to process TX completions in effect running at 100%
CPU polling the hardware until it finished transmitting all of the
packets in the ring. Now it will just wait for the next TX completion
interrupt.
- Restart packet transmission when the link becomes active.
- Fix the MSI-X queue interrupt handlers to restart packet transmission if
there are pending packets in the relevant software queue (IFQ or buf_ring)
after processing TX completions. This is the root cause for the OACTIVE
hangs as if the MSI-X queue handler drained all the pending packets from
the TX ring, nothing would ever restart it. As such, remove some
previously-added workarounds to reschedule a task to poll the TX ring
anytime OACTIVE was set.

This change also workarounds dhclient's link state handling bug by
not giving current link status.
Unlike other controllers, ale(4)'s PHY hibernation perfectly works
such that driver does not see a valid link if the controller is not
brought up. If dhclient(8) runs on ale(4) it will blindly waits
until link UP and then gives up after 10 seconds. Because
dhclient(8) still thinks interface got a valid link when IFM_AVALID
is not set for selected media, this change makes dhclient initiate
DHCP without waiting for link UP.
needs to defer link state handling.
While I'm here, mark IFF_DRV_RUNNING before changing media. If
link is established without any delay, that link state change
handling could be lost.
that revision, the bswapXX_const() macros were renamed to bswapXX_gen().
Also, bswap64_gen() was implemented as two calls to bswap32(), and
similarly, bswap32_gen() as two calls to bswap16(). This mainly helps
our base gcc to produce more efficient assembly.
However, the arguments are not properly masked, which results in the
wrong value being calculated in some instances. For example,
bswap32(0x12345678) returns 0x7c563412, and bswap64(0x123456789abcdef0)
returns 0xfcdefc9a7c563412.
Fix this by appropriately masking the arguments to bswap16() in
bswap32_gen(), and to bswap32() in bswap64_gen(). This should also
silence warnings from clang.

bridges. Rather than blindly enabling the windows on all of them, only
enable the window when an MSI interrupt is enabled for a device behind
the bridge, similar to what already happens for HT PCI-PCI bridges.
To implement this, each x86 Host-PCI bridge driver has to be able to
locate it's actual backing device on bus 0. For ACPI, use the _ADR
method to find the slot and function of the device. For the non-ACPI
case, the legacy(4) driver already scans bus 0 looking for Host-PCI
bridge devices. Now it saves the slot and function of each bridge that
it finds as ivars that the Host-PCI bridge driver can then use in its
pcib_map_msi() method.
This fixes machines where non-MSI interrupts were broken by the previous
round of HT MSI changes.

Right now ath_txq_sched() is mainly called from the TX ath_tx_processq()
routine, which is (mostly) done as part of the taskqueue. It shouldn't
be called outside the taskqueue.
But now that I'm about to flip back on BAR TX, I'm going to start
stressing the ath_tx_tid_pause() and ath_tx_tid_resume() paths.
What I don't want to have happen is a reschedule of the TID traffic
_during_ the completion of TX frames.
Ideally I'd like to have a way to flag back up to the processing code
that the current hardware queue should be rechecked for software TID
queue frames. But for now, this should suffice for the BAR TX case.
I may eventually delete this code once I've brought some further
sanity to the general TX queue/completion path.
