Replace diagnostic printf()s by assertions. Use consistent style for
similar assertions.
MFC revision 1.545
Remove stale KSE code.
MFC revision 1.580
Use FOREACH_PROC_IN_SYSTEM instead of using its unrolled form.
Introduce pmap_try_insert_pv_entry(), a function that conditionally
creates a pv entry if the number of entries is below the high water mark
for pv entries.
Use pmap_try_insert_pv_entry() in pmap_copy() instead of
pmap_insert_entry(). This avoids possible recursion on a pmap lock in
get_pv_entry().
Eliminate the explicit low-memory checks in pmap_copy(). The check that
the number of pv entries was below the high water mark was largely
ineffective because it was located in the outer loop rather than the
inner loop where pv entries were allocated. Instead of checking, we
attempt the allocation and handle the failure.
Add msk(4), a driver for Marvell/SysKonnect Yukon II Gigabit Ethernet
controller. Due to lack of documentation, this driver is based on the
code from sk(4) and Marvell's myk(4) driver for FreeBSD. I've also
adopted the OpenBSD interface name, msk(4) in order to reduce naming
differences between BSDs.
Acquiring smp_ipi_mtx on every call to pmap_invalidate_*() is wasteful.
For example, during a buildworld more than half of the calls do not
generate an IPI because the only TLB entry invalidated is on the calling
processor. This revision pushes down the acquisition and release of
smp_ipi_mtx into smp_tlb_shootdown() and smp_targeted_tlb_shootdown() and
instead uses sched_pin() and sched_unpin() in pmap_invalidate_*() so that
thread migration doesn't lead to a missed TLB invalidation.
Eliminate unnecessary invalidations of the entire TLB by pmap_remove().
Specifically, on mappings with PG_G set pmap_remove() not only performs
the necessary per-page invlpg invalidations but also performs an
unnecessary invalidation of the entire set of non-PG_G entries.

Log:
Give a chance for packet to appear with a correct input interfaces
in case of multiple interfaces with the same MAC in the same bridge.
This commit do not solve the entire problem. Only case where packet
arrived from such interface.

Mention a limitation that was inherted from RFC1952, making
it impossible to obtain correct file size from a file that
is larger than 4GB before compression.
PR: bin/110329
KERN_PROC_ALL produces a kinfo_proc for each thread in a process, which
caused fstat to produce duplicated output for threaded processes. Instead
use KERN_PROC_PROC to get just one kinfo_proc per process.
rev. 1.17
o style(9) fixes
rev. 1.18
o Add support code for newer Marvell PHYs.
o Remove unused static global variable e1000phy_debug.
o Take advantage of mii_phy_dev_probe().
o Use MII_ANEGTICKS/MII_ANEGTICKS_GIGE instead of magic number 5.
o Add IFM_NONE as e1000phy(4) supports it without issues.
o Nuke magic PHY programming sequence in PHY reset and follow correct
reset sequence. [1]
o Make manual media selection work for all supported media types.
o Don't set MIIF_NOISOLATE so e1000phy(4) can be used in
configurations with multiple PHYs.
o In 1000baseT, when setting the link manually, one side must be the
master and the other the slave. If LINK0 is set, program the PHY
to be a master, otherwise it's a slave.
o When we lost a link, reset mii_ticks immediately so it correctly
check number of seconds elapsed in autonegotiation phase.
o Announce link loss right after it happens.
o After kicking autonegotiation, report PHY status instead of
returning immediatly.
o When link state check is in progress, check auto negotiation
completion bit only when auto negotiation is enbaled.
o When PHY is resolved to a master, show it with IFM_FLAG2.
- Support for BCM5754/5755/5786/5787.
- Support for IPMI/ASF mode (disabled by default)
- Fix lots of bugs including style(9) nits.
Tested by: net, stable
- style(9) cleanup
- Use separate thread for servicing dummynet(4).
Utilize taskqueue(9) API.
- Convert
net.inet.ip.dummynet.curr_time
net.inet.ip.dummynet.searches
net.inet.ip.dummynet.search_steps
to SYSCTL_LONG nodes. It will prevent frequent wrap around on 64bit archs.
- Implement simple mechanics for dummynet(4) internal time correction.
Under certain circumstances (system high load, dummynet lock contention, etc)
dummynet's tick counter can be significantly slower than it should be.
(I've observed up to 25% difference on one of my production servers).
Since this counter used for packet scheduling, it's accuracy is vital for
precise bandwidth limitation.
Introduce new sysctl nodes:
net.inet.ip.dummynet.
tick_lost - number of ticks coalesced by taskqueue thread.
tick_adjustment - number of time corrections done.
tick_diff - adjusted vs non-adjusted tick counter difference
tick_delta - last vs 'standard' tick differnece (usec).
tick_delta_sum - accumulated (and not corrected yet) time
difference (usec).
- Use non-recursive mutex. MTX_RECURSE is unnecessary since rev. 1.70
- Pay respect to net.isr.direct: use netisr_dispatch() instead of ip_input()
- purge_flow_set():
Do not leak memory while purging queues which are not bound to pipe.
* Remove unused pathlen argument from write_entry function.
* Fix logic bug in deciding if do_chdir should be called.
* Don't consider an lstat(2) failure to be an error.
* Correct warning message when lstat(2) fails.
When dispatching frames saved on the power save queue to a
station exiting power save mode prepend them to the driver's
send q instead of appending them. This insures the packets
are not misordered wrt any packets already q'd for the station.
This corrects a problem noticed when using a VoIP phone talking
to an ath card in ap mode; the misordered packets caused noise.
