5e84b765f4 Move the /usr/src specific options to src.opts.mk. Move inclusion of
/etc/src.conf to this file as well. Now, it will only affect builds of
/usr/src and not others that use the bsd.*.mk files. Specifically
don't install src.opts.mk so we can catch when it 'leaks' into
bsd.*.mk again and have there be errors when this happens. Future
commits will move to including src.opts.mk instead of bsd.own.mk when
all that's needed is one of the MK_FOO options from src.opts.mk.
Future options should be placed here, unless they directly affect a
bsd.*.mk file, in which case they should be placed in bsd.opts.mk.

60196cda04 Prior to r254304, a separate function, vm_pageout_page_stats(), was used to
periodically update the reference status of the active pages.  This function
was called, instead of vm_pageout_scan(), when memory was not scarce.  The
objective was to provide up to date reference status for active pages in
case memory did become scarce and active pages needed to be deactivated.

The active page queue scan performed by vm_pageout_page_stats() was
virtually identical to that performed by vm_pageout_scan(), and so r254304
eliminated vm_pageout_page_stats().  Instead, vm_pageout_scan() is
called with the parameter "pass" set to zero.  The intention was that when
pass is zero, vm_pageout_scan() would only scan the active queue.  However,
the variable page_shortage can still be greater than zero when memory is not
scarce and vm_pageout_scan() is called with pass equal to zero.
Consequently, the inactive queue may be scanned and dirty pages laundered
even though that was not intended by r254304.  This revision fixes that.

67aaf73997 Modify the RX path to keep the previous RX descriptor around once it's
used.

It turns out that the RX DMA engine does the same last-descriptor-link-
pointer-re-reading trick that the TX DMA engine.  That is, the hardware
re-reads the link pointer before it moves onto the next descriptor.
Thus we can't free a descriptor before we move on; it's possible the
hardware will need to re-read the link pointer before we overwrite
it with a new one.

Tested:

* AR5416, STA mode

TODO:

* more thorough AP and STA mode testing!
* test on other pre-AR9380 NICs, just to be sure.
* Break out the RX descriptor grabbing bits from the RX completion
  bits, like what is done in the RX EDMA code, so ..
* .. the RX lock can be held during ath_rx_proc(), but not across
  packet input.

c669105d17 - Remove net.inet.tcp.reass.overflows sysctl. It counts exactly

2bd073e13b Disable the 'uart_drain()' callback when the emulated receive FIFO is full.
Failing to do this will cause the kevent(2) notification to trigger
continuously and the bhyve(8) mevent thread will hog the cpu until the
characters on the backend tty device are drained.

Also, make the uart backend file descriptor non-blocking to avoid a
select(2) before every byte read from that backend.

c503306dc6 Adjust #if statements inside mprsas_send_smpcmd() to more accurately
reflect when unmapped I/O support was added.

For FreeBSD 10, it arrived just prior to __FreeBSD_version 1000028.
For FreeBSD 9, it arrived just prior to __FreeBSD_version 902001.

Also, fix compiler warnings in mprsas_send_smpcmd() that happen in the
i386 PAE build for non-unmapped I/O builds.  These were fixed in mps(4)
in revision 241145, but didn't make it into the mpr(4) driver.  This
change should only affect FreeBSD versions outside the above revisions,
and thus doesn't affect head.

09fd42cb88 Re-adding an event to a kqueue modifies the parameters of the original event.
However, if the original knote had been disabled then it is not automatically
re-enabled.

Fix this by using EV_ADD to create an mevent and EV_ENABLE to enable it.

Adding a kevent for the first time implicitly enables it so existing callers
of mevent_add() don't need to change.

e5bd159ed5 Break out the multicast programming into its own hardware specific
call, which assumes the hardware is awake.

Turn ath_update_mcast() into a routine that's only called from the
net80211 layer - and it forces the hardware awake first.

This fixes a LOR from the EDMA RX path which calls ath_mode_init()
with the RX lock held - the driver lock can't also be grabbed.
This path assumes that the ath_mode_init() callers all wake up
the NIC first.

e407b67be4 The FreeBSD-SA-14:08.tcp was a lesson on not doing acrobatics with
mixing on stack memory and UMA memory in one linked list.

Thus, rewrite TCP reassembly code in terms of memory usage. The
algorithm remains unchanged.

We actually do not need extra memory to build a reassembly queue.
Arriving mbufs are always packet header mbufs. So we got the length
of data as pkthdr.len. We got m_nextpkt for linkage. And we need
only one pointer to point at the tcphdr, use PH_loc for that.

In tcpcb the t_segq fields becomes mbuf pointer. The t_segqlen
field now counts not packets, but bytes in the queue. This gives
us more precision when comparing to socket buffer limits.
