Rework RX filter programming by providing separate handler for
DP8381[56] and SiS 900/7016 controllers. After r212119, sis(4) no
longer reinitializes controller if ALLMULTI/PROMISC was changed.
However, RX filter handling code assumed some bits of the RX filter
is programmed by driver initialization. This caused ALLMULTI/PROMISC
configuration is ignored under certain conditions.
Fix that issue by reprogramming all bits of RX filter register.
While I'm here follow recommended RX filter programming steps
recommended by National DP8381[56] data sheet(RX filter should be
is disabled before programming).

- Allow IFM_FLAG0 to be set indicating that auto-negotiation with manual
configuration, which is used to work around issues with certain setups
(see r161237) by default, should not be triggered as it may in turn
cause harm in some edge cases.
- Even after masking the media with IFM_GMASK the result may have bits
besides the duplex ones set so just comparing it with IFM_FDX may lead
to false negatives.
- Announce PAUSE support also for manually selected 1000BASE-T, but for
all manually selected media types only in full-duplex mode. Announce
asymmetric PAUSE support only for manually selected 1000BASE-T.
- Simplify setting the manual configuration bits to only once after we
have figured them all out. This also means we no longer unnecessarily
update the hardware along the road.
- Remove a stale comment.

For re(4) controllers that uses new jumbo frame scheme(RTL8168C/D/E),
limit maximum RX buffer size to RE_RX_DESC_BUFLEN instead of
blindly configuring it to 16KB. Due to lack of documentation, re(4)
didn't allow jumbo frame on these controllers. However it seems
controller is confused with jumbo frame such that it can DMA the
received frame to wrong address instead of splitting it into
multiple RX buffers. Of course, this caused panic.
Since re(4) does not support jumbo frames on these controllers,
make controller drop frame that is longer than RE_RX_DESC_BUFLEN
sized frame. Fortunately RTL810x controllers, which do not support
jumbo frame, have no such issues but this change also limited
maximum RX buffer size allowed to RTL810x controllers. Allowing
16KB RX buffer for controllers that have no such capability is
meaningless.

Fix a bug in the client side krpc where it was, sometimes
erroneously, assumed that 4 bytes of data were in the first
mbuf of a list by replacing the bcopy() with m_copydata().
Also, replace the uses of m_pullup(), which can fail for
reasons other than not enough data, with m_copydata().
For the cases where it isn't known that there is enough
data in the mbuf list, check first via m_len and m_length().
This is believed to fix a problem reported by dpd at dpdtech.com
and george+freebsd at m5p.com.

Make sure to always do source address selection on
an unbound socket, regardless of any multicast options.
If an address is specified via a multicast option, then
let it override normal the source address selection.
This fixes a bug where source address selection was
not being performed when multicast options were present
but without an interface being specified.

Apply DMA address space restriction to controllers that have 4GB
DMA boundary bug and runs with PCI-X mode. watchdog timeout was
observed on BCM5704 which lives behind certain PCI-X bridge(e.g.
AMD 8131 PCI-X bridge). It's still not clear whether the root
cause came from that PCI-X bridge or not. The watchdog timeout
indicates the issue is in TX path. If the bridge reorders TX
mailbox write accesses it would generate all kinds of problems but
I'm not sure. This should be revisited.

Extend the section in which interrupts are disabled in the TLB demap
functions, otherwise if we get preempted after checking whether a certain
pmap is active on the current CPU but before disabling interrupts we might
operate on an outdated state as the pmap might have been deactivated in
the meantime. As the same issue may arises when the TLB demap function is
interrupted by a TLB demap IPI, just entering a critical section before
the check isn't sufficient so we have to fully disable interrupts instead.

Since VOP_READDIR() for ZFS does not return monotonically
increasing directory offset cookies, disable the UFS related
loop that skips over directory entries at the beginning of
the block for the experimental NFS server. This loop is
required for UFS since it always returns directory entries
starting at the beginning of the block that
the requested directory offset is in. In discussion with pjd@
and mckusick@ it seems that this behaviour of UFS should maybe
change, with this fix being an interim patch until then.
This patch only fixes the experimental server, since pjd@ is
working on a patch for the regular server.
