ubenv import ldvarname=ubvarname
Without the varname= prefix it uses the historical behavior of importing
to the name uboot.ubvarname.
Tested with RTL8188EU and RTL8188CUS in STA mode.

Certain interfaces (e.g. pfsync0) do not have ip6 addresses (in other words,
ifp->if_afdata[AF_INET6] is NULL). Ensure we don't panic when the MTU is
updated.
pfsync interfaces will never have ip6 support, because it's explicitly disabled
in in6_domifattach().

When mp[rs]sas_get_sata_identify returns
MPI2_IOCSTATUS_SCSI_PROTOCOL_ERROR, don't bother retrying. Protocol
errors aren't likely to be fixed by sleeping.
Without this change, a system that generated may protocol errors due
to signal integrity issues was taking more than an hour to boot, due
to all the retries.

In r289315, I added new fields to res_state. This broke binary
backward compatibility. It also broke some ports (and possibly
other code) by requiring the definition of time_t and struct timespec.
Fix these problems by moving the new fields into __res_state_ext.

* Use the interrupt-map property to route interrupts
* Remove the IRQ rman, it's now unneeded
* Support MSI/MSI-X interrupts
With this I'm able to use the two NICs I've tested (em and msk), however
while I can boot with an AHCI devie attached it fails when any drives are
connected.

Currently, in case when npkts >= 2, RSSI and Rx radiotap fields
will be overridden by the next packet. As a result, every packet
from this chain will use the same RSSI / radiotap data.
After this change, RSSI and radiotap structure will be filled
for every frame right before ieee80211_input() call.
Tested with RTL8188EU / RTL8188CUS, STA and MONITOR modes.

restored before returning to the exception handler.
Userland still needs these registers to be restored as they may be changed
by the kernel and we don't currently track these places.
An implementation from rum(4) was used (it looks simpler for me).
Will be used for h/w encryption support.

Before r291643, adding new interface prefix had the following logic:
try_add:
EEXIST && (PINNED) {
try_del(w/o PINNED flag)
if (OK)
try_add(PINNED)
}
In r291643, deletion was performed w/ PINNED flag held which leaded
to new interface prefixes (like ::1) overriding older ones.
Fix this by requesting deletion w/o RTF_PINNED.

LLE structure is mostly unchanged during its lifecycle: there are only 2
things relevant for fast path lookup code:
1) link-level address change. Since r286722, these updates are performed
under AFDATA WLOCK.
2) Some sort of feedback indicating that this particular entry is used so
we send NS to perform reachability verification instead of expiring entry.
The only signal that is needed from fast path is something like binary
yes/no.
The latter is solved by the following changes:
Special r_skip_req (introduced in D3688) value is used for fast path feedback.
It is read lockless by fast path, but updated under req_mutex mutex. If this
field is non-zero, then fast path will acquire lock and set it back to 0.
After transitioning to STALE state, callout timer is armed to run each
V_nd6_delay seconds to make sure that if packet was transmitted at the start
of given interval, we would be able to switch to PROBE state in V_nd6_delay
seconds as user expects.
(in STALE state) timer is rescheduled until original V_nd6_gctimer expires
keeping lle in STALE state (remaining timer value stored in lle_remtime).
(in STALE state) timer is rescheduled if packet was transmitted less that
V_nd6_delay seconds ago to make sure we transition to PROBE state exactly
after V_n6_delay seconds.
As a result, all packets towards lle in REACHABLE/STALE/PROBE states are handled
by fast path without acquiring lle read lock.

requests which page alignment + size is greater than MAXPHYS. Right
now md(4) over vnode would use the physical buffer of the size MAXPHYS
to map a data of size MAXPHYS + page offset of the user buffer. This
typically corrupts next pbuf, or, if the pbuf used was the last pbuf
in the map, the next page after the pbuf's map.
Split request up to the size of io which fits into pbuf KVA with
alignment, and retry if a part of the bio is left unprocessed.
