member access within misaligned address 0xffff9457bc441286 for type
'struct in6_addr' which requires 4 byte alignment
This issue is caused by accessing non-__packed struct in __packed.
This is a[always?] false-positive reported by the sanitizer and there is no
clear non-invasive approach to handle this, without changing ABI of long
term existing code.

it to NULL in the called function does not set it to NULL in the caller.
Actually, the callers of these functions do not do anything with the
special error handling, so drop the unused checks and the NULL assignments
altogether.

function is called from if_init().
- If a multicast entry has range, use ALLMULTI like others.
- Remove ixv_set_promisc() and use ixv_set_multi(). And then, rename
*_set_multi() to *_set_rxfilter(). Same as ixgbe.c.
- The promisc mode can't be enabled if the PF is not in promisc mode.
Identify that state and report it as "the PF may not in promisc mode"
(though it might not be perfect).
A new completion queue entry check incorrectly determined that there was
a Completion Queue entry for a command that was not submitted.
Fix PR kern/54275, PR kern/54503, PR kern/54532.
- Add cchar command to director test language to allow a complex character
to be defined and passed to the slave.
- Removed the distinction between args and returns internally to prevent
confusing the two which leads to errors and/or crashes.
- Converted mutt_test to use the new cchar definition and fixed the
check files for the test.
percpu(9) has a certain memory storage for each CPU and provides it by the piece
to users. If the storages went short, percpu(9) enlarges them by allocating new
larger memory areas, replacing old ones with them and destroying the old ones.
A percpu storage referenced by a pointer gotten via percpu_getref can be
destroyed by the mechanism after a running thread sleeps even if percpu_putref
has not been called.
Tx processing of l2tp(4) uses normally involves sleepable operations so we
must avoid dereferencing a percpu data (struct ifqueue) after executing Tx
processing. Address this situation by having just a pointer to the data in
a percpu storage instead.

Using rtcache, i.e., packet processing, typically involves sleepable operations
such as rwlock so we must avoid dereferencing a rtcache that is directly stored
in a percpu storage during packet processing. Address this situation by having
just a pointer to a rtcache in a percpu storage instead.

It seems l2tp(4) call path is too long for instruction cache. So, dividing
l2tp(4) Tx context improves CPU use efficiency.
After this commit, l2tp(4) throughput gains 10% on my machine(Atom C3000).
