Alas, we shouldn't rename the macro to VLAN_TAG_LVALUE()

- Add locked variants of start(), init(), ifmedia_upd(), and poll() and stop
recursing on the driver lock.
- Add locking to ifmedia_upd() and ifmedia_sts().
- Use callout_*() instead of timeout/untimeout.
- Fix locking in ioctl().

check the domain-name parameter according to the rules for "search"
strings as documented in resolv.conf(5). Specifically, the string must
be no more than 256 bytes long and contain no more than six valid domain
names separated by white space.
The previous unchecked values could result in a mangled resolv.conf
file which could effectively deny access to local sites. This is not
a security issue as rogue dhcp servers could already do this without
sending invalid strings.

EACCES, EPERM or EROFS then gracefully downgrade the access to read only. Also

- Make callouts protected by mutex. Now callouts count as

1. Walk the absolute list in reverse to prefer duplicated levels that have
a lower absolute setting, i.e. 800 Mhz/50% is better than 1600 Mhz/25% even
though both have the same actual frequency. This also removes the need to
check for already-modified levels since by definition, those will be added
later in the sorted list.
2. Compare the absolute settings for derived levels and don't use the new
level if it's higher. For example, a level of 800 Mhz/75% is preferable to
1600 Mhz/25% even though the latter has a lower total frequency.
This work is based on a patch from the submitter but reworked by myself.

Copies the data portion of mbuf (chain) n starting from offset off
for length len to mbuf (chain) m. Depending on prep the copied
data will be appended or prepended. The function ensures that the
mbuf (chain) m will be fully writeable by making real (not refcnt)
copies of mbuf clusters. For the prepending the function returns
a pointer to the new start of mbuf chain m and leaves as much
leading space as possible in the new first mbuf.
