IF_ADDR_UNLOCK() across network device drivers when accessing the
per-interface multicast address list, if_multiaddrs. This will
allow us to change the locking strategy without affecting our driver
programming interface or binary interface.
For two wireless drivers, remove unnecessary locking, since they
don't actually access the multicast address list.

When user_frac in the polling subsystem is low it is going to busy the2009-05-30T15:14:44ZAttilio Raoattilio@FreeBSD.org2009-05-30T15:14:44Zurn:sha1:1abcdbd127e95ffe08399ec75a7001edd1ca2f5f
CPU for too long period than necessary. Additively, interfaces are kept
polled (in the tick) even if no more packets are available.
In order to avoid such situations a new generic mechanism can be
implemented in proactive way, keeping track of the time spent on any
packet and fragmenting the time for any tick, stopping the processing
as soon as possible.
In order to implement such mechanism, the polling handler needs to
change, returning the number of packets processed.
While the intended logic is not part of this patch, the polling KPI is
broken by this commit, adding an int return value and the new flag
IFCAP_POLLING_NOCOUNT (which will signal that the return value is
meaningless for the installed handler and checking should be skipped).
Bump __FreeBSD_version in order to signal such situation.

Use m_collapse(9) to collapse mbuf chains instead of relying on2008-01-18T08:32:08ZPyun YongHyeonyongari@FreeBSD.org2008-01-18T08:32:08Zurn:sha1:7eb12306d655acf3ae93902abbcfdbf40253a238
shortest possible chain of mbufs of m_defrag(9). What we want is
chains of mbufs that can be safely stored to a Tx descriptor which
can have up to STGE_MAXTXSEGS mbufs. The ethernet controller does
not need to align Tx buffers on 32bit boundary. So the use of
m_defrag(9) was waste of time.
Implement WOL capability.2008-01-14T07:16:48ZPyun YongHyeonyongari@FreeBSD.org2008-01-14T07:16:48Zurn:sha1:346de09f2a744541ac49c079348005ad130ecb97
- Turn on WOL bits in suspend/shutdown method.
- WOL is disabled in resume routine as WOL can interfere normal
Rx operation.
- Move stge_reset() to stge_init_locked() as resetting hardware
clears configured Rx information which in turn results in
non-working Rx module after suspend/shutdown operation.

If these drivers are setting M_VLANTAG because they are stripping the
layer 2 802.1Q headers, then they need to be re-inserting them so any
bpf(4) peers can properly decode them.
It should be noted that this is compiled tested only.
