43cd61606b Replace several bus_alloc_resource() calls using default arguments with bus_alloc_resource_any()
Since these calls only use default arguments, bus_alloc_resource_any() is the
right call.

2a8c860fe3 In order to reduce use of M_EXT outside of the mbuf allocator and
socket-buffer implementations, introduce a return value for MCLGET()
(and m_cljget() that underlies it) to allow the caller to avoid testing
M_EXT itself.  Update all callers to use the return value.

With this change, very few network device drivers remain aware of
M_EXT; the primary exceptions lie in mbuf-chain pretty printers for
debugging, and in a few cases, custom mbuf and cluster allocation
implementations.

NB: This is a difficult-to-test change as it touches many drivers for
which I don't have physical devices.  Instead we've gone for intensive
review, but further post-commit review would definitely be appreciated
to spot errors where changes could not easily be made mechanically,
but were largely mechanical in nature.

8d864935b6 Run through unifdef(1) with slight hand-editing after. It is obvious,
that the driver is not going to be ever improved in terms of hardware
support, it is going to be only maintained as our kernel APIs change.
Carrying all the compatibility with ancient versions of NetBSD, OpenBSD,
Linux and BSDI, as well as obsoleted FreeBSD versions has no reason.

56b61ca27a Remove ifq_drops from struct ifqueue. Now queue drops are accounted in
struct ifnet if_oqdrops.

Some netgraph modules used ifqueue w/o ifnet. Accounting of queue drops
is simply removed from them. There were no API to read this statistic.

540b1a7238 Clean up SIOCSIFDSTADDR usage from ifnet drivers. The ioctl itself is
extremely outdated, and I doubt that it was ever used for ifnet drivers.
It was used for AF_INET sockets in pre-FreeBSD time.

73e7361eac This driver has two modes, a netgraph mode and an ifnet mode. In the
netgraph mode it used a private timer to drive the transmit watchdog.  In
the ifnet mode it used if_watchdog.  Now it always uses the private timer.

1abcdbd127 When user_frac in the polling subsystem is low it is going to busy the
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.

This driver hasn't compiled for 3 years since the PCI compat shims
were removed, and Lan Media appears to have gone out of business.
These cards appear to be rare (a recent search of ebay had no hits).

Should someone wish to revive this driver, submitting patches to make
it compile plus a testing report will bring it back.
