e50d35e6c6 Add new tunable 'net.link.ifqmaxlen' to set default send interface
queue length. The default value for this parameter is 50, which is
quite low for many of today's uses and the only way to modify this
parameter right now is to edit if_var.h file. Also add read-only
sysctl with the same name, so that it's possible to retrieve the
current value.

3d32c12abf Always use a private timer instead of if_watchdog and if_timer to drive
the transmit watchdog.  These drivers already used a private timer when
compiled to use Netgraph.  This change just makes them always use the
private timer.  Note that these drivers do not compile and are disconnected
from the build due to TTY changes.

cdb31d3351 Remove debug.ce.mpsafenet: we no longer support running the network
stack with conditional Giant acquisition, and IFF_NEEDSGIANT will
be removed in the near future.

6bfa9a2d66 Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.

This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.

33d2bb9ca3 First in a series of changes to remove the now-unused Giant compatibility
framework for non-MPSAFE network protocols:

- Remove debug_mpsafenet variable, sysctl, and tunable.
- Remove NET_NEEDS_GIANT() and associate SYSINITSs used by it to force
  debug.mpsafenet=0 if non-MPSAFE protocols are compiled into the kernel.
- Remove logic to automatically flag interrupt handlers as non-MPSAFE if
  debug.mpsafenet is set for an INTR_TYPE_NET handler.
- Remove logic to automatically flag netisr handlers as non-MPSAFE if
  debug.mpsafenet is set.
- Remove references in a few subsystems, including NFS and Cronyx drivers,
  which keyed off debug_mpsafenet to determine various aspects of their own
  locking behavior.
- Convert NET_LOCK_GIANT(), NET_UNLOCK_GIANT(), and NET_ASSERT_GIANT into
  no-op's, as their entire behavior was determined by the value in
  debug_mpsafenet.
- Alias NET_CALLOUT_MPSAFE to CALLOUT_MPSAFE.

Many remaining references to NET_.*_GIANT() and NET_CALLOUT_MPSAFE are still
present in subsystems, and will be removed in followup commits.

0dea849ae9 Various bpf(4) related fixes to catch places up to the new bpf(4)
semantics.
- Stop testing bpf pointers for NULL.  In some cases use
  bpf_peers_present() and then call the function directly inside the
  conditional block instead of the macro.
- For places where the entire conditional block is the macro, remove the
  test and make the macro unconditional.
- Use BPF_MTAP() in if_pfsync on FreeBSD instead of an expanded version of
  the old semantics.

acd3428b7d Sweep kernel replacing suser(9) calls with priv(9) calls, assigning
specific privilege names to a broad range of privileges.  These may
require some future tweaking.
