76039bc84f The r48589 promised to remove implicit inclusion of if_var.h soon. Prepare
to this event, adding if_var.h to files that do need it. Also, include
all includes that now are included due to implicit pollution via if_var.h

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.

7cf545d0a1 - Add a private timer to drive the transmit watchdog instead of using
if_watchdog and if_timer.
- Fix some issues in detach for sn(4), ste(4), and ti(4).  Primarily this
  means calling ether_ifdetach() before anything else.

# My reading of the docs suggests this can only happen on 10Base5 and
# 10Base2 setups (and maybe only the former), which I can't test

e89da24b3d Two refinements to the 3c1 support:
1) Flag it and only access that command on the 3c1
2) The TX PLL appears to power down when not in use, so we have to power
   it back up when we've been idle.  Do this at the start of ifstart.
   Otherwise we fall off the net.

52fcedff50 o Report ethernet status for at least 10BaseT media. Since I don't
have other media to test against, I've left that media reporting
  unchanged.
o Enable the TX_PLL when we enable TX.  This is harmless on most
  cards, but required to get the 3c1 CF card working.  Power savings
  could be had by managing this better, but for now it gets my card
  working.

4a0d6638b3 - Store pointer to the link-level address right in "struct ifnet"
rather than in ifindex_table[]; all (except one) accesses are
  through ifp anyway.  IF_LLADDR() works faster, and all (except
  one) ifaddr_byindex() users were converted to use ifp->if_addr.

- Stop storing a (pointer to) Ethernet address in "struct arpcom",
  and drop the IFP2ENADDR() macro; all users have been converted
  to use IF_LLADDR() instead.

ad4f426ef6 Make sure that we call if_free(ifp) after bus_teardown_intr. Since we
could get an interrupt after we free the ifp, and the interrupt
handler depended on the ifp being still alive, this could, in theory,
cause a crash.  Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.

13f4c340ae Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

880266e041 Minor cleanup of ep driver and pccard attachment:
o Grab the MAC address out of the CIS if the card has the special
  3Com 0x88 tuple.  Most 3Com cards don't have this tuple, but we
  prefer it to the eeprom since it only appears to be present when
  the eeprom doesn't have the info.  So far, I've only observed this
  on my 3C362 and 3C362B cards, but the NetBSD driver implies that
  the 3C362C also has this tuple, and that some 3C574 cards do too (none
  of mine do).  ep_pccard_mac was written after looking at the NetBSD
  code.
o Store the enet addr in the softc for this device, so we can use the
  overridden MAC to set the station address.
o Create a routine to set the station address and use it where we need it.
o setup the cmd shitfs and such before we call ep_alloc(), and remove
  setting up the cmd shift value there.  It initializes to 0, and those
  attachments that need to frob it do so before calling ep_alloc.
o Remove some obsolete comments
o No longer a need to export ep_get_macaddr, so make it static
o ep_alloc already grabs the EEPROM id, so we don't need to grab it again
  in ep_pccard_attach.
o eliminate unit, it isn't needed, fix some printfs to be device_printf
  instead.

c4af929fb7 o When calling ep_get_macaddr(), provide it a local buffer. Add a comment
that says why we do this (or rather, explains that it is some voodoo magic
  that's poorly understood).  The local buffer fixes the crash on attach.
o Rename get_e() to ep_get_e() to avoid namespace pollution.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

c7d24cc1a2 Fix a race condition that was introduced since pccbb interrupts are
flag'ed INTR_MPSAFE.  In ep_if_start(), use the IF_DEQUEUE macro to
grab the next mbuf to send, and use IF_PREPEND if the card is busy
and we actually can't handle it right now.

The old code was first getting the mbuf by taking it from the queue
without using the macros, thus without locking, and without removing
it from the queue either.  It was later assuming that IF_DEQUEUE would
give him this same mbuf.
