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.

edd033746c Remove the dual-address cycle stuff. DAC is used to allow a bus master
device to access 64-bit addresses from a 32-bit PCI bus. While the
RealTek manual says you can set this bit and the chip will perform
DAC only if you give it a DMA address with any of the upper 32
bits set, this appears not to be the case. If I turn on the DAC
bit, the chip sets the 'system error' bit in the status register
when I to do a DMA on my Athlon test box with 32-bit PCI bus (VIA
chipset) even though I only have 128MB of physical memory, and thus
can never give the chip a 64-bit address.

Obviously, I can't just set it and forget it, so until I figure
out the right rule for when it's safe/necessary to enable it, keep
it turned off.

7cae6651cf In re_diag(), there's no need for us to call re_start() ourselves:
IF_HANDOFF() does it for us behind the scenes. Remove the extra call
to re_start() otherwise we try to transmit twice.

In re_encap(), fix the code that guards against consuming too many
descriptors in the TX ring so that it actually works. With the
new 8169S chip, I was able to hit a corner case that drained the
free descriptor count all the way to 0. This is not supposed to
be possible.

c2c6548b3a Teach the re(4) driver about the CFG2 register, which tells us whether
we're on a 32-bit/64-bit bus or not. Use this to decide if we should
set the PCI dual-address cycle enable bit in the C+ command register.
(Enabling DAC on a 32-bit bus seems to do bad things.)

Also, initialize the C+ command register early in the re_init() routine.
The documentation says this register should be configured first.

804af9a1af Toggle the interface on and off before starting the diag test. This
seems to be necessary for the 8139C+ under certain circumstances, and
doesn't appear to hurt the other chips. (In the failure case, the
packet would be sent through the TX DMA ring but not get echoed
back. I suspect this has something to do with the link state changing
unexpectedly.)

abc8ff44d3 - For the 8169 chips, read the station address by forcing an EEPROM
autoload and then copying the contends of the station address
  registers. For some reason, reading the EEPROM on the 8169S doesn't
  work right. This gets around the problem, and allows us to read
  the station address correctly on the 8169S.

- Insert a delay after initiating packet transmition in re_diag() to
  allow lots of time for the frame to echo back to the host, and wait
  for both the 'RX complete' and 'timeout expired' bits in the ISR
  register to be set.

- Deal more intelligently with the fact that the frame length
  field in the RX descriptor is a different width on the 8139C+
  than it is on the 8169/8169S/8110S

- For the 8169, you have to set bit 17 in the TX config register
  to enter digital loopback mode, but for the 8139C+, you have to
  set both bits 17 and 18. Take this into account so that re_diag()
  works properly for both types of chips.

9bac70b851 Add a PHY driver to support the built-in gigE PHY in the 8169S/8110S
ethernet chips. This driver is pretty simple, however it contains
special DSP initialization code which is needed in order to get
the chip to negotiate a gigE link. (This special initialization
may not be needed in subsequent chip revs.) Also:

- Fix typo in if_rlreg.h (RL_GMEDIASTAT_1000MPS -> RL_GMEDIASTAT_1000MBPS)

- Deal with shared interrupts in re_intr(): if interface isn't up,
  return.

- Fix another bug in re_gmii_writereg() (properly apply data field mask)

- Allow PHY driver to read the RL_GMEDIASTAT register via the
  re_gmii_readreg() register (this is register needed to determine
  real time link/media status).

69a6b7fb50 Update hardware revision table. 0x04000000 appears to be the revision
for the 8169S, according to my sample board. The RealTek Linux driver
mentions 0x00800000. I'm assigning this to the 8110S until I get
more info on it. (The (preliminary) RealTek docs only say that 8169S/8110S
chips will have some combination of those two bits set, but doesn't say
exactly what bit combination goes with which chip variant.)

a94100fa9b Take the support for the 8139C+/8169/8169S/8110S chips out of the
rl(4) driver and put it in a new re(4) driver. The re(4) driver shares
the if_rlreg.h file with rl(4) but is a separate module. (Ultimately
I may change this. For now, it's convenient.)

rl(4) has been modified so that it will never attach to an 8139C+
chip, leaving it to re(4) instead. Only re(4) has the PCI IDs to
match the 8169/8169S/8110S gigE chips. if_re.c contains the same
basic code that was originally bolted onto if_rl.c, with the
following updates:

- Added support for jumbo frames. Currently, there seems to be
  a limit of approximately 6200 bytes for jumbo frames on transmit.
  (This was determined via experimentation.) The 8169S/8110S chips
  apparently are limited to 7.5K frames on transmit. This may require
  some more work, though the framework to handle jumbo frames on RX
  is in place: the re_rxeof() routine will gather up frames than span
  multiple 2K clusters into a single mbuf list.

- Fixed bug in re_txeof(): if we reap some of the TX buffers,
  but there are still some pending, re-arm the timer before exiting
  re_txeof() so that another timeout interrupt will be generated, just
  in case re_start() doesn't do it for us.

- Handle the 'link state changed' interrupt

- Fix a detach bug. If re(4) is loaded as a module, and you do
  tcpdump -i re0, then you do 'kldunload if_re,' the system will
  panic after a few seconds. This happens because ether_ifdetach()
  ends up calling the BPF detach code, which notices the interface
  is in promiscuous mode and tries to switch promisc mode off while
  detaching the BPF listner. This ultimately results in a call
  to re_ioctl() (due to SIOCSIFFLAGS), which in turn calls re_init()
  to handle the IFF_PROMISC flag change. Unfortunately, calling re_init()
  here turns the chip back on and restarts the 1-second timeout loop
  that drives re_tick(). By the time the timeout fires, if_re.ko
  has been unloaded, which results in a call to invalid code and
  blows up the system.

  To fix this, I cleared the IFF_UP flag before calling ether_ifdetach(),
  which stops the ioctl routine from trying to reset the chip.

- Modified comments in re_rxeof() relating to the difference in
  RX descriptor status bit layout between the 8139C+ and the gigE
  chips. The layout is different because the frame length field
  was expanded from 12 bits to 13, and they got rid of one of the
  status bits to make room.

- Add diagnostic code (re_diag()) to test for the case where a user
  has installed a broken 32-bit 8169 PCI NIC in a 64-bit slot. Some
  NICs have the REQ64# and ACK64# lines connected even though the
  board is 32-bit only (in this case, they should be pulled high).
  This fools the chip into doing 64-bit DMA transfers even though
  there is no 64-bit data path. To detect this, re_diag() puts the
  chip into digital loopback mode and sets the receiver to promiscuous
  mode, then initiates a single 64-byte packet transmission. The
  frame is echoed back to the host, and if the frame contents are
  intact, we know DMA is working correctly, otherwise we complain
  loudly on the console and abort the device attach. (At the moment,
  I don't know of any way to work around the problem other than
  physically modifying the board, so until/unless I can think of a
  software workaround, this will have do to.)

- Created re(4) man page

- Modified rlphy.c to allow re(4) to attach as well as rl(4).

Note that this code works for the sample 8169/Marvell 88E1000 NIC
that I have, but probably won't work for the 8169S/8110S chips.
RealTek has sent me some sample NICs, but they haven't arrived yet.
I will probably need to add an rlgphy driver to handle the on-board
PHY in the 8169S/8110S (it needs special DSP initialization).
