eb956cd041 Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/
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.

c15fccb8f2 - Use the revamped code from the gem(4) PCI front-end, which
doesn't require parts of the Expansion ROM to be copied around,
  for obtaining the MAC address on !OFW platforms.
- Don't unnecessarily cache bus space tag and handle nor RIDs
  in the softcs of the front-ends.

da28723ecd o Disable HMEDEBUG by default.
o Add CTASSERTs ensuring that HME_NRXDESC and HME_NTXDESC are set to
  legal values.
o Use appropriate maxsize, nsegments and maxsegsize parameters when
  creating DMA tags and correct some comments related to them.
o The FreeBSD bus_dmamap_sync(9) supports ored together flags for quite
  some time now so collapse calls accordingly.
o Add missing BUS_DMASYNC_PREREAD when syncing the control DMA maps in
  hme_rint() and hme_start_locked().
o Keep state of the link state and use it to enable or disable the MAC
  in hme_mii_statchg() accordingly as well as to return early from
  hme_start_locked() in case the link is down.
o Introduce a sc_flags and use it to replace individual members like
  sc_pci.
o Add bus_barrier(9) calls to hme_mac_bitflip(), hme_mii_readreg(),
  hme_mii_writereg() and hme_stop() to ensure the respective bit
  has been written before we starting polling on it and for the right
  bits to change.
o Rather just returning in case hme_mac_bitflip() fails and leaving us
  in an undefined state report the problem and move on; chances are
  the requested configuration will become active shortly after.
o Don't call hme_start_locked() in hme_init_locked() unconditionally
  but only after calls to hme_init_locked() when it's appropriate, i.e.
  in hme_watchdog().
o Add a KASSERT which asserts nsegs is valid also to hme_load_txmbuf().
o In hme_load_txmbuf():
  - use a maximum of the newly introduced HME_NTXSEGS segments instead
    of the incorrect HME_NTXQ, which reflects the maximum TX queue
    length, for loading the mbufs and put the DMA segments back onto
    the stack instead of the softc as 16 should be ok there.
  - use the common errno(2) return values instead of homegrown ones,
  - given that hme_load_txmbuf() is allowed to fail resulting in a
    packet drop for quite some time now implement the functionality of
    hme_txcksum() by means of m_pullup(9), which de-obfuscates the code
    and allows to always retrieve the correct length of the IP header, [1]
  - also add a KASSERT which asserts nsegs is valid,
  - take advantage of m_collapse(9) instead of m_defrag(9) for
    performance reasons.
o Don't bother to check whether the interface is running or whether its
  queue is empty before calling hme_start_locked() in hme_tint(), the
  former will check these anyway.
o In hme_intr() call hme_rint() before hme_tint() as gem_tint() may
  take quite a while to return when it calls hme_start_locked().
o Get rid of sc_debug and just check if_flags for IFF_DEBUG directly.
o Add a shadow sc_ifflags so we don't reset the chip when unnecessary.
o Handle IFF_ALLMULTI correctly. [2]
o Use PCIR_BAR instead of a homegrown macro.
o Replace sc_enaddr[6] with sc_enaddr[ETHER_ADDR_LEN].
o Use the maximum of 256 TX descriptors for better performance as using
  all of them has no additional static cost rather than using just half
  of them.

f279f5ced4 - In hme_stop() mask all interrupts.
- In hme_eint() print MIF register contents on MIF interrupts.
- In hme_mifinit() don't bother to preserve the previous MIF config.
  This was mainly done in order to preserve the PHY select bit (external
  or internal PHY) but which only needs to be set as appropriate when
  reading from or writing to the desired PHY in hme_mii_{read,write}reg().
  Similarly don't bother to set the PHY select bit in hme_mii_statchg().
- In hme_mii_{read,write}reg() ignore requests to PHYs other than the
  external and internal PHY one.
- Move enabling/disabling the MII drivers of the external transceiver
  from hme_init_locked() and based on the sheer presence of an external
  to hme_mifinit() and based on the currently selected media, defaulting
  to the internal transceiver when the media hasn't been set, yet.
  Invoke hme_mifinit() from the newly added hme_mediachange_locked() so
  the setting of the MII drivers is updated when changing media.
  These changes keep the MII bus from wedging (which manifests in the HME
  and the PHYs no longer being able to communicate with each other) when
  the PHY device drivers isolate the unused PHY in two-PHY configurations
  as present in f.e. Netra t1 100 while changing media, either from
  hme_init_locked() (see also below) or via ifconfig(8). They also allow
  for using both transceivers/PHYs.
- In the newly added hme_mediachange_locked() also reset the PHYs in two-
  PHY configurations before invoking mii_mediachg(). This is required
  for successfully unisolating the previously unused PHY when switching
  between PHYs.
- Now that changing media should no longer cause problems back out rev.
  1.27 and re-enable setting the current media in hme_init_locked() (see
  the commit message of rev. 1.23 for more info).

These changes are roughly a merge of NetBSD gem.c rev. 1.32 - 1.35 (1.30
was already fixed differently in our 1.36; 1.31 and 1.32 were wrong) with
some parts reworked and things that don't make sense like setting the MII
drivers and restoring the previous MIF and XIF settings in hme_mii_{read,
write}reg() omitted.

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.

fee4d88e0f Fix "Duplicate mbuf free panic".
The cause of "Duplicate mbuf free panic" is in the programming
error of hme_load_txmbuf(). The code path of the panic is the
following.

1. Due to unknown reason DMA engine was freezed. So TX descritors
   of HME become full and the last failed attempt to transmit a
   packet had set its associated mbuf address to hme_txdesc
   structure. Also the failed packet is requeued into interface
   queue structure in order to retrasmit it when there are more
   available TX descritors.

2. Since DMA engine was freezed, if_timer starts to decrement its
   counter. When if_timer expires it tries to reset HME. During
   the reset phase, hme_meminit() is called and it frees all
   associated mbuf with descriptors. The last failed mbuf is also
   freed here.

3. After HME reset completed, HME starts to retransmit packets
   by dequeing the first packet in interface queue.(Note! the
   packet was already freed in hme_meminit()!)

4. When a TX completion interrupt is posted by the HME, driver
   tries to free the successfylly transmitted mbuf. Since the
   mbuf was freed in step2, now we get "Duplicate mbuf free panic".

However, the real cause is in DMA engine freeze. Since no fatal
errors reported via interrupts, there might be other cause of
the freeze. I tried hard to understand the cause of DMA engine
freeze but couldn't find any clues. It seems that the freeze
happens under very high network loads(e.g. 7.5-8.0 MB/s TX speed).

Though this fix is not enough to eliminate DMA engine freeze it's
better than panic.

be063afc20 Some changes related to reading the MAC-address from the VPD on systems
without Open Firmware:
- The PCI data structure of some HME PROMs contains a non-zero interface
  revision in the class code. Thus remove the checks for matching class
  code and PCI data structure length and revsion. These were pretty much
  useless anyway as we only really need the pointer to the VPD which is
  located before the structure length and revision fields.
- On Sun QFE (Quad FastEthernet) cards read the Nth MAC-address for the
  Nth HME controller instead of always the first one for all four HMEs. [1]
- Improve the comment describing the used VPD format to better reflect
  reality.

f348e5ac4b Make hme(4), i.e. the PCI-variant, MI by reading the MAC address on sytems
without Open Firmware directly instead of using OF_getetheraddr(). This is
a bit painful though, as the MAC address is contained in the NA field of
the VPD of the EBus bridge, which is is another function of the same chip.
To make it worse, the VPD of the EBus bridge can't be accessed via the PCI
capability pointer but has to be digged out from the Boot PROM and has a
non-standard format.
The PCI VPD struct and macros used here should be part of the FreeBSD PCI
code nevertheless.

26280d88d7 - Introduce an ofw_bus kobj-interface for retrieving the OFW node and a
subset ("compatible", "device_type", "model" and "name") of the standard
  properties in drivers for devices on Open Firmware supported busses. The
  standard properties "reg", "interrupts" und "address" are not covered by
  this interface because they are only of interest in the respective bridge
  code. There's a remaining standard property "status" which is unclear how
  to support properly but which also isn't used in FreeBSD at present.
  This ofw_bus kobj-interface allows to replace the various (ebus_get_node(),
  ofw_pci_get_node(), etc.) and partially inconsistent (central_get_type()
  vs. sbus_get_device_type(), etc.) existing IVAR ones with a common one.
  This in turn allows to simplify and remove code-duplication in drivers for
  devices that can hang off of more than one OFW supported bus.
- Convert the sparc64 Central, EBus, FHC, PCI and SBus bus drivers and the
  drivers for their children to use the ofw_bus kobj-interface. The IVAR-
  interfaces of the Central, EBus and FHC are entirely replaced by this. The
  PCI bus driver used its own kobj-interface and now also uses the ofw_bus
  one. The IVARs special to the SBus, e.g. for retrieving the burst size,
  remain.
  Beware: this causes an ABI-breakage for modules of drivers which used the
  IVAR-interfaces, i.e. esp(4), hme(4), isp(4) and uart(4), which need to be
  recompiled.
  The style-inconsistencies introduced in some of the bus drivers will be
  fixed by tmm@ in a generic clean-up of the respective drivers later (he
  requested to add the changes in the "new" style).
- Convert the powerpc MacIO bus driver and the drivers for its children to
  use the ofw_bus kobj-interface. This invloves removing the IVARs related
  to the "reg" property which were unused and a leftover from the NetBSD
  origini of the code. There's no ABI-breakage caused by this because none
  of these driver are currently built as modules.
  There are other powerpc bus drivers which can be converted to the ofw_bus
  kobj-interface, e.g. the PCI bus driver, which should be done together
  with converting powerpc to use the OFW PCI code from sparc64.
- Make the SBus and FHC front-end of zs(4) and the sparc64 eeprom(4) take
  advantage of the ofw_bus kobj-interface and simplify them a bit.

66764b4ce9 The Sun hme hardware supposedly supports Tx frames up to 65535 octets,
and Rx frames up to 8191 octets, so it is perfectly capable of supporting

Thus, make it support VLAN `oversize' frames.
