67155fb0b2 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.

c9a02b4657 - Consistently use if_printf() only in interface methods: if_start(),
if_watchdog, etc., or in functions used only in these methods.
  In all other functions in the driver use device_printf().
- Use __func__ instead of typing function name.

f70f525b49 - 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.

9070151776 Fixup locking in if_my(4) and mark it MPSAFE:
- Add locked variants of my_start() and my_init().
- Assert that the lock is held in several places rather than recursing.
- Overhaul failure case handling in my_attach() so that it will actually
  clean up completely in each of the failure cases.
- Setup the interrupt after ether_ifattach() in my_attach().
- Remove unused callout handle from softc.
- Free the metadata for the descriptors my_in detach() (we leaked it
  before).
- Fix locking in my_ioctl().
- Remove spls.

156a2cfb5d - Remove pre-new-bus code under #if 0 and some other rotted code under
#if 0.
- Use pci_enable_busmaster() to enable busmastering instead of frobbing
  the command register directly.
- Don't check to see if memory or I/O can be enabled by writing to the
  command register.  The PCI bus driver's bus_alloc_resource() method
  already checks this and will fail if it can't enable the bit.

f9ad9d9fa7 - Use if_printf() and device_printf() instead of outputting my%d:
everywhere.  This means that my_unit is no longer used as well.  The
  watchdog routine now also prints 'my0: ...' rather than 'm0x0: ...'.
- Don't bzero the softc and don't try to free it in detach or if attach
  fails.
- A whitespace fix.

5d770a09e8 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.

567ba9b00a 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.

29f07789b1 Drop the driver lock around calls to if_input to avoid a LOR when
the packets are immediately returned for sending (e.g.  when bridging

ae5ec43081 Try to create some sort of consistency in how the routings to find the
multicast hash are written.  There are still two distinct algorithms used,
and there actually isn't any reason each driver should have its own copy
of this function as they could all share one copy of it (if it grew an
additional argument).

f1e94c6f29 Replace the if_name and if_unit members of struct ifnet with new members
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.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

o track bpf changes (use BPF_TAP and BPF_MTAP)
o track vlan changes (ifnet capabilities, revised processing scheme, etc.)

This driver was written by Myson and is made available
by their courtesy.
The 5.x version is not fully tested (I will be testing) but
the 4.x version has been tested by many.
I will commit it soon.
Myson have their own chip design based on the DEC 214xx family but
with several differences. Myson sells this chip to several
EOMs in teh Chinese area so there may be many noname brand cards
that respond to this driver. Myson will be supplying a list
of some of these.
