Move calling ether_ioctl() from the top of the ioctl function, which
at the moment does absolutely nothing, to the default switch case.
Thus allowing drivers to define their own ioctl handlers and then
falling back on ether_ioctl(). The only functional change this results
in at the moment is having all Ethernet drivers returning the proper
errno of ENOTTY instead of EINVAL/ENXIO when encountering unknown
ioctl's.

stripping: Add a field to the mbuf pkthdr to hold the tag and an
mbuf flag that tells if the tag is valid. Inspired by FreeBSD.
Struct packing suggested by kettenis@. csum_flags is now 16 bits.
Adapt to this in the drivers.

In some situations we were not clearing pending link state attentions.
Because of this we were not getting further interrupts for link state
changes, thus never went into iface UP state.
Force an interrupt at the end of bge_ifmedia_upd so we will call
bge_link_upd, clear the link state attention and get further
interrupts.

some cards if asf/ipmi support is added.

- Add discarded RX packets to input errors for the BCM5705 or newer
chipsets. Unfortunately output errors cannot be added because the
equivalent to the ifOutDiscards register does not exist.

BGE_MAC_STATS. They were reversed but just happened to work.

the multicast filter is programmed.
IFF_ALLMULTI is for use by the driver and only the driver, meaning that we
have to clear it when its not needed anymore.
now that the ethernet layer counts the number of multicast address ranges
we can check that early to determine if ALLMULTI is needed, rather than
doing the stupid goto allmulti dance as we iterate over the multicast
address list.
the imperfect multicast filter is a 16 byte wide bitfield, so we can use
the "setbit" macro to build it in memory, and then write it to the hardware
as a bus_space region. this simplifies the code a lot and avoids confusing
bitshifts on u_int32_ts to get the bits in the right place.
tested by krw on amd64, naddy on alpha, deraadt on sparc64, and beck on
various bits.
