FIFO or the in-RAM descriptors it will switch to RX_IDLE from where it
is not restarted.
We used to deal with RX_IDLE by doing a total reinit but this lost
our link and caused a potential 30sec autonegotiation against
switches. This was changed to a less heavyhanded approach, but this
failed to restart the receiver it it were in the RX_IDLE state.
This change adds the RX_IDLE and the RX_FIFO_OFLOW conditions as
triggers for interrupts and receive side processing, and restarts
the receiver when it is RX_IDLE.
Remove the #ifdef notyet'ed nge_rxeoc() function.

This solution is far from perfect, as after umass_attach has returned

event that is sent to userland. It just makes the chances of collisions
less likely.

This hack turns out to be a bad idea. Many auto configuration scripts
will #include a bunch of system headers, run it through cpp and then
grep/sed to see if there was really a prototype. The regular
expressions that are used to test this didn't accept all possible
legal ANSI-C prototypes. In particular, they didn't accept the ()
around ioctl. Several different programs do this, so eliminating the
parans will keep FreeBSD maximally compatible with other systems.
Appologies to: obrien (he was right in the end)
This potentally breaks some ports (and fixes vim and others that
haven't been fixed to deal with the parens).

like the isa, eisa, and pci devices are now in the MD NOTES section even
though they have some MI code. This will ensure that only the proper bits
of device drivers will be included due to the optional bits dependent on
the busses in sys/conf/files. This commit also takes the stance that since
hints are ignored in NOTES anyways, it is ok to include hints for a bus
that may not be present.
