Oh, I forgot to mention: this driver also works on FreeBSD/alpha (big
thanks to Andrew Gallatin). And there is a 2.2.x version available for
those who stubbornly refuse to upgrade.
Networks Tigon 1 and Tigon 2 chipsets. There are a _lot_ of OEM'ed
gigabit ethernet adapters out there which use the Alteon chipset so
this driver covers a fair amount of hardware. I know that it works with
the Alteon AceNIC, 3Com 3c985 and Netgear GA620, however it should also
work with the DEC/Compaq EtherWORKS 1000, Silicon Graphics Gigabit
ethernet board, NEC Gigabit Ethernet board and maybe even the IBM and
and Sun boards. The Netgear board is the cheapest (~$350US) but still
yields fairly good performance.
Support is provided for jumbo frames with all adapters (just set the
MTU to something larger than 1500 bytes), as well as hardware multicast
filtering and vlan tagging (in conjunction with the vlan support in
-current, which I should merge into -stable soon). There are some hooks
for checksum offload support, but they're turned off for now since
FreeBSD doesn't have an officially sanctioned way to support checksum
offloading (yet).
I have not added the 'device ti0' entry to GENERIC since the driver
with all the firmware compiled in is quite large, and it doesn't really
fit into the category of generic hardware.
to now detect that CD you just remembered to put in the drive or that
pccard NIC that you've inserted (anybody can put pccardd in an mfsroot image
now you know.. :)

1. Switch to pmap_TLB_invalidate from invltlb, eliminating a full TLB
flush where a single-page flush suffices. (Also, this eliminates some
unnecessary IPIs.)
2. Use "loadandclear" to update the pte, eliminating a race condition
on SMPs.
Change #2 should be committed to -STABLE.
which init thoughtfully revoke()'s when starting a getty on ttyv0. This
Cron's popen() was passing these fd's through to cron children (ie:
sendmail, *not* normal cron jobs). The side effects were usually
not noticed, but it tripped up postfix which did a sanity check to see
that stdin/out/err were open, and got EBADF even thought the fd's were
in use. I seem to recall sendmail itself has hacks to work around
this problem, it had a checkfd012() function, possibly for this same
problem. (Postfix has a workaround too now though..)
This is a hack, not a fix. It's probably best to check and perhaps
close/reopen() /dev/console if needed each time around the event loop.
It would probably be useful to actually see any error messages from cron.
lookup on the incoming IP, do a forward lookup on
the result and make sure that the IP is in the
resulting list. If it's not, put the IP number
in utmp/wtmp instead of the rogue name.
