to properly configure the right interface to use.
Also call the mediachg function when we set flags UP and are already
running. If this were a pure ifmedia driver, we'd not need to do this
since we'd be ignoring the linkX flags.
This reduces the number of ifdefs to support sub-devices a little as a
nice side effect. It also reduces the number of hpp interfaces
exposed by 33%.
man page that the ifconfig option link2 is used to disable the AUI
transceiver on the 3com boards (should also say HP PC Lan+). This
makes the connection clearer.
Add a note about why we set this flag prior to attaching the device.
We never set or clear the flag later, only test it. There can be no
races here, but this might be asthetically displeasing to some. Also
note that we may no longer need to have this knob at all as we may be
able to do it with the more sophisticated rc.d scripts we have today I
think the only reason it is there is because we didn't used to allow
its proper setting when configured to get the IP address via DHCP.
I'll note that this would be better handled by using ifmedia for all
ed cards, not just those with a miibus...
This is important with MegaLib, when issuing a GET_REBUILD_PROG since
it returns an error if the drive is not in rebuild state.

PPPoE AC, servicing a specific Service-Name, when client sends a PADI
with an empty Service-Name. Should it reply with all available service
names or should it be silent? Our implementation had chosen the latter,
while some other had chosen the former (they say Linux and Cisco). Now
some PPPoE clients appear, that rely on the assumption that AC will
send all names in a PADO reply to a PADI with wildcard Service-Name.
These clients can't connect to FreeBSD AC.
I have requested comments from authors of RFC2516 via email, but
received no reply.
This change makes FreeBSD AC compatible with D-Link DI-614+ and
D-Link DI-624+ SOHO routers, and probably others.
Big thanks to D-Link's Russian office, namely Victor Platov, for
assistance and support in investigation and testing of this change.
Details:
o Split pppoe_match_svc() into three different functions serving
different purposes:
- pppoe_match_svc() - match non-empty Service-Name tag from PADI
against all available hooks in listening state.
- pppoe_find_svc() - check that given Service-Name is not yet
registered.
- pppoe_broadcast_padi() - send a copy of PADI packet with empty
Service-Name tag to all listening hooks.
o For NGM_PPPOE_LISTEN message use pppoe_find_svc().
o In ng_pppoe_rcvdata() in a PADI case use pppoe_match_svc() for
a non-empty Service-Name tag, and pppoe_broadcast_padi() in
either case.
A side effect from the above changes is that now pppoed(8) and mpd
will reply to a empty Service-Name PADI sending a PADO with two
Service-Name tags - an empty one and correct one. This is not fatal,
and will be corrected in pppoed(8) and mpd later. No need to update
node interface version.

It should play nicely with the existing BSD ptys.

The max number of pty that can be allocated on a system can be changed with the
