2008-11-08Take into account that our ether_input() already strips theMarco Pfatschbacher
ethernet header. This lets us actually process the incoming LACP-Packets. It should now work with a lot more switches. At least a Catalyst 3500 seems happy. OK brad@
2008-11-04Move the trunk port count check from trunk_lb_start() to trunk_start()Brad Smith
before the protocol start routine is called so as to cover all protocols with the same check. ok mpf@

2008-10-28Show the ACTIVE flag in ifconfig for the single interface that isBrad Smith
actually active in failover mode rather than all interfaces with a link. This makes it clear if the master interface is in use or one of the backup links. From FreeBSD Tested by jmc@ Ok mpf@
2008-10-02First step towards cleaning up the Ethernet driver ioctl handling.Brad Smith
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. Shrinks the i386 kernels by.. RAMDISK - 1024 bytes RAMDISKB - 1120 bytes RAMDISKC - 832 bytes Tested by martin@/jsing@/todd@/brad@ Build tested on almost all archs by todd@/brad@ ok jsing@

2008-08-06fix trunk breakage that sneaked in with the lacp diff:Reyk Floeter
- don't use in-kernel IFMEDIA ioctls in lacp and remove two KASSERTs that caused reliable panics - the lacp key can be locally assigned and we don't need to query the media subtype here. - unbreak failover/loadbalance/broadcast status handling. Reported by brad@ ok deraadt@

used w/out any trunkports. Patch from Dmitri Alenitchev. OK reyk@
2008-06-15Add 802.3ad LACP support for trunk(4).Marco Pfatschbacher
Implementation from NetBSD. Ported via FreeBSD's version in trunk^Wlagg(4). This is still work in progress. Tested with a HP ProCurve 3500. OK reyk@
2008-06-14Move bpf_mtap_hdr() above the trunk_*_input() routines.Marco Pfatschbacher
This makes it easier to add trunk protocols that consume some packets. Add a special case for the failover protocol, to prevent shoving duplicates to bpf. (Not beautiful, but it has to do for the moment). OK reyk@, claudio@
2008-06-13Move the responsibility to free received packets on trunked interfacesMarco Pfatschbacher
from ether_input() into trunk_input() where it can be handled in a smarter way. OK claudio@ and reyk@ on an earlier version.
2008-06-08Use m_freem() instead of m_free() in trunk_start() to ensure that theBrad Smith
full mbuf chain is being free'd. ok reyk@
2008-05-07enable tx mitigation when putting packets on the wire by switching fromDavid Gwynne
calls to ifp->if_start to if_start(). these are the obviously right cases where we can do that, the less obvious ones may follow as theyre figured out. deraadt@ said to go for it

2007-09-06With a trunk(4) interface in fail over mode the trunk(4) interfaceReyk Floeter
will show input errors for packets received from any of the ports that are part of a fail over interface but are not the "master" port at the time. This fixes the problem by checking the error condition correctly. From brad at comstyle dot com

2007-04-26extend the trunk protocol API with some additional callbacks requiredReyk Floeter
for future work. also move the repeated tx start code into a common function. parts of it are merged from FreeBSD's trunk(4) port. oh, wait... they renamed it to 'lagg(4)' because a little green guy from Cizzco-Eeeh told them "trunk is for VLANs, trunk is for VLANs". Bad FreeBSD, don't listen to the little green guy from Cizzco-Eeeh! ok claudio@
2007-01-31handle the full duplex link state in trunk(4). load sharing trunksReyk Floeter
with at least two ports are always handled as full fuplex links. this change will allow trunks as edge ports in a rstp bridge(4). ok brad@ pyr@

drivers report an active link state even if the interface is DOWN. this should fix trunk with various ethernet devices. ok brad@

error counter. just silently drop them... figured out by todd@, ok brad@
2006-05-16the ifp->if_linkstatehooks may be NULL, add an extra check to avoidReyk Floeter
possible kernel panic. this happened to me by using tun(4) in layer 2 mode (link0 flag) as a trunk port for testing.
