* [legal] Relicense files under GPL2_OR_LATER_OR_UBDLMichael Brown2015-03-021-1/+5
| | | | | | | | | | These files cannot be automatically relicensed by util/relicense.pl since they either contain unusual but trivial contributions (such as the addition of __nonnull function attributes), or contain lines dating back to the initial git revision (and so require manual knowledge of the code's origin).

* [lacp] Set "aggregatable" flag in response LACPDUSven Ulland2014-07-231-1/+2
| | | | | | | | | | | | | Some switches do not allow an individual link (as defined in IEEE Std 802.3ad-2000 section 43.3.5) to work alone in a link aggregation group as described in section 43.3.6. This is verified on Dell's PowerConnect M6220, based on the Broadcom Strata XGS-IV chipset. Set the LACP_STATE_AGGREGATABLE flag in the actor.state field to announce link aggregation in the response LACPDU, which will have the switch enable the link aggregation group and allow frames to pass.

* [netdevice] Allow link layer to report broadcast/multicast packets via pull()Michael Brown2011-07-151-1/+3
| | | | | | | | Allow the link layer to directly report whether or not a packet is multicast or broadcast at the time of calling pull(), rather than relying on heuristics to determine this at a later stage. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [netdevice] Pass both link-layer addresses in net_tx() and net_rx()Michael Brown2010-10-071-2/+5
| | | | | | | | | FCoE requires the use of fabric-provided MAC addresses, which breaks the assumption that the net device's MAC address is implicitly the source address for net_tx() and the (unicast) destination address for net_rx(). Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [build] Fix misaligned table entries when using gcc 4.5Piotr Jaroszyński2010-08-201-1/+1
| | | | | | | | | | Declarations without the accompanying __table_entry cause misalignment of the table entries when using gcc 4.5. Fix by adding the appropriate __table_entry macro or (where possible) by removing unnecessary forward declarations.

* [lacp] Add simple LACP implementationMichael Brown2010-05-101-0/+267
Some switch configurations will refuse to enable our port unless we can speak LACP to inform the switch that we are alive. Add a very simple passive LACP implementation that is sufficient to convince at least Linux's bonding driver (when tested using qemu attached to a tap device enslaved to a bond device configured as "mode=802.3ad").
