what is the limit on the arp cache entires ?! Does someone have very big LANs with linux-routers ? How big ? (i mean flat L2 network, not segmented) I want to know how much can my net can scale ? thanx _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Changes since v9: * series re-ordering so make functionality more distinct. Basic vlan filtering is patches 1-4. Support for PVID/untagged vlans is patches 5 and 6. VLAN support for FDB/MDB is patches 7-11. Patch 12 is still additional egress policy. * Slight simplification to code that extracts the VID from skb. Since we now depend on the vlan module, at the time of input skb_tci is

Based on net-next. This patch exports port->port_no port->port_id in the end of IFA_INFO_DATA.

This series of patches provides an ability to add VLANs to the bridge ports. This is similar to what can be found in most switches. The bridge port may have any number of VLANs added to it including vlan 0 priority tagged traffic. When vlans are added to the port, only traffic tagged with particular vlan will forwarded over this port. Additionally, vlan ids are added to FDB entries and become

All except ''mark'' is parsed like parse_xxxx(&argc, &argv, sel, ..) and mark is parsed parse_mark(&argc, &argv, n,..) where sel is a struct tc_u32_sel and n is a struct nlmsghdr.
