Hi All, I'm working on an Ethernet driver for FreeBSD, currently implementing VLAN offloads. I have two problems, one is enabling TSO over the VLAN interface and the second is enabling the VLAN filtering offload.
About the TSO problem, I'm currently suffering a hugh performance penalty since I have no TSO enabled over my vlan interfaces. When I create a VLAN interface it does not inherit the features of it's mother-interface, e.g. IFCAP_TSO. Can it be done on FreeBSD 6.3 / 7.0 ? Second, my NIC is capable of holding a vlan table on HW, filtering vlans on it's own, now I need to find a way to update that HW table with added/deleted VLANs in order to use that VLAN filtering offload. One way is to recieve a ioctl from the OS of it's vlan table events (add, remove). I can't find such ioctl. Second way is to have direct access from the driver to the OS vlan table. I'm not familiar with the interface though (something parallel to vlan_group_get_device on linux) or if it's possible at all, can anyone help on this one?
