1. Feature Overview: a) Name of feature: Vlan tag strip in ixgbe PF function b) Feature Description: Currently, vlan tag strip at ixgbe_vf function, but at some NFV environment, customer hope we could achive this function at PF site. 2. Feature Details: a) Architectures: x86_64 b) Bugzilla Dependencies: None c) Drivers or hardware dependencies: ixgbe, intel 82599 d) Upstream acceptance information: e) External links: f) Severity (H,M,L): M g) Feature Needed by: ZTE, one NEP partner of redhat 3. Business Justification: a) Why is this feature needed We are doing a NFV project with ZTE. In the project, this feature is important for customer, in their environment, they don't handle vlan tag strip by dpdk. b) What hardware does this enable? c) Is this hardware on-board in a system (eg, LOM) or an add-on card? add-on card, intel 10GB netcard d) Business impact? At NFV area, any performance improve about virtulization could be appreciate. e) Other business drivers: 4. Primary contact at Red Hat, email, phone (chat) Hua Huang huhuang Jun Hu juhu 5.

Linville from comment #3) > *** This bug has been marked as a duplicate of bug 1270849 *** Here is about to strip at PF, not at VF. The other bug seems to about a malfunction in VF vlan stripping, so another issue. Wanglujing, could you review and confirm? Also, when you say "hope we could achive this function at PF site" does that mean you want to control each VF independently from PF or enable/disable vlan stripping for ALL VFs in PF? Another question is if you need per queue or not, do you? One last question, is it only about single tagging or double tagging too? The HW seems to support stripping only for one level. fbl yes, we want to set enable/disable vlan stripping for all VFs in PF driver. need per queue. single tagging. thanks. any progress? we can refer the implementation like rte_eth_dev_set_vlan_strip_on_queue function in DPDK. another question: can "ethtool -K $VF rxvlan on" enable vlan stripping in vm ? |
