I am working with Arkady on VLAN steering. I have few questions regarding it on
top of what was asked before.
22.214.171.124 "VEB/VEPA Switching Algorithm" states that filtering happens by
MAC+VLAN. It is impossible to perform filtering by VLAN only, as I understand
it is HW limitation.
XL710 has something called "126.96.36.199 S-comp Forwarding Algorithm" which looks
like exactly what we want. It does forwarding of packets to specific VSI based
S-tag is a part of "188.8.131.52.5.1 Add VSI (0x0210)" command. I guess we can
configure several VSIs for expected S-tags.
Do you know anything about this algorithm?
As I understood "port virtualizer" (184.108.40.206.3 "Cascaded VEB and port
virtualizers") supposed to be configured to use this switching algorithm.
In i40e driver (kernel or DPDK) I do not see anything related to configuration
of "port virtualizers", except "i40e_aq_add_pvirt" function which is not used
Is it possible to configure "port virtualizer" with existing i40e driver?
Another question is about "i40e_aq_set_vsi_uc_promisc_on_vlan" function in i40e
driver (220.127.116.11.9.5 "Set VSI Promiscuous Modes"). It enables promiscuous mode
for unicast packets with specific VLAN, so all packets with that VLAN will be
replicated to configured VSI. In XL710 datasheet I`ve found that it works only
in "Cloud VEB algorithm" (18.104.22.168). Can we somehow enable this algorithm with
existing i40e drivers?
