How can I get Intel X710 SR-IOV netmap driver #822

Open missyoyo opened 2 years ago

missyoyo commented 2 years ago

Hello: I have check netmap/LINUX/final-patches/ I can netmap git provide intel 82599 and 82599 SR-IOV(ixgbevf) driver. ixgbe/ixgbevf: call a driver-specific netmap detach function I also find intel X710 netmap driver(intel--i40e),But I can not find X710 SR-IOV(VF) driver. May I know some different between 82599 and X710 VF? Does X710 VF do not need special netmap driver OR X710 VF can not apply netmap driver? I have do some test witch tcpdump. with X710 PF I can tcpdump 0.8Mpps with zore packet loss. But when use X710 VF I get some some "poll error on queue 0: timeout" Message at pkg-gen send side,And tcpdump receive side get 2% packet loss(8823492/9000000=98%)

the iavf driver (X710 and E810 VF driver) could be modified / patched just like i40e was with the netmap native enabling. There is nothing that should prevent a user from running netmap in native mode inside a VM on top of a VF.

@jbrandeb or anyone else could help me to add iavf patch for netmap?
