Re: [vpp-dev] Default setting for VLAN strip offload mode
Hi John, You are right it is VIC, I miss that is off by default for all NICs except VICs. Thanks, Matej From: John Lo (loj) Sent: 9. marca 2017 16:06 To: Matej Klotton -X (mklotton - PANTHEON TECHNOLOGIES at Cisco) <mklot...@cisco.com>; vpp-dev@lists.fd.io Subject: RE: Default setting for VLAN strip offload mode Hi Matej, Do you know which NIC/DPDK-driver it is? I do know that ENIC driver by default is initialized with VLAN tag striped, because it is more efficient with the VNIC setup on the VIC NIC. Thus it needs to be explicitly disabled in startup config. For other NIC/driver's, they are left as their default, which should mean VLAN tag is not stripped.
