[dpdk-dev] vmxnet3 RX VLAN Strip offload incorrect behaviour

2018-04-06 Thread Padam Jeet Singh
Hi, When configuring the vmxnet3 based ethernet device, the RX VLAN Strip offload does not work as it usually does with other real NICs which support this function. When configuring with rxmode.hw_vlan_strip = 1, the ipackets statistic does not increase when a VLAN ether type frame is received

Padam, As far as I know, this feature works. What DPDK version did you use? Is there any port reconfiguration (stop/start/mtu change, etc) that could lose your vlan offload settings (a dump of the port config at runtime will be able to confirm this)? Can you also post a snippet of packet cap

When using 4095, I assume you enabled trunk mode on ESX vswitch. What ESX version did you use? Is the vswitch standard switch or DVS? We have tested over ESX6.0 and onwards plus DPDK 17.05 and it should work. On 4/8/18, 11:22 PM, "Padam Jeet Singh" wrote: > On 06-Apr-2018, at 11:12

Hi, Does anyone have a work-around for this? Should we debug the vmxnet3 driver since for sure this issue is even coming in standard l2fwd example. Thanks, Padam > On 12-Apr-2018, at 11:52 AM, Padam Jeet Singh > wrote: > > > >> On 10-Apr-2018, at 11:43 AM, Yong Wang wrote: >> >> When usi
