[dpdk-dev] [PATCH v2] net/ice: enable VLAN filter offloads support

[Stillwell Jr, Paul M]

Your patch description says we should be checking dev_conf.rxmode.offloads should be checked to enable VLAN, but I don't see the patch checking for that. What am I missing?

Subject: [dpdk-dev] [PATCH v2] net/ice: enable VLAN filter offloads support

There is need to check whether dev_conf.rxmode.offloads is set when start ice device, if one of the vlan related bits is set, for example DEV_RX_OFFLOAD_VLAN_FILTER and so on, sevice start process to enable this offloads request.
