[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.

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?

I think this is a fix, since vlan filter is already be promised by ice_dev_info_get.

So add below fix line.
Fixes: 690175ee51bf ("net/ice: support getting device information")

Some typo, reword to

  VLAN filter is required to be configured during dev_start according to dev_conf.rxmod.offloads
setting, so ice_vlan_offload_set is called to handle this.

Applied to dpdk-next-net-intel with above changes.

Thanks
