This function is not really necessary given what it does. If you prefer
to keep it, please rename it to vmxnet3_dev_update_vlan_filters to be more
precise.

Rather than clearing all vlan filters, we should restore the saved filters
in shadow_vfta before promiscuous mode is enabled. This is also needed
when the device is stopped/restarted.

Since you already defined rxConf, vf_table can be defined as:
uint32_t *vf_table = rxConf->vfTable;

Remove on tab here for better indention.

devRead can be defined before vf_table and vf_table as
devRead->rxFilterConf.vfTable.

There is a missing REG write after making changes to uptFeatures from
the .vlan_offload_set callback path (i.e, when ?clear" is 0).
VMXNET3_WRITE_BAR1_REG(sc, VMXNET3_REG_CMD, VMXNET3_CMD_UPDATE_FEATURE);

Remove one tab here for better indention.
Instead of uint32_t, change it to sizeof(*hw->shadow_vfta) to be
consistent with the memset of vf_table.

Same here.
