[ Upstream commit ebdf7fe488c512b18add66b6c26e11e4d3830213 ]
NPAR (Network interface card partitioning)[1] 1.2 adds a transparent VLAN tag for all packets between the NIC and the switch. Because of that, RX VLAN acceleration cannot be supported for any additional host configured VLANs. The driver has to acknowledge that it can support no RX VLAN acceleration and set the NPAR 1.2 supported flag when registering with the FW. Otherwise, the FW call will fail and the driver will abort on these NPAR 1.2 NICs with this error:
bnxt_en 0000:26:00.0 (unnamed net_device) (uninitialized): hwrm req_type 0x1d seq id 0xb error 0x2
