From: Keegan Freyhof <[email protected]> Remove support for the VMDq feature from the driver: the multi-pool Rx-queue configuration path in bnxt_mq_rx_configure(), the VMDQ VLAN pool wiring in the L2 filter alloc path, and the max_vmdq_pools/ vmdq_queue_num reporting in dev_info (now always reported as 0).
Preserved two pieces of logic that live in the same function/switch statement but are not VMDq-pool-specific: the RTE_ETH_MQ_RX_RSS pools=rx_cosq_cnt case and the per-non-default-VNIC skip_filter_allocation guard in bnxt_mq_rx_configure(), both used by the plain multi-COS RSS path. Also kept the RTE_ETH_VMDQ_ACCEPT_HASH_UC/BROADCAST/MULTICAST -> l2_rx_mask flag mapping in rte_pmd_bnxt_set_vf_rxmode(): despite the name, those bits are the standard DPDK VF-rxmode API used regardless of hardware VMDq pool support, not a VMDq-pool-specific control.
