Introduce the foundational building blocks for SR-IOV Virtual Function support on Broadcom NetXtreme-C/E adapters. * Add bnxt_sriov.h: defines the extended bnxt_vf_info structure (per-VF firmware FID, MAC addresses, VLAN, flags, DMA command buffers, resource counts), the bnxt_resc_map helper, flag macros (BNXT_VF_TRUST, BNXT_VF_SPOOFCHK, etc.), and prototypes for all SR-IOV functions. * Add bnxt_sriov.c: implements the SR-IOV attachment sequence (bnxt_sriov_attach), the iflib IOV callbacks (bnxt_iov_init, bnxt_iov_uninit, bnxt_iov_vf_add), VF resource allocation and firmware configuration helpers (bnxt_alloc_vf_resources, bnxt_cfg_hw_sriov, bnxt_hwrm_func_vf_resc_cfg, bnxt_hwrm_func_buf_rgtr, bnxt_hwrm_func_vf_resource_free), and the per-VF parameter helper. * Extend bnxt.h: include bnxt_sriov.h; extend bnxt_pf_info with VF- tracking fields (vf array, firmware FID/MAC, resource-reservation strategy, DMA page management, sysctl context); replace the upstream bnxt_vf_info stub with the full definition from bnxt_sriov.h; extend bnxt_func_qcfg with allocation counters required by the VF resource configuration path; add vf_resc_cfg_input and sriov_lock to bnxt_softc. * Update Makefile to build bnxt_sriov.c and include bnxt_sriov.h. * Wire up PCI-IOV device methods (pci_iov_init / pci_iov_uninit / pci_iov_add_vf) and iflib IOV callbacks (ifdi_iov_init / ifdi_iov_uninit / ifdi_iov_vf_add) in if_bnxt.c; call bnxt_sriov_attach() from bnxt_attach_post() on P5+ Physical Functions.
