Chelsio T4/T5 VF driver. The cxgbev/cxlv driver supports Virtual Function devices for Chelsio T4 and T4 adapters. The VF devices share most of their code with the existing PF4 driver (cxgbe/cxl) and as such the VF device driver currently depends on the PF4 driver. Similar to the cxgbe/cxl drivers, the VF driver includes a t4vf/t5vf PCI device driver that attaches to the VF device. It then creates child cxgbev/cxlv devices representing ports assigned to the VF. By default, the PF driver assigns a single port to each VF. t4vf_hw.c contains VF-specific routines from the shared code used to fetch VF-specific parameters from the firmware. t4_vf.c contains the VF-specific PCI device driver and includes its own attach routine. VF devices are required to use a different firmware request when transmitting packets (which in turn requires a different CPL message to encapsulate messages). This alternate firmware request does not permit chaining multiple packets in a single message, so each packet results in a firmware request. In addition, the different CPL message requires more detailed information when enabling hardware checksums, so parse_pkt() on VF devices must examine L2 and L3 headers for all packets (not just TSO packets) for VF devices. Finally, L2 checksums on non-UDP/non-TCP packets do not work reliably (the firmware trashes the IPv4 fragment field), so IPv4 checksums for such packets are calculated in software. Most of the other changes in the non-VF-specific code are to expose various variables and functions private to the PF driver so that they can be used by the VF driver. Note that a limited subset of cxgbetool functions are supported on VF devices including register dumps, scheduler classes, and clearing of statistics. In addition, TOE is not supported on VF devices, only for the PF interfaces.
