| /* Capability TLV types |
| * |
| * %NFP_NET_CFG_TLV_TYPE_UNKNOWN: |
| * Special TLV type to catch bugs, should never be encountered. Drivers should |
| * treat encountering this type as error and refuse to probe. |
| * |
| * %NFP_NET_CFG_TLV_TYPE_RESERVED: |
| * Reserved space, may contain legacy fixed-offset fields, or be used for |
| * padding. The use of this type should be otherwise avoided. |
| * |
| * %NFP_NET_CFG_TLV_TYPE_END: |
| * Empty, end of TLV list. Must be the last TLV. Drivers will stop processing |
| * further TLVs when encountered. |
| * |
| * %NFP_NET_CFG_TLV_TYPE_ME_FREQ: |
| * Single word, ME frequency in MHz as used in calculation for |
| * %NFP_NET_CFG_RXR_IRQ_MOD and %NFP_NET_CFG_TXR_IRQ_MOD. |
| * |
| * %NFP_NET_CFG_TLV_TYPE_MBOX: |
| * Variable, mailbox area. Overwrites the default location which is |
| * %NFP_NET_CFG_MBOX_BASE and length %NFP_NET_CFG_MBOX_VAL_MAX_SZ. |
| * |
| * %NFP_NET_CFG_TLV_TYPE_EXPERIMENTAL0: |
| * %NFP_NET_CFG_TLV_TYPE_EXPERIMENTAL1: |
| * Variable, experimental IDs. IDs designated for internal development and |
| * experiments before a stable TLV ID has been allocated to a feature. Should |
| * never be present in production firmware. |
| * |
| * %NFP_NET_CFG_TLV_TYPE_REPR_CAP: |
| * Single word, equivalent of %NFP_NET_CFG_CAP for representors, features which |
| * can be used on representors. |
| * |
| * %NFP_NET_CFG_TLV_TYPE_MBOX_CMSG_TYPES: |
| * Variable, bitmap of control message types supported by the mailbox handler. |
| * Bit 0 corresponds to message type 0, bit 1 to 1, etc. Control messages are |
| * encapsulated into simple TLVs, with an end TLV and written to the Mailbox. |
| * |
| * %NFP_NET_CFG_TLV_TYPE_CRYPTO_OPS: |
| * 8 words, bitmaps of supported and enabled crypto operations. |
| * First 16B (4 words) contains a bitmap of supported crypto operations, |
| * and next 16B contain the enabled operations. |
| * This capability is made obsolete by ones with better sync methods. |
| * |
| * %NFP_NET_CFG_TLV_TYPE_VNIC_STATS: |
| * Variable, per-vNIC statistics, data should be 8B aligned (FW should insert |
| * zero-length RESERVED TLV to pad). |
| * TLV data has two sections. First is an array of statistics' IDs (2B each). |
| * Second 8B statistics themselves. Statistics are 8B aligned, meaning there |
| * may be a padding between sections. |
| * Number of statistics can be determined as floor(tlv.length / (2 + 8)). |
| * This TLV overwrites %NFP_NET_CFG_STATS_* values (statistics in this TLV |
| * duplicate the old ones, so driver should be careful not to unnecessarily |
| * render both). |
| * |
| * %NFP_NET_CFG_TLV_TYPE_CRYPTO_OPS_RX_SCAN: |
| * Same as %NFP_NET_CFG_TLV_TYPE_CRYPTO_OPS, but crypto TLS does stream scan |
| * RX sync, rather than kernel-assisted sync. |
