40 * Fake length for RXQ descriptors in equal stride super-buffer mode
41 * to make hardware happy.
43 #define SFC_EF10_ESSB_RX_FAKE_BUF_SIZE 32
46 * Minimum number of Rx buffers the datapath allows to use.
48 * Each HW Rx descriptor has many Rx buffers. The number of buffers
49 * in one HW Rx descriptor is equal to size of contiguous block
50 * provided by Rx buffers memory pool. The contiguous block size
51 * depends on CONFIG_RTE_DRIVER_MEMPOOL_BUCKET_SIZE_KB and rte_mbuf
52 * data size specified on the memory pool creation. Typical rte_mbuf
53 * data size is about 2k which makes a bit less than 32 buffers in
54 * contiguous block with default bucket size equal to 64k.
55 * Since HW Rx descriptors are pushed by 8 (see SFC_EF10_RX_WPTR_ALIGN),
56 * it makes about 256 as required minimum. Double it in advertised
57 * minimum to allow for at least 2 refill blocks.
59 #define SFC_EF10_ESSB_RX_DESCS_MIN 512
62 * Number of Rx buffers should be aligned to.
64 * There are no extra requirements on alignment since actual number of
65 * pushed Rx buffers will be multiple by contiguous block size which
66 * is unknown beforehand.
68 #define SFC_EF10_ESSB_RX_DESCS_ALIGN 1
71 * Maximum number of descriptors/buffers in the Rx ring.
72 * It should guarantee that corresponding event queue never overfill.
