The only reason why bulk alloc disabled for the rings with more than (I40E_MAX_RING_DESC - RTE_PMD_I40E_RX_MAX_BURST) descriptors is the possible out-of-bound access to the dma memory. But it's the artificial limit and can be easily avoided by allocating of RTE_PMD_I40E_RX_MAX_BURST more descriptors in memory. This will not interfere the HW and, as soon as all rings' memory zeroized, Rx functions will work correctly. This change allows to use vectorized Rx functions with 4096 descriptors in Rx ring which is important to achieve zero packet drop rate in high-load installations.
